20 Teacher-Tested Science Projects for Kids

1. Frozen Powers

Whether or not your kids like Disney’s Frozen, these icy experiments are sure to earn you a “cool” parent award.  Watch the instant transformation from a liquid to a solid right before your eyes by simply dipping a finger in shaved ice and then into your glass of nearly frozen purified water.  Even Anna and Elsa would be impressed with this frosty experiment!

2. Glow in the Dark Bouncy Balls

Using some fluorescent paint and a Borax base, these easy-to-make bouncy balls are sure to be a “highlight” with your kids.

3. Make Dry Ice Bubbles

This is an experiment for some serious scientists.  However, although it does require some specialized equipment and set up, the outcome isn’t going to be popping anyone’s bubble any time soon.  Check out Not Just Cute for a great tutorial for set up and tips.

4. Magnetic Slime

Help your little scientists learn about forces and motion with this slimy experiment.  You’ll need some really strong magnets and specialized iron oxide powder, but the payoff is worth the effort to get the materials.  For hours of oozy fun, slide on over to Frugal Fun 4 Boys for directions.

5. Rain Cloud in a Jar

Have your curious meteorologists ever asked how clouds produce rain?  What better way to help them visualize the process of precipitation with this easy to do rain cloud in a jar? From Coffee Cups and Crayons.

6. Make Lightning

What an electric experiment as a follow up to the Rain Cloud in a Jar investigation!  Shock your kids with this experiment using static electricity.  All you need is a pencil, an aluminum tray, wool cloth, a styrofoam plate, and a thumbtack.

7. Hovercraft

With all the hype in recent years about drones, your kids will be certain to float with delight when you show them this experiment. Teach your children about the laws of motion and gravity using just an old CD, a water bottle spout top, a balloon, and some superglue.  Instructions provided by Scribbit.

8. Walking On Eggshells

No need to worry about walking on eggshells with this investigation… that’s the whole point!  Grab 2-6 dozen eggs, a black plastic bag (just to be safe), take off your shoes, and watch how the seemingly fragile shells can actually withstand a surprising amount of weight.  What’s the secret?  The egg’s arched shape gives it tremendous architectural support.  For more details on conducting this sturdy experiment, check out Steve Spangler Science.

9. Rock Candy

Here’s a sweet way to teach children about states of matter and chemical reactions.  Set up and assembly is easy enough, but do be prepared for this scientific observation to take some time (up to about a week!).  Once the crystals have formed though, kids are in for a rockin’ time!

10. Solar Oven

You don’t need a campfire to enjoy some tasty s’mores with this hot experiment.  These easy-to-assemble solar ovens provide layers of sticky learning all about heat and energy transfer.  Refer to the assembly instructions here.

11. Rocket Eggs

It doesn’t have to be Easter time for you to take advantage of this EGG-cellent experiment!  Head outside with a plastic egg, some Alka Seltzer, and a bit of water to make some scientific observations (at a safe distance) about chemical reactions.  The Stem Laboratory gives all the details on their website.

12. Soda Geyser

Kidz World shows how to take some Mentos and bottled soda for an experiment erupting with fun and laughter.  The soda’s carbon dioxide and dimpled candy covering of the Mentos create a chemical reaction sure to have everyone shooting up with excitement and curiosity.

13. Weathering Rocks

Chemical weathering is the process by which rocks are decomposed by chemical processes.  Create your own simple chemical weathering observation with materials you likely have lying around the house (or out in the garden).  For an added learning opportunity, be sure to include a few different rock types to perform the Mohs Hardness Test.  Details can be found at Education.com.

14. Why the Ocean Doesn’t Freeze

Have your children ever been learning about Tundra habitats and wondered why the oceans in those regions don’t also freeze?  Here’s a nICE experiment for helping kids understand the process behind when and how oceans don’t freeze.  With basic kitchen ingredients, Education.com explains how to bring this investigation to life.

15. Effects of Sugary Drinks On Teeth

Want an EGG-stra effective way to show your children what sugary drinks can do to their teeth?  With this scientific observation of physical change, you’ll be certain to make your point about the importance of food choices and good hygiene.  Go to Feels Like Home Blog for more details and to keep those porcelains shining bright.

16.  Color Changing Flowers

Teach your kids about the plant kingdom and a process called transpiration with this colorful experiment.  You’ll only need a handful of white flowers, some small containers or test tubes, food dye, and a bit of water to bring this flower power to life.

17. Sound Vibrations

Did you know that with the right materials, you can actually SEE sound waves?  You’re sure to be in for some “good vibrations” with your kids using this observation lesson from Premeditated Leftovers.

18. Lava Lamp

For a groovy way to teach children about density, make these glass jar lava lamps.  In addition to the glass jar, you’ll only need some oil, water, food coloring, and a bit of Alka Seltzer to make this experiment one your kids are sure to “lava”.

19. Making Raisins

Understanding the difference between physical and chemical changes can be tricky for little minds.  This tasty experiment will sure make the difference easier to understand as you and your little one transform grapes into raisins.  Learn Play Imagine gives the easy-to-follow instructions here.

20. Ocean Layers in a Jar

Move over Pluto!  Outer space isn’t the only largely unexplored final frontier.  Oceans run so deep below the surface that humans aren’t physically able to explore all that this unseen world contains.  Help teach your deep sea divers about the 5 layers of ocean with this zonal observation in a jar.
