Science Experiments for Learning about the Human Body

July 28, 2020 By Emma Vanstone 31 Comments

This collection of science experiments for learning about the human body is perfect for encouraging kids to learn about their bodies! I’ve split the ideas into three age groups: preschool, primary age ( 5-11 ) and secondary ( 12+) but these are very loose recommendations. Hopefully you’ll find something that sounds fun to try!

I’ve also got lots of fun STEM challenges and science printable instructions you might like too!

Human Body Science Ideas for Preschoolers

If you have a big piece of paper or cardboard, get the children to draw around themselves, they can then measure arms and legs, label body parts or even draw in organs.

Learn about bones with this fun doctor role play activity using modroc as a cast on dolls.
