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!
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.
Listen to your heart beat by making your own Stethoscope.
Make a model of a human brain using playdough.
Learn about keeping your hands clean with this fun glitter activity.
Discover the relationship between arm span and height.
Human Body Science for Primary School
Use eggs to learn about tooth decay. Soak them in vinegar, coffee and coke to see what happens to the shell.

Did you know you can test your reaction time using just a ruler?
Have some fun finding out how strong your bones are.
These printable organs from Adventure in a Box are just brilliant!
See a close up of your fingerprint using a balloon!
