Fun & Easy Science Experiments for Kids

Instructor: Shelby Golden
Use these fun experiments to help get kids excited about studying science. Check out our easy-to-follow directions to get ready to have a great time learning.

Reaction Volcano!

This fun, easy and messy experiment helps get kids familiar with chemical reactions.

You'll Need:

  • 10 ml soap
  • 100 ml cold water
  • 400 ml white vinegar
  • Baking soda
  • 2-liter plastic bottle

What to Do:

Have your students mix their soap, water and vinegar in the bottle. Next, students should fill a separate cup about halfway with baking soda. Add extra water to this cup to fill it up. Mix the baking soda and water until smooth. For the rest of this experiment you'll probably want to step outside!

Your students need to pour the baking soda mixture into the bottle. Make sure they pour quickly and then get out of the way as the bottle will quickly erupt!

This experiment features a chemical reaction between vinegar and baking soda that creates carbon dioxide. You can expand this experiment by having students experiment with using different amounts of water, vinegar or baking soda!

Quick Tip

Your students can keep learning about this topic with fun video lessons on types of chemical reactions. These lessons are engaging and short enough to keep students' attention! They each feature quizzes you can use to check how well they understand the concepts.

Making Layers

Use this experiment to help students learn about density while having fun.


  • Clear glass
  • Water
  • Oil
  • Corn syrup


Your students should begin by pouring ½ c. of water into the glass. Next have them add ½ c. of the syrup. Have your students record what happens to syrup. Does it mix together, or float? It should sink and form a layer on the bottom of the glass. Finally, have your students slowly add in ½ c. of oil. The oil floats on top of the water!

All of these liquids have different densities, so instead of mixing together, they form layers on top of one another. Explore this further by having students add the liquids in a different order, or even stir their layers around. Do the liquids stay mixed, or do they separate out again?

Quick Tip

Help your students keep building their understanding of this concept with this lesson on density. This lesson helps reinforce what students learned through the experiment and keeps them building their scientific knowledge.

Candy Solution

You can have students complete this experiment for a sweet way to understand solutions.

Get These Supplies:

  • String (about 6 in. long)
  • Popsicle stick
  • Paperclip
  • Around a cup of water
  • 2 cups of sugar
  • Mason jar

Follow These Steps:

Instruct your students to tie their string around the middle of their popsicle stick. They should attach the other end of the string to the paper clip. Have them place the stick over the mouth of the jar, allowing the string to hang down. It should be close to (but not touching!) the bottom of the jar. Once your students are sure the length is right, have them remove the stick and set it aside.

Next, your students are going to need to boil some water. Each student will need about 1 c. of water to bring to a boil. Have them dissolve sugar at ¼ c. at a time, stirring consistently until they've mixed in about 2 c. of sugar. Once the solution is good (all hot and very sugary!) have students carefully pour the liquid into the jar. They should place their stick back over the jar, lower the paperclip, and put the jar somewhere safe to cool down.

The final step of this experiment takes a few days! Have students check out their jars every day as a crystal grows inside. Eventually the sugar will not be able to remain in the solution and will instead form sugar crystals around the string. After a few days students can pull it out and see how delicious science can be!

Quick Tip

Have your kiddos watch lessons on chemical solutions to learn more about different types of solutions and come up with some new experiment ideas. Use the quizzes in each lesson to reinforce what they're learning while performing the experiments.
