I love science! I love doing experiments with my kids at home and teaching science at school. Children are naturally curious about the world around them and are eager to explore. The amount of learning and excitement that happens with a great experiment makes me very happy. I have collected over 80 science experiments for kids to try out at home, or in the classroom.
My main goal with science experiments are to encourage a love of science and learning in the children who do them. Most of the ideas in this collection are simple hands-on experiments that explore scientific concepts in kid friendly ways.
The experiments may not always work out perfectly every time, but that is a huge part of science and experimenting.
Search through the list to find the perfect experiments to try at home or in your classroom today. I hope that you have as much fun as we do with the experiments!
Most of the science experiments below use kid friendly materials and hands-on exploration. However, as with all science experiments, adult supervision is necessary at all times. Make sure to choose activities that are appropriate for the age and abilities for the children you are doing the experiment with.
