Curious kids turn into junior scientists with these fun and simple science experiments for kindergarten. Science doesn’t need to be difficult or complicated for our younger kiddos! Here’s our list of the best kindergarten science activities that are totally doable and use simple supplies for home or in the classroom.



There is much you can teach your kindergarten age kids in science. Keep the activities playful and simple as you mix in a little of the “science” along the way.

These science activities below are also great for short attention spans. They are almost always hands-on, visually engaging, and filled with play opportunities!


Not only are these science activities an awesome introduction to higher learning concepts, but they also spark curiosity. Encourage your kids to ask questions, problem solve and find answers.

Science learning in kindergarten encourages young kids to make observations with the 5 senses including sight, sound, touch, smell, and sometimes even taste. When kids are fully able to immerse themselves in the activity, the greater the interest they will have in it!

Kids are naturally curious creatures and once you have piqued their curiosity, you have also turned on their observation skills, critical thinking skills, and experimenting skills.

Kids will naturally start to pick up on the simple science concepts presented just through having a fun conversation about it with you!
