SCIENCE GAMES...

FIND THE EYEBALLS
1.
  Fill a large pot with cooked spaghetti noodles, and then bury ping pong balls in the noodles.
2.  See who can find the most balls in a set amount of time.
3.  For an added twist you can color code the balls and have each color worth a different amount of points.
4.  After the set amount of times, count up the points earned by each player.

____________________
MAD SCIENTIST SOUP
Need: Bowl full of oatmeal, Halloween type toys (or of your choice) 
1.  Find a big bowl and fill with cooked oatmeal.
2.  Put in the fridge to make it nice and cold.
3.  Mix in small plastic toys like eyeballs, bats, spiders etc.
4.  Have player close their eyes and reach in the bowl.
5.  Each player has to put their hand in and find one prize and then the next person has a go.

(I've also done this using lots and lots of Jell-O! Barb)

_____________ 

SCIENTIST ANAGRAMS -- Mix the letters up in the names of scientists and get the kids to work them out.

_____________

TREASURE HUNT

Send the kids on a treasure hunt. Make the clues slightly cryptic by using mathematical formulas and scientific words which are appropriate for their age.
1.  Example of clues: 40+5-2 is the number of steps forward before your next clue.
2.  Your next clue is where you might find H2O in the yard.
3.  What did Alexandra Graham Bell invent?

______________

WHAT AM I?
Get
participants minds spinning with this scientific version of a classic party game.
What you need:
Index cards
Pens
Tape

  • Write science words on the index cards such as: atom, constellation, electricity, magnet, microscope, or test tube.
  • Tape a different word to each guest's back without letting him or her read it.
  • Everyone then tries to discover their identities by walking around asking fellow scientists questions that can be answered with a yes or a no. Example: "Do you need a microscope to see me?" or "Do I move around?"
  • The first person who says the word on his or her back wins the game---but encourage the group to keep playing until everyone has guessed correctly.

____________________________

MAGNIFYING OBJECTS GAME

  • Before the event, take CLOSE-UP PHOTOGRAPHS of 10 to 15 everyday objects.
  • Print the pictures and put them on a colored construction paper.
  • Next draw a magnifying glass around each picture, so that these pictures look as if they are being viewed through a magnifier.
  • Instruct youth to examine the pictures and try to guess which picture represents which everyday item.
  • Since these items have been enlarged it will be a challenge to guess what the actual picture product is.
    The child who guesses the most items correctly wins the game.

_____________________ 

BURST THE ATOMS GAME: Blow up two balloons (atoms) for each guest and tie one to each of their ankles. Let the mayhem begin as the mad scientist race round the room trying to burst each others atoms but at the same time trying to preserve their own. The scientist who manages to preserve the last atom is the winner.

________________________ 

INVENTING A ROCKET BALLOON
T
his is an easy science game that will teach young scientists about Isaac Newton’s Third Law of Motion - “For every action, there is an equal and opposite reaction”.
1.  For this game you will need long, torpedo-shaped balloons, a drinking straw, string and tape.
2.  For each rocket, securely tape one end of a long string to the ceiling. Thread a drinking straw onto the string, then stretch the string taut and tape the other end to the floor.
3.  Have each child inflate a long, torpedo-shaped balloon and keep the neck pinched shut while you tape it to the straw. 
4.  While everyone holds their balloons near the floor, count down to takeoff and see whose balloon goes fastest and highest.

_______________

MAGICAL MAGNETIC TOUCH
A fun game to show the children the effect of a magnet on other objects. You need a variety of magnets several metal and non-metal products. The trick of the game is to have children guess which product will stick to the magnet once brought close to it and which will not. The participant with the most correct guesses is the winner.

MAKE A LIGHT BULB PIÑATA

 Materials:

  • Water
  • Bowl
  • All-purpose flour
  • Sugar
  • Large, round balloon
  • Newspaper strips
  • Long string Craft knife
  • Glue stick
  • Yellow paper
  • Wrapped candy
  • Aluminum foil
  • Black electrical tape
  • Black marker

 1. In a saucepan, bring 2 cups of water to a boil. In a bowl, whisk together 1/2 cup of all-purpose flour and 2 cups of cold water, then add the mixture to the boiling water. Once the solution comes back to a boil, remove the pan from the heat and stir in 3 tablespoons of sugar. When the paste cools, it will thicken and be ready to use (cover and refrigerate the paste between applications). Or...use one of the paste suggestions in the Goop Category...or Pinatas and Paper Mache. (I prefer to use liquid startch. Barb)

2. Shape the piñata by inflating a large, round balloon (about 14 inches in diameter). Tear 3 or 4 double newspaper sheets into 2-inch-wide strips. Apply the first layer of papier-mâché by individually dragging newspaper strips through the paste, wiping off the excess with your fingers, and pressing them onto the balloon so that they overlap slightly. Cover the whole balloon except for a 2-inch square opening at the knotted end. Let it dry for 24 hours. Pop the balloon.

3. Tape the midpoint of a long string to the top of the bulb, then wrap the string ends around the bulb sides, taping them in place. Let the trailing ends dangle. With a craft knife (adults only), cut an asterisk-shaped opening in the bottom of a 32-ounce plastic deli container. Fit the top of the container snugly against the bulb bottom and tape it in place. The string ends should remain outside the container...

4. Add a second and a third layer of paper-mache allowing the paper to dry in between. Cover the sides of the plastic container too, but not the container bottom nor the dangling string ends. Finally, use a glue stick to attach a layer of 5-inch yellow-paper squares to the bulb but not the container.

5. Fill the pinata (through the container bottom) with 4 pounds of wrapped candy. Glue aluminum foil to the container to simulate the neck of a lightbulb. Secure the foil with 3 strips of black electrical tape. Hang the piñata upside down.

MISCELLANEOUS SCIENCE FUN...

TOOTH PICK TOWERS

1.  Prepare large Ziploc bags with kid's names written on them...
2.  Put small Ziploc bags inside the large ones.
3.  Fill one small bag with about 100 toothpicks, another one with Tootsie Rolls, another one with Cheese Puffs, and the last one with Gummy Bears. (My grandchildren-who made this tower-decided to add a few mini-marshmallows. The tower measured 19.5 inches and then started to wobble. Barb) 
4.  The kids' task is to BUILD THE TALLEST, MOST STABLE STRUCTURE, using the materials provided.

EXTENSION IDEA: Make a Molecule Center...
You can have the kids make structures that resemble molecule shapes using the above same materials. For a more simple version, y
ou can also 'make molecules' using toothpicks or spaghetti and mini-marshmallows or gumdrops.

_____________

*Remember...COOKING AND CONCOCTIONS are all science too! Anything that starts out liquid and turns to a solid is science!!!

 ______________

 

STATIC ELECTRICITY: Give each mad scientist a balloon and an empty soda can. Have them blow up their balloons and rub them on their heads. Put soda can on flat surface, and applying the balloon, see if the can moves. Next, get the kids to stick their balloons to the wall. (Of ourse-you''ll have a 'hair-raising' good time!)

FOUR VERSIONS OF AN ERUPTING VOLCANO... 

 

Note: K-A made version #1 with grandsons 'N' and 'B'. Although the boys thought the experiement very cool, we would make the 'mountain' itself differently next time. The 'dough' material didn't want to easily stay on the bottle. After adding more salt, water and oil--we were able to make a mountain of sorts. Repeating this activity, we would use a different play dough or  modeling clay.

To the delight of the boys (ages 8 and 12), the volcano erupted for quite awhile. K-A has also successfully made volcanoes with the other methods.

Additional Note: 'N' thought it would also be cool to add 'adventure seeking climbers' to the mountain. Hence, the 'dark blobs'--aka  gummy bears-- on the face and bottom of the hill! Barb

#1 VINAGER VOLCANO

This is a classic science experiment, and an easy one. To make the volcano, mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil,and 2 cups of water. The mixture should be smooth and firm.

Stand a large soda bottle in a baking pan or shallow dish, and begin
to shape the dough around it. Don't cover the hole and don't drop any of the
dough into it.

Fill the bottle about three-quarters full with warm water and a few drops of
red food coloring. Add 6 drops of liquid detergent to the bottle, and 2
tablespoons of baking soda.

Slowly pour vinegar into the bottle and step back!

____________

VOLCANO #2

  • Fill a child’s swim pool or sandpit with lots of slightly moist sand.
  • Get the kids to each make a volcano sand mound with a hole in the center
  • Place a small disposable cup in the hole; put in 1 tablespoon of baking soda plus 2 tablespoons of water in order to make it dissolve.
  • Add 2 tablespoons of vinegar to which you have added a few drops of red food coloring, then watch it erupt!
    You can repeat the activity over and over again.

____________

VOLCANO #3
Materials you will need:
    •  1/4 Cup of Vinegar
    •  Red Food Coloring
    •  Liquid Dishwashing Soap
    •  1 Tablespoon Baking Soda
    •  Modeling Clay (Plasticine)
    •  Newspaper or Vinyl Table Cover
Steps:
1. Clear a work surface and cover it with newspaper or a vinyl table cover.
2. Model a volcano out of modeling clay. You could use red clay around the top of the volcano to make it look like red-hot lava.
3. Make a hole at the top of the volcano.
4. Stir in 1 tablespoon of baking soda
5. Add a few drops of red food coloring
6. Add a few drops of liquid dishwashing detergent.
7. Get ready! Pour in ¼ cup of vinegar and stand back!!!
The eruption is acid meeting another substance called an alkali.

____________

VOLCANO #4
1.  Before the eruption event, form a piece of modeling clay about the size of a baseball into a mountain shape.
2.  Put the shape on waxed paper.
3.  Using your fingers, pinch the sides of the clay to form lumps that look like lava coming down the sides of the volcano.
4.  Poke a hole in the middle of the volcano. Let the clay dry overnight.
5.  Paint the volcano with brown paint. Let the paint dry thoroughly.
....To make your volcano active: Put 1 tsp of baking soda in the center of the volcano. Then add 1 tbsp of vinegar to make it erupt. Watch out!

ROCKET LAUNCH (See a more detailed Rocket design in 'Popular Activities in Science Category')  

Fill a small plastic film canister (Fuji works well) with one teaspoon of water. Quickly add one Alka-Seltzer tablet, put the lid on and place the canister on the floor with the lid side down. Wait about 10 seconds and whoosh! Your rocket should fly into the air.

 _______________

GIANT BUBBLES:

Make mega bubbles using this fabulous bubble recipe. The secret ingredient for big, strong bubbles is glycerin.
Ingredients: Duish washing liquid - 1 part (many people recommend Joy or Dawn dish detergent)
Soft tap water/ Distilled Water - 15 parts
Glycerin - 1/4 part (available from drug stores)
1.  Mix all together and leave for a couple of hours.
2.  The longer you leave it the better the bubbles.
3.  Make bubble wands out of coat hangers or wire and you will have happy kids for hours.

DECORATING THE MAD SCIENCE LAB...most ideas are easy and inexpensive!

 Make one party room/area into the lab. It will be much easier to decorate and will contain the mess.

 • On the entrance to the room-- put up some danger tape and a notice warning that only scientists may enter the "Secret Science Lab Zone".

 • Using black construction paper cut out large question marks, magnifying glasses and mathematical formulas. Put these up around the room.

 • Put up posters of famous scientists around the room with a small caption underneath of why they are famous.You could also hang some science clip art pictures in the room.

 • Decorate the space with an array of lab items such as gummy frogs that have been pinned down so that they look as if they were being dissected. You can also keep jars of lab specimens like huge gummy snakes, lizards etc.

 • Check out Halloween stores/sites/for slimy table decorations which are perfect for scientists; also skeletons and other gory accessories. 

 • A dry ice machine would make a great table center piece.

 • Fill lots of different shaped jars with colored water and rubber body parts to put around the table. If you're going for a 'Frankenstein Lab' purchase cobwebs/spider webs and spread them about tables, etc.

 • Borrow microscopes, chemistry sets, molecule models, magnifying glasses, compasses, and so on, and place them on the table and about the room.

 • Use a colored globe light to give the room an eerie appearance or just place colored light bulbs in regular lamps. Do you have a flickering plasma lamp? Kids of all ages love them!

 • Set up a large chalk board/white board and write the recipes for the experiments that you are going to do.

 • Hang a sign from the table saying “Welcome to the Science Laboratory”.

 • Use a 'weird or scary font' to write signs such as "Electricity", "Gas", "Chemicals", and put them around the area.

 • Put a rubber band around several large test tubes. Tie a ribbon over the rubber band. Arrange tubes to stand with open ends up. Fill them with colored water and add a flower or two.

NOTE: Food itself is also part of decorating--make it creepy, slimy and gross! See some ideas towards this page bottom-- and also in the Halloween Snack Category.

_____________

 

 

DECORATE WITH DRY ICE AND A PLASMA LAMP...

For truly dramatic effects, create fog using dry ice. Add one piece of dry ice to every gallon of very hot water. Make foggy smoking cauldrons.   Note: Be careful and make sure that it is in a place where children cannot hurt themselves.

Whether you call them nebula spheres, PLASMA LAMPS, or lightening balls, these lamps put on one of the most unique displays available. Twenty years ago they cost $1500. Today you can get one for $40.00 or less...
Technically, they're a clear glass orb, filled with a mixture of various gases at low pressure, and driven by high frequency alternating current at high voltage...Great for decorating a 'Mad Science Lab'!!!

 

_____________________________________

MAKE LAB COATS 

 #1 Professor X Lab Coats: Cover the table with newspapers or freezer paper. Lay out fabric markers. Give each child a plain white shirt to decorate as a lab coat. You can use T-shirts, or look for used front-buttoning shirts at thrift shops

Idea #2
Use white kitchen sized garbage bags to make lab coats (A practical way to protect children's clothing during experiments)
Cut a half circle hole for the head, and half circles for the arms. With a black permanent marker, draw a line down the front and buttons next to it. You can also draw a pocket on the side with a pen in it; write the children’s names on them (Example: Professor Smith, Dr. Susan.

_________________

 

JUST LIKE EINSTEIN...
Purchase black party glasses with the noses and mustaches from a novelty or party store. Before kids enter the “science lab” have them don their coats and glasses. It would be great if staff could be wearing white lab coats, crazy wigs, goggles, or glasses too! BE SURE TO TAKE PHOTOGRAPHS of this! Kids may not leave these on long---but it will be great fun.

Kids' Science Experiments

July 3, 2009 02:43 by Barbara Shelby

 

DIET COKE & MENTOS ERUPTION (K- A tested)


(Do this outside)  This is also known as a Mentos Eruption, Soda Geyser or just Diet Coke and Mentos.
This is a reaction between Mentos candy and cola. The experiment involves dropping several Mentos candies (usually 5–8) into a bottle of diet cola resulting in an eruption occurring because of rapidly expanding carbon dioxide bubbles on the surface of the Mentos.

 

I recently tried this experiment with three of my grandsons (Ages 6, 8,11; See photo) They all loved it! We quickly put the mentos into the Coke. The reaction starts immediately-so be quick! 

If you want an explanation:
There are various theories being debated as to the exact scientific explanation of the phenomenon, many scientists claim that it is a physical reaction and not a chemical one. Water molecules strongly attract each other, linking together to form a tight connection around each bubble of carbon dioxide gas in the soda. To form a new bubble, water molecules must push away from one another. It takes extra energy to break this surface tension. So, in other words, water resists the expansion of bubbles in the soda.

When Mentos are dropped into soda, the gellan gum and gum arabic of the candy dissolves and breaks the surface tension. This disturbs the water connection, so that it takes less work to expand and form new bubbles. Each Mentos candy has thousands of tiny pores over its surface. These tiny pores function as nucleation sites, perfect places for carbon dioxide bubbles to form. As soon as the Mentos enter the soda, bubbles form all over their surface. They quickly sink to the bottom, causing carbon dioxide to be released by the carbonated liquid with which they come into contact along the way. The sudden increase in pressure pushes all of the liquid up and out of the bottle.
From: wikipedia.org

_______________________
ALKA-SELTZER ROCKET
....is a model rocket fashioned from a 35mm film canister and propelled by the generation of gas from an effervescent liquid. It is often used in science classes to demonstrate principles of chemistry and physics to students.

1.  In the experiment, a film canister is filled with water and an effervescent tablet (commonly Alka-Seltzer) and tightly sealed.
2.  After a short time, the evolved carbon dioxide reaches sufficient pressure to cause the body of the canister to be launched into the air with a popping sound.
3.  The canister may be elaborated with paper fins to resemble more closely af real rocket.

(K-A tested) MORE SIMPLE ROCKET LAUNCH... Fill a small plastic film canister (Fuji works well) with one teaspoon of water. Quickly add one Alka-Seltzer tablet, put the lid on and place the canister on the floor with the lid side down. Wait about 10 seconds and whoosh! Your rocket should fly into the air.

Lessons based around the Alka-Seltzer rocket can focus on a number of principles...

For example, the students are sometimes asked to experiment with the amounts of water and Alka-Seltzer to find the combination which propels the rocket the greatest distance.
Alternatively they may derive equations to calculate the speed and velocity of the rocket from the distance it travels.

BONES!

If budget can afford it...purchase a life sized, plastic replica of a human skeleton. The children will be able to investigate how the bones are shaped, how the sizes related to each other and how the joints are restricted or facilitate movement. Children will clearly see how their own bones work. The cost would be about $50 but will be used for many years!....
(I'm known for my wackiness! Play the song Dem Bones-Barb)

 An inexpensive and easily found alternative for hands-on skeleton activities can be found at the supermarket. Bones from turkeys', chickens' and pigs' feet can be cleaned and given to the children to reassemble.
Idea from: findarticles.com

____________

MACARONI SKELETON

  • Materials: Black construction paper (approximately 6" x 11.5")
  • Glue that will dry clear
  • Lima beans (head, thorax, hips)
  • Short, small macaroni in a tube (spine)
  • Thin twisted macaroni (arms, legs)
  • Elbow noodles (ribs)
  • Small shells (joints)
  • Spaghetti (fingers, toes)
  • Black permanent marker

Directions:
1. Build a sample skeleton for the children to copy from. Review the key features with them. 2. Guide children to  build their skeleton working from the head down (i.e., head, neck/trunk, ribs, etc.), gluing the macaroni and beans to the paper as they go.
3. When they glue and macaroni has set, have them draw a smile and eyes on the "head".
TIPS:
As preparation for this project, study the human skeleton. Talk about symmetry between the two sides of the body, and how many ribs, fingers and toes we have. Source: Kaboose.com

 WET DIAPER SCIENCE

 

What you Need: Diapers, resealable plastic bags, clear plastic cups, plastic teaspoons, water, blue food coloring


What to Do:

Show students a diaper. Once the giggles subside, ask them to guess how much water they think the diaper can hold, and record their responses.

  • Invite small groups to cut out the waist and leg bands of a diaper and place the remainder in a bag.
  • Separate the layers of the diaper and seal the bag.
  • Shake the bag for two minutes. Kids will see a dry powder resting at the bottom. Have them remove everything from the bag except for this powder.
  • Pour the powder (sodium polyacrylate) into a cup.
  • Ask students to pour four ounces of water into a separate cup and add four drops of blue food coloring.
  • Slowly spoon water into the cup with the powder, keeping track of the amount as you go.
    How does the powder change? (It should now be a gel.)
    Challenge students to predict how much more water this gel can hold.
  • Continue to add spoonfuls of water, keeping track of the amount of water added and recording observations along the way, until the water no longer soaks into the gel. Ask students to determine how much water the powder can hold.
    WHAT'S GOING ON: Sodium polyacrylate is a super-absorbent polymer that absorbs up to 300 times its weight in water. It is used in baby diapers to keep wetness away from a baby's skin. This polymer is also used as a soil substitute.

 'MOO GOO' (K-A tested; image by K-A)

Ingredients: 1 cup whole milk, 2 Tablespoons white vinegar, Stove top or hot plate, small pot and strainer

Warm the milk in a pan, but do not boil. Remove the pan from the heat and SLOWLY stir in the vinegar. (The first time we made this, my grandson put the vinegar in at one time (it did not work)--when repeated and drizzled in slowly--it came together quickly. Barb)

  • Continue to stir until a white rubbery substance forms in the liquid.
  • Strain the liquid from the rubbery substance. If you've done the above diaper experiment, kids may correctly guess that they have created a polymer.
  • Divide the polymer among youth and ask them to gently pat and roll it to remove any remaining liquid. (With this recipe there is only enough for one or two balls) 
    Test its physical properties. Kids will discover it stretches, bounces, and sticks to a surface.

WHAT'S GOING ON: This is a very nasty-tasting, yet edible, experiment. Cow's milk is loaded with the polymer casein, a protein. Without this polymer, cheese would come unglued. The casein is suspended in milk, but the vinegar causes cross-linking of the casein chains, resulting in visible clumping of the polymer. Casein is used in some glue. Without casein, glue would come unglued too.

 EGG DROP (K-A tested-the grade school and middle school kids loved it!)

Each student works within guidelines to fashion a container for an egg so that the egg won't break when the student drops it from an established height…

Use hard boiled eggs (you could probably do raw-but be cautious of Salmonella and spoilage!).

Have each child create their own container for the egg -- with the purpose of the egg not breaking. Some kids have used "parachutes," and cans with foam. It can be a lot of fun!

Of course, everyone's hypothesis should be that their egg won't break.
The testing is the fun part---when the kids see if their egg remains intact! For this you want to drop the egg container from the highest available point.... A second floor balcony, off the top bleacher of the football field or by a teacher on a ladder?
*Even though this is for older students, it can be adapted to the lower grades without going into weight and velocity.

MIRROW DRAWING
Materials you will need:
Pencil
Paper
Mirror
Steps:
1. Draw a simple shape like a star or heart.
2. Place the mirror upright behind your drawing so that you can see it in the mirror.
3. Try drawing over your shape while looking into the mirror (keeping your eyes on the mirror all the time and not your paper).
When looking in the mirror, the top of your picture becomes the bottom. This makes it very difficult to copy your drawing (especially when the lines change direction).

________________

INVISABLE INK
Materials:
2 tablespoons of pure lemon juice and cotton swabs

  • Pour the lemon juice into a small dish.
  • Soak the end of a cotton swab in the lemon juice and use it to write a secret message or a picture.
  • To read or see your secret message, hold the paper near a warm light bulb, burner, or toaster.
  • The heat will turn the invisible writing brown and you can see it!

WHIRLY GIG SPINNER--HOW LONG CAN YOU SPIN?
Need:
Film canister lid
Construction paper
Bamboo skewer
Tape
Scissors
1.  Cut a circle out of construction paper, about the size of a DVD or CD.
2.  Tape a film canister lid to the center of the paper circle. (You can draw a design on it-that would look interesting spinning)
3.  With an adult- poke or drill a hole through the film canister lid.
4.  Poke the skewer through the hole in the lid.
5.  Keep the paper circle near the point of the skewer. Give the skewer a twirl.

HOW DOES IT WORK?
The paper circle gives the skewer extra mass. When you twirl the skewer, you also twirl all the mass of the paper circle. A spinning mass tends to keep spinning unless something like friction slows it down.
About 72% of kids can make it spin MORE than 10 seconds...

BOTTLED AIR
You will need an empty soda bottle and deflated balloon.
1.  Show an empty soda bottle to the group & announce that although the bottle may look empty, you can prove that it's actually full.
2.  Put a deflated balloon into the bottle---stretching the open end of the balloon over the mouth of the bottle.
3.  Can your friend blow up the balloon while it's inside the bottle?? NO WAY!
4.  WHY? No matter how hard you blow, you will not be able to blow up the balloon while it is inside the bottle. This is because the bottle is already completely full--of air. Even though it's invisible, air takes up space.

DOLLAR PICK UP TRICK
Even George Washington couldn't do this dollar pick-up trick! Tell the children you'll give them each a dollar if they can pick it up from the floor. But there is a catch: They have to pick it up using your instructions. You'll have fun fooling them with this easy indoor game for kids.
You'll need a dollar bill and a wall…
Step 1: Have children stand with their feet together and heels up against a wall.
Step 2: Put dollar bills on the floor 12 inches in front of their feet.
Step 3: Tell them to pick up the dollars without bending their knees or moving their feet.
It is impossible to do! Why? When you are standing against a wall, your center of gravity is over your feet. If you bend forward, you have to move your center of gravity forward to keep your balance. Since you can't move your feet during this trick, you're flat out of luck. But that's better than being flat on your face!

RINGING EARS
Materials:
A Fork
A Spoon
3 feet of String/Thread
Steps:
1. Take the string and tie the fork to the centre of the string/thread.
2. Take one end of the string/thread and tie it around your right index finger (pointer), then tie the other end of the string/thread around your left index (pointer) finger.
3. Place your fingers (index/pointer) to your ears and let the fork dangle in front of you.
4. Get someone to tap the fork with the spoon. You should hear loud ringing in your ears.
The ringing sound travels up the string/thread to your ears.
You could tie other metal objects to the string/thread to see what sounds travel to your ears.

MUMMIFICATION PROCESS... Discover how the Ancient Egyptians used drying as one step
 
#1 EXPERIMENT: FISH MUMMY
Need:
l raw fish from the market
Two boxes of baking soda
Kitchen scale
Plastic container with a lid
1.  Weigh the fish on a kitchen scale.
2.  Coat the fish inside and out with baking soda, and bury it completely in baking soda in the plastic container. Let it sit this way for a week in a cool shady place (in a refrigerator, if you like).
3.  After a week, take it out, dust it off, and weigh it again. Re-bury it in fresh baking soda, for another whole week.
4.  Take it out and weigh it once more.
What does the fish look, feel, and smell like?

HOW’S IT WORK?
Baking soda acts as a preservative and drying agent. The weight loss you noticed is due to the removal of water by the baking soda. Drying the fish is essential to making it a mummy. What happened after the first week? After the second week?

Notes from a boy who did it…Jordan, 6th Grade, NY
I
tried the experiment called "Fish Mummy" On the first week when I took the fish out; the first thing I noticed was the smell. It smelled like the most disgusting thing you can think of. I described it as rotting eggs. The next thing I noticed was what it felt like. It was kind of stiff. I thought that it would have felt like Jell-O. On the second week that I took the fish out the smell wasn't as strong as usual. It didn't smell as bad.

PROJECT #2: MUMMIFIED APPLE
You Need:
1/2 apple
1 Popsicle or craft stick
1 medium-sized plastic bags that seals
Natron Solution: 1/4 cup table salt, 1/2 cup sodium carbonate (powder bleach), and 1/2 cup baking soda; Stir together--this makes enough to do one apple. You may maximize this recipe as necessary.

TO DO AND OBSERVE

  • Make the Natron solution (recipe above) in the plastic bag.
  • Carve a face into the apple with the Popsicle stick then stick the Popsicle stick into the apple so you have a handle (like you were making a candy apple).
  • Dip the apple into the Natron Solution until the face is covered, and leave the apple in the bag.
  • Safety precautions: Do NOT eat the apple or the Natron Solution; wash your hands after the activity and don't touch your eyes or mouth until you wash your hands. You might want to wear plastic safety goggles. Leave the bag open in an upright position to allow air to flow.

Record your observations as your apple mummifies. What happens to the apple once it is covered with the Natron Solution? How much time does it take for the apple to turn into a "mummy"?  (The mummification of the apple may take up to two weeks. Source: tryscience.org

SINK OR FLOAT...

CAN YOU SINK AN ORANGE?
You will need: A Bowl, Water, and an Orange
1.  Fill the bowl with water.
2.  Put in the orange...What happens to the orange?  See if you can get the orange to sink.
3.  Take the orange and peel it.
4.  Place the peeled orange back in the bowl of water. What happens this time?
5.  The orange sinks because the orange peel if full of trapped air pockets, therefore making the orange light for its size (so   it floats).
6.  When you remove the peel (including the air pockets) the orange weighs a lot for it.

Along with the above experiment try a ‘Sink or Float with a Pumpkin or Watermelon!

  • Fill a bin or aquarium or tub half full with water. Place everyday items near the bin. Get the kids to guess which items would sink and which ones would float. Have youth write their guesses in their notebooks. Then do the experiments to determine if they were right or not.
  • Be sure to add a watermelon to the guess! (You can eat it afterwards!) Pumpkins are also fun. The pumpkin and watermelon will float because its mass is less than the mass of water it displaces. This is due primarily because the inside of the pumpkin and melon are hollow. It is mostly air, which has a much lower mass than water.

________________

CATCH AN ICE CUBE
Need: Ice cubes, cup of water, string, salt
1.  Float an ice cube in the cup of water.
2.  Carefully lay one end of a piece of string on the floating cube.
3.  Sprinkle a pinch of salt onto the string and wait for about 30 seconds.
4.  Pick up the string, and WOW, you caught an ice cube
5.  But what else can you use besides salt? Try sugar, pepper, sand, flour, you name it. See what works, and what doesn't, and try to figure out why!
How's it work?
Salt that dissolves on the ice cube lowers its freezing point, which means that it actually melts faster than normal in the cup. After some of the salt washes away, a little bit of the water on the cube re-freezes, trapping the string with it. Substances that dissolve in water can lower the freezing point of ice, while things that don't dissolve can't.

From Jacy, age 12, MN (Catch an Ice Cube)
First I collected the materials that were needed. When I started with the salt and ice, I found that the salt melts the ice and then it refroze over the string. You could then lift up the string and the ice cube would be hanging from it. I tried doing this experiment with other substances like sugar, pepper, baking soda, and baking powder. I found that none of them worked like salt did to make the string stick to the ice cube. The experiment was cool.

THREE CHRYSTAL EXPERIMENTS
 

#1 CHRYSTAL SHAPES
NEED: Epsom salt, a tablespoon, a cup of water, a paper circle, a jar lid
1.  Cut out a paper circle the same size as the jar lid. Put the circle in the lid.
2.  Measure 4 big tablespoons of Epsom salt. Don't worry if you add too much - the more, the better.
3.  Dissolve all 4 tablespoons in the water and stir the mixture thoroughly.
4.  Pour the water mixture into the jar lid. Stick the lid in a place where it won't be disturbed. It will take a few days, but let the water evaporate and see what happens!

HOW’S IT WORK?
In a few days, the water will evaporate from the lid. But the Epsom salt will be left behind. The salt will build up into its own unique crystal shape. You can make a miniature rock forest.
Source: pbskids.org
_____________________
#2 CHRYSTAL GARDEN
Materials: Water, Alum (found in the spice section of supermarkets or drugstore), Clear glass bowl, Clean rocks and pebbles
1.  Bring 1/2 cup of water to a boil.
2.  Add 2 ounces of alum, stirring until the alum is dissolved.
3.  Pour the solution into a clear glass bowl half filled with assorted clean rocks and pebbles.
4.  Within hours you should be able to see alum crystals forming as glass-like squares. Within several days you should have a number of crystals to look at.

______________________
#3 CRYSTAL SNOWFLAKES
1.  Cut a white pipe cleaner into 3 equal sections and twist it together to make a six-sided flake.
2.  Tie a string from point to point to form the pattern.
3.  Also, tie a piece to the top of one of the pipe cleaners and tie the other end to a pencil (This is for the snowflake to hang from)
4.  Fill a wide mouth jar, cup or glass with boiling water.
5.  Mix in Borax one tablespoon at a time (3 Tablespoons per cup of water) and stir it until it’s dissolved. (It’s alright if there is some settling.)
6.   If desired, add a little blue food coloring at this point to tint the snow flake.

Totally immerse the snowflake in your solution. Rest the pencil on the top of the container letting the flake suspend freely in the solution. Wait overnight and the next day the children will have a snowflake covered with tiny crystals.

CRAFTY Science...This one is fun!!!! (Image by KidActivities.net)

TOOTHPICK TOWERS...Made using Cheese Puffs, Tootsie Rolls, Tooth Picks and Gummy Bears

1.  Prepare large Ziploc bags with kids' names written on them.
2.  Put small Ziploc bags inside the large ones.
3.  Fill one small bag with about 100 toothpicks, another one with Tootsie Rolls, another one with Cheese Puffs, and the last one with Gummy Bears.
4.  The kids' task is to BUILD THE TALLEST, MOST STABLE STRUCTURE, using the materials provided. (The structure in the image is 19"...the kids (my grandchildren 9 and 12 also decided to use a few mini-marshmallows.)

EXTENSION IDEA:
You can have the kids make structures that resemble molecule shapes using the same materials. The activity then becomes "Make a Molecule Center." NOTE: I saw my image of this activity posted awhile back on Pinterest. The description said it "...was made with sausages!" No, no, no... Lol! (Barb)

________________

MAKE PAPER FROM TOILET PAPER!
Materials:
Toilet paper (use an inexpensive brand – the coarser the better)
Empty plastic water bottle
Kitchen strainer
Large dry sponge
Old newspapers
Rolling pin
Waxed paper
Food coloring (optional)

1. First of all, make sure you have plenty of working space for this activity. Cover a table with newspaper to limit the mess.
 
2. Place 10 squares of toilet paper in the water bottle. Fill the bottle half full with water and close securely. If desired, you can add a few drops of food coloring to the bottle to create colored paper.

3. Have children count to 100 as they shake the bottle. This shaking will allow the toilet paper and water to make pulp.

4. Once the mixture looks like “slush”, the pulp is ready. Pour the pulp into the strainer in a thin, flat layer. Squeeze as much excess water out of the pulp as you can.

5. Prepare a working space with layers of newspaper to absorb the water. Without moving the layer of pulp with your hands, flip the strainer and let the pulp fall onto the layer of newspaper. Cover the pulp with a piece of waxed paper and use the rolling pin to squeeze out any excess water. Remove the waxed paper and place the sponge on the paper to absorb the excess water. You may have to repeat this process several times.

6. Once you’ve removed all of the excess water, allow the paper to dry overnight. The children now have their own piece of handmade paper. They can decorate the paper the next day, use it to write a note, or make a gift tag or pin. Be creative!

TRY MAKING... AN ERUPTING VOLCANO...

Note: K-A made version #1 with grandsons 'N' and 'B'. Although the boys thought the experiement very cool, we would make the 'mountain' itself differently next time. The 'dough' material didn't want to easily stay on the bottle. After adding more salt, water and oil--we were able to make a mountain of sorts. Repeating this activity, we would use a different play dough or  modeling clay.

To the delight of the boys (ages 8 and 12), the volcano erupted for quite awhile. K-A has also successfully made volcanoes with the other methods.

Additional Note: 'N' thought it would also be cool to add adventure seeking climbers to the mountain. Hence, the 'dark blobs'--aka  gummy bears-- on the face and bottom of the hill! Barb

#1 Version VINEGER VOLCANO

This is a classic science experiment, and an easy one. To make the volcano, mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The mixture should be smooth and firm.

Stand a large soda bottle in a baking pan or shallow dish, and begin to shape the dough around it. Don't cover the hole and don't drop any of the dough into it. Fill the bottle about three-quarters full with warm water and a few drops of red food coloring. Add 6 drops of liquid detergent to the bottle, and 2 tablespoons of baking soda.

Slowly pour vinegar into the bottle and step back!

#2 VOLANO

  • Fill a child’s swim pool or sandpit with lots of slightly moist sand.
  • Get the kids to each make a volcano sand mound with a hole in the center
  • Place a small disposable cup in the hole; put in 1 tablespoon of baking soda plus 2 tablespoons of water in order to make it dissolve.
  • Add 2 tablespoons of vinegar to which you have added a few drops of red food coloring, then watch it erupt!
    You can repeat the activity over and over again.

VOLCANO #3

1.  Before the eruption event, form a piece of modeling clay about the size of a baseball into a mountain shape.
2.  Put the shape on waxed paper.
3.  Using your fingers, pinch the sides of the clay to form lumps that look like lava coming down the sides of the volcano.
4.  Poke a hole in the middle of the volcano. Let the clay dry overnight.
5.  Paint the volcano with brown paint. Let the paint dry thoroughly.
....To make your volcano active: Put 1 tsp of baking soda in the center of the volcano. Then add 1 tbsp of vinegar to make it erupt. Watch out!

Volcano #4  Materials you will need: 

 1/4 Cup of Vinegar 
 Red Food Coloring 
 Liquid Dishwashing Soap 
 1 Tablespoon Baking Soda 
 Modeling Clay (Plasticine) 
 Newspaper or Vinyl Table Cover
     Steps
1. Clear a work surface and cover it with newspaper or a vinyl table cover.
2. Model a volcano out of modeling clay. You could use red clay around the top of the volcano to make it look like red-hot lava. 3. Make a hole at the top of the volcano.
4. Stir in 1 tablespoon of baking soda
5. Add a few drops of red food coloring
6. Add a few drops of liquid dishwashing detergent.
7. Get ready! Pour in ¼ cup of vinegar and stand back!!!
The eruption is acid meeting another substance called an alkali.

DANCING POPCORN

Fill a clear cup  3/4 full with vinegar.  Add 1/2 teaspoon baking soda. Drop in a few kernels of unpopped popcorn.  Watch as the kernels rise and fall.
Variations: Try substituting club soda for the vinegar and baking soda. You can also try using other objects like buttons or pebbles.

ACING POWDER

  • Fill a shallow dish with water.
  • Sprinkle talcum powder over the surface of the water.
  • Dip a toothpick into Dawn dishwashing liquid.
  • Dip the toothpick into center of water in pan.
  • Watch the powder race to the sides of the pan.
  • Variation: Try this same experiment with pepper instead of powder.

MOLD GARDEN #1


For some reason children seam to love watching mold grow. Here is a safe way to experiment with mold.

 

  • Give children a small zip-lock bag and a piece of bread.
Have them place the bread into the bag and then add a teaspoon of water. Zip up the bag and set out the bag to observe. After a few days, mold will appear on the bread.

  • Discard bags unopened, when experiment is over.
Variation: You may want to repeat this experiment, but this time make two bags of water and bread and put one in the center and one in the refrigerator. Which one grows mold the fastest?

______________

GROWING MOLD #2
Materials you will need:
Water
Some tape
Some leftover foods (like bread, oranges, lemons, apples, grapes, red peppers, courgettes, cauliflower, cheese or biscuits)
A Clear Container with a Lid (A big glass jar or a big clear plastic container works best)
*** DO NOT USE: anything with meat or fish in it. After a few days these would start to smell very bad.***

NOTE: This is a great project to keep a log or notebook on your findings each day that you check for changes.
Steps:
1. Place the jar on its side.
2. Cut around 3 to 5 different pieces of food into small chunks about 1.5cm (1 inch.).
3. Dip all the different pieces of food into the water.
4. Spread the foods out in the jar so that they are not in a pile.
5. Place the lid on the jar and tape around the outside of the lid to seal it
6. Place the jar where it will not get knocked over or thrown away.
7. Put a label with the date on the jar
8. Keep a check on the food in the jar.

  • You probably won't notice any change in the food for the first few days; however, you should start to see some green, white or blue fuzzy/furry stuff growing there after.

  • Still keep checking; after a few more days some of the food may start to rot and look gross. Now you can see how the mold spreads and how the food rots in just two weeks.

NOTE: After the two weeks, DO NOT open the lid. Throw the jar and its contents in the bin and DO NOT reuse the jar.
Molds do not grow from seeds. Molds grow from tiny spores that float in the air. Some of these spores fall onto a piece of damp food and then grow into mold. Adapted from: kids-science-experiments.com

FINGER PRINT LIFT: Here's an amazing trick that lets children try their hands at a little forensic science by lifting their own fingerprints.
1.   Individually, have each childe press their fingertip on a pocket mirror.
2.  Cover the entire print with graphite dust by rubbing a soft pencil with sandpaper.
3.  Blow gently to remove excess dust.
4.  Now carefully stick a strip of tape to the print and slowly peel it off. Stick the tape to a piece of white paper, and the print should be distinct. You can inspect the fingerprint under a magnifying glass, or just with the eye.  If you go to the wiki website, I you can decide whether the fingerprints are 's' whorl, loop, or an arch.

_______________

 ACID & BASE EXPERIMENT

1.  Before the science event, boil 1 cup of shredded red cabbage until the water is dark.
2.  Dilute it with water until medium purple.
3.  The purple water will show if something is an acid or a base.
4.  If the water turns light green or yellow color (after adding the substance), then the substance is an acid. And if it turns dark green or blue - it is a base.
Divide this liquid solution in several glasses. Have the kids guess what color the water will turn. Add baking soda (turns green), bleach (turns yellow), sprite (turns light purple), etc. Get litmus paper to check the acidity levels.

MAKE A 'NAKED EGG'--EGG IN VINEGAR EXPERIMENT (K-A tested; image by K-A)

  A naked egg is an egg without a shell. Using vinegar, you can dissolve the eggshell--without breaking the membrane that contains the egg.
 
Materials:
Eggs  
White vinegar
A container big enough to hold all the eggs; a cover for the container
A big spoon 
   
1. Place eggs in the container so that they are not touching.
   
2. Add enough vinegar to cover the eggs. Notice that bubbles form on the eggs. Cover the container and put it in the refrigerator. Let the eggs sit in the vinegar for 24 hours.
 
3. Using the spoon, scoop the eggs out of the vinegar. Be careful--the eggshell has been dissolving. The egg membrane, which is not as durable as the shell, may be the only thing holding the egg together.
 
4. Carefully dump out the vinegar. Put the eggs back in the container and cover them with fresh vinegar. Leave the eggs in the refrigerator for another 24 hours. 
   
5. Scoop the eggs out again and rinse them carefully. Throw out the eggs where the membranes have broken and are oozing out. 
   
6. When complete, there will be an egg without a shell. It looks like an egg, but is translucent. The membrane will flex when squeezed.
   
E
XPLANATION:
An eggs shell dissolves when submerged in vinegar.
Vinegar contains acetic acid, which breaks apart the solid calcium carbonate crystals that make up the eggshell-- into their calcium and carbonate parts.
The calcium ions float free (calcium ions are atoms that are missing electrons), while the carbonate goes to make carbon dioxide.(Those are he bubbles that you see)

Note: The shell dissoled in 24 hours. Although directions say to put the egg in the refrigerator, I forgot to. (It still came out fine) The remainder of the experiment was followed as directed. After a couple days, you could actually see the yolk floating within the membrane. Both kids and adults liked this one! The egg feels rubbery--but it does 'splat' when dropped. Barb

_______

 

  THE ABOVE EGG EXPERIMENT--EXCEPT USING A 'HARD BOILED' EGG!

Directions are exactly as used in the above "Raw Egg" in Vinegar experiment... except you first boil the egg and let it cool.

The shell dissolved within 24 hours--the same as in the above experiment. I left the egg in the vinegar for a couple days to see if it would become transparent as when using the 'unboiled' egg. It did not.

What it did do was become bouncy. (See image as it bounced to and off the floor) Trying to get a good photographic image, the egg was literally dropped about 25 times from heights of up to four feet. The egg did not break but bounced after each drop.  

The difference between the two egg experiments would be interesting for the children to observe and talk about. (Image by KidActivities.net)

 This is science, art, and outside winter play!

ICE BLOCK DESIGNS

Younger children can observe how salt melts ice while creating colorful designs in large blocks of ice.
Need: Large blocks of ice, Coarse salt, Food coloring, Eye droppers

Freeze water in empty one gallon milk containers. Remove the cardboard when water is frozen.

  • Place ice blocks on trays covered with several layers of newspaper.
  • Sprinkle coarse salt on top of the ice blocks.
  • Drip various colors of food coloring on top of the ice block--tunnels of color are created as the salt melts through the ice block.
  • Put the colorful ice blocks outside. If cold enough- they should stay frozen for several days.
  • Children can continue to examine the melting process during outdoor play. If possible-(and if they are interested) give kids their own block of ice.
  • If you have a large group do this activity over a few days. Children will enjoy watching the changes that occur as the blocks melt away!(Image by KidActivities.net)

Idea dapted from Marjorie E. in KinderArt.com NOTE: When salt goes over the side of the ice block-it will quickly melt grooves into the sides. The color will travel down the grooves. KA placed the ice block in a tin pie pan with lots of paper to soak up excess colored water. The ice stayed solid (outdoors) for about a week. (It melted when we had a freakish 65 degree Michigan winter day in January!)

Decorating a Mad Science Lab

June 7, 2009 21:48 by Barbara Shelby

 

Make one party room/area into the lab. It will be much easier to decorate and will contain 1. On the entrance to the room-- put up some danger tape and a notice warning that only scientists may enter the "Secret Science Lab Zone".

 2. Using black construction paper cut out large question marks, magnifying glasses and mathematical formulas. Put these up around the room.

3.  Put up posters of famous scientists around the room with a small caption underneath of why they are famous.You could also hang some science clip art pictures in the room. These can be found with an internet search such as Google.

4.  Decorate the space with an array of lab items such as gummy frogs that have been pinned down so that they look as if they were being dissected. You can also keep jars of lab specimens such as huge gummy snakes, lizards etc.

 5. Check out Halloween stores/sites/for slimy table decorations which are perfect for scientists; also skeletons, skulls and other gory accessories. If you're going for a spookier look--purchase cobweb/spider webs from Halloween stores and put them about the room on tables, etc.

 6.  A dry ice machine would make a great table center piece.

 7. Fill lots of different shaped jars with colored water and rubber body parts to put around the table.

 8.  Borrow microscopes, chemistry sets, molecule models, magnifying glasses, compasses, and so on, and place them on the table and about the room. Do you have a flickering plasma lamp? Kids of all ages love them!

 9. Use a colored globe light to give the room an eerie appearance or just place colored light bulbs in regular lamps.

10. Set up a large chalk board/white board and write the recipes for the experiments that you are going to do.

 11. Hang a sign from the table or at the doorway saying “Welcome to the Science Laboratory”.

 12.  Use a 'weird or scary font' to write signs such as "Electricity", "Gas", "Chemicals", and put them around the area.

13. Put a rubber band around several large test tubes. Tie a ribbon over the rubber band. Arrange tubes to stand with open ends up. Fill them with colored water and add a flower or two.

14. Make a Light Bulb Pinata--Click here for directions! (And Photo)

MAKE LAB COATS 

 #1 Professor X Lab Coats: Cover the table with newspapers or freezer paper. Lay out fabric markers. Give each child a plain white shirt to decorate as a lab coat. You can use T-shirts, or look for used front-buttoning shirts at thrift shops

Idea #2
Use white kitchen sized garbage bags to make lab coats
(A practical way to protect children's clothing during experiments)
Cut a half circle hole for the head, and half circles for the arms. With a black permanent marker, draw a line down the front and buttons next to it. You can also draw a pocket on the side with a pen in it; write the children’s names on them (Example: Professor Smith, Dr. Susan.

_________________

JUST LIKE EINSTEIN
Purchase black party glasses with the noses and mustaches from a novelty or party store. Before kids enter the “science lab” have them don their coats and glasses. It would be great if party facilitators could be wearing white lab coats, crazy wigs, goggles, or glasses too! BE SURE TO TAKE PHOTOGRAPHS of this
! Kids may not leave these on long---but it will be great fun.

DECORATE WITH DRY ICE ...

SMOKEY CAULDRONS

For truly dramatic effects, create fog using dry ice. Add one piece of dry ice to every gallon of very hot water. Note: Be careful and make sure that it is in a place where children cannot hurt themselves. (See complete directions below)

Also check out the HALLOWEEN DECORATING PAGE  for a "Spooky Jack-O- Lantern" with Dry Ice Fog.

 __________

CREATE A 'FOG EFFECT' with dry ice
 
Materials needed:
Large container
Lot water
Lry ice
CAUTION: Only use dry ice in a well-ventilated area. The carbon dioxide released from dry ice will displace oxygen.
 
Fill a metal or plastic container half full with hot water, add a few pieces of dry ice every 5 to 10 minutes. As water cools, it will be necessary to start over with hot water to maintain the fog effect.

As a rule of thumb, one pound of dry ice will create 2-3 minutes of fog effect. The hotter the water, the more fog but the quicker dissipation of the dry ice.

When you place dry ice into some warm or hot water, clouds of white fog are created. This white fog is not the CO2 gas, but rather it is condensed water vapor, mixed in with the invisible CO2. The extreme cold causes the water vapor to condense into clouds. The fog is heavy, being carried by the CO2, and will settle to the bottom of a container, and can be poured. You can produce enough ground - hugging fog to fill a medium-sized room with a pound or so of dry ice. Do not allow anyone to lie down in this fog, or allow babies or pets into it, as CO2 gas does not support life. Source: continentalcarbonic

DECORATE WITH PLASMA LAMP

Whether you call them nebula spheres, PLASMA LAMPS, or lightening balls, these lamps put on one of the most unique displays available. Twenty years ago they cost $1500. Today you can get one for $40.00 or less...
Technically, they're a clear glass orb, filled with a mixture of various gases at low pressure, and driven by high frequency alternating current at high voltage...Great for decorating a 'Mad Science Lab'!!!
