Discovery Bottles


Discovery and exploration in a bottle, set up your own science lab! Dr. Jean and Preschool Play constructed the bottles featured above. Below are the instructions:

1. Magnetism- Can a magnet work through plastic? What happens when you add water?
2. Static Electricity- Tear pieces of tissue paper and styrofoam. Then, rub the bottle on wool, your head, or the carpet. What happens?
3. Waves- Create waves and motion in a bottle. (1/2 cup corn syrup, drop of color, and glitter)
4. Bubbles- Mix up 1/2 cup water, drop of dish detergent, and food coloring. Shake, what happened? 
5. Mud- Can water and dirt make mud? (1/2 cup dirt, 2/3 full with water) Classify the water and the mud.
6. Sink / Float- What objects sink / float? (Beach Bottle in photo: Fill bottle with 3/4 cup sand, add water, drop of color, small objects, and a balloon.)
7. Numbers- Roll the dice and find the sum of the 2 numbers. Estimate how many objects are in the bottle.
8. Story- Put objects in a bottle and create a story from them!

Colorful Ice Sculpture Science

photo credit: art and creativity


Create colorful ice sculptures and see the science of mixing salt with ice! Art and Creativity shows how kids can make works of ice art by simply dropping liquid watercolor mixed with salt onto a chunk of ice! Science: Salt creates tunnels in the ice because it lowers the freezing point of water, causing the ice to melt. The colors make the tunnels pop, so we can see them better.

Also, check out We are Teachers to see how you can conduct this experiment with a large group of children!

Geography: Passport Please...


A fun geography project is to take your kids on a pretend trip around the world, to learn about other cultures and their history. Introduce kids to the food, music, geographic features, architecture, and language. Print out pictures and decorate your room to represent each country you visit. Send a stuffed animal around the world to different schools around the world, exchange souvenirs and postcards. For each country your animal visits, have his picture taken in front of a famous landmark or monument. To take the project even further, try to skype or ichat with schools from different countries. You can print out pretend passports and stamps, make airline tickets, and track your travels on a world map. Visit Making Friends for printable country fact cards. Note: You could also do this project nationally and learn about different states, corresponding with various schools from all over the U.S.

    Plastic Milk?!

    photo via Austin Kids
    Plastic Milk
    One cup of milk
    4 teaspoons of white vinegar


    how to:
    1. Heat up the milk until it's hot
    2. Pour the milk into a bowl
    3. Add vinegar to the milk and stir for 1 minute
    4. Dump milk through a strainer 
    5. Rinse the chunky milk in water and start molding it.
    6. After you have made a design you like, let it harden. Then, you can paint it.


    explanation: "When milk and an acid mix together, the milk begins to change properties. The milk begins to separate into a liquid and a solid. The solid material consists of minerals, fat, and a protein called casein. This protein is made of long molecules. Those molecules allow us to bend the lumps like rubber until it hardens and resembles plastic."  - AustinKids.org

    Rocket Reactions!

     First, make an explosion!



    Now, make a rocket with a film canister! Kids end up with a stellar toy that they can reuse!


    Science: "When you add the water it starts to dissolve the alka-seltzer tablet. This creates a gas call carbon dioxide. As the carbon dioxide is being released, it creates pressure inside the film canister. The more gas that is made, the more pressure builds up until the cap it blasted down and the rocket is blasted up."Science Bob (click here for instructions)

    Try this rocket from Steve Spangler, no film canister needed!

    Rainbow Glitter Crayons

    Don't throw those broken crayons away, recycle them!

    1. Preheat your oven to 275
    2. Spray a muffin pan with vegetable cooking spray
    3. Fill the muffin pin with broken crayons (mix and match shades and colors- whatever you would like!)
    4. Sprinkle glitter on top
    5. Bake for about 10 min at 275 (check on them)
    6. Take them out when they look melted through
    7. Next, use a toothpick and create swirls
    8. Let them completely cool down (you can put them in the freezer to speed the process)
    9. Finally pop them out (tap the bottom of the pan to help) and you're ready to draw!

    Blooms Recycled Paper

    Making paper out of recycled newspaper and old paper scraps is a great way to show kids how to be greener. For some extra fun and to be even greener, add flower seeds to your paper solution. When the paper dries, kids can plant their paper and watch their seeds grow. 
    1. You'll need to window screen/ frame for this
    2. Let all your scraps soak in water overnight
    3. Next, blend scraps in a blender
    4. Pour the scraps out and add water in a large, deep container
    5. Add flower seeds (Marigolds work really well)
    6. Dip your screen in and lift up
    7. Leave paper solution on the screen to dry overnight
    8. Once paper is completely dry, pull off of screen
    9. Cut your paper into squares and give to kids to plant!
    Plant your seeds in a cup, pot, or your backyard in soil. Make sure your seeds get plenty of sun and water.

    Colored Cubes

    The Colored Cube experiment is great for teaching kids primary and secondary colors. All you need is Sprite and colored ice cubes (2 red, 2 yellow, and 2 blue). Put a red and yellow cube in one cup, blue and yellow in a second cup, and red and blue in a third cup. Next, pour Sprite into all of your cups. Voila, kids see how primary colors mix in action! Below is an experiment my class conducted.

    EGG-cellent Experiments!

    Naked Egg - create a bouncy egg! Kids dissolve the shell away with vinegar!



    You made a naked egg, now what?! Shrink it and blow it back up again! You can also add black syrup and examine the inside!

    Featured above:
    Check out The h bar for lots of twists on the classic naked egg experiment!

    Rock Candy Science

    photo via math and reading help 




    Rock Candy Recipe, fun to watch and even more fun to eat! Below are two ways to create crystal candy!

    Method 1 - Science Bob
    materials:
    1 cup water
    2-3 cups sugar
    wooden skewer or chopstick
    clothespin
    jar or tall glass

    1. Pour 1 cup of water into a pot and bring to a boil
    2. Add 1/4 cup of sugar and stir until dissolved
    3. Slowly add more sugar and stir until dissolved
    4. Remove from heat and let cool for 20 minutes
    Optional - Divide solution into different bowls (the number of bowls depends on how many colors you would like). Add food coloring to each bowl (you can add flavoring as well if desired)
    Optional - Dip half of skewer into the warm sugar solution and coat with granulated sugar (let it cool completely so the sugar is adhered)
    5. Pour solution into your jar almost to the top
    6. Dip the skewer into the jar straight down the middle (not touching the sides). The skewer should be 1 inch from the bottom of the jar
    7. Clamp the clothespin on the skewer horizontal, so it lays on top of the jar to balance the skewer.
    7. Let the jar cool and place in a safe spot
    Watch the crystals grow!

    Method 2
    Note: Instead of using a skewer and clothespin, you can also try this method:
    - While sugar solution is cooling, take a pencil and tie cotton string to the center of it 
    Dampen the string with your sugar solution, then dip in regular sugar (let dry)
    - Pour sugar solution into your jar, suspend the string into the jar, and let the pencil lay flat on top
    - Cover the jar with a paper towel to keep it clean
    - Allow your crystals to grow 3-7 days

    Soap Souffle!



    Ivory Soap is the soap that floats! It contains air pockets. The microwave heats the air and water inside of it. The water vaporizes and the air expands, changing its physical state. You can conduct an experiment with Ivory Soap and another bar brand. Ivory puffs due to the air inside, while others will simply melt. (Microwave for 90 seconds to 2 minutes on a plate). Another experiment you can try is testing Ivory soap against another bar brand in a bowl of water. Ivory will float, while others will sink. You'll need 2 fresh bars of soap. Legend behind floating soap @ Ivory. For more science behind the experiment visit Steve Spangler!
