    Science Experiments for Learning about the Human Body

    March 17, 2021 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.

    Listen to your heart beat by making your own Stethoscope.

    Make a model of a human brain using playdough.

    Learn about keeping your hands with this hand hygiene activity.

    Discover the relationship between arm span and height.

    Human Body Science for Primary School

    Did you know that taste is linked to smell?

    Use eggs to learn about tooth decay. Soak them in vinegar, coffee and coke to see what happens to the shell.

    Materials for staining eggs

    Investigate heart rate. This can be done by recording your pulse rate at rest then doing some exercise and measuring it again.

    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!

    Find out why you get dizzy with this great guest post from Red Ted Art

    Learn about your lungs with this fake lung experiment.

    Human Body Science for Secondary School

    Make a model of a pumping heart using a jar.

    Make a model of an animal cell. An edible version is especially fun!

    Jelly Animal Cell Model - great for learning about cell structure

    Another easy edible experiment is my candy DNA model!

    Follow the journey of food through the digestive system with this easy activity using tights!

    These edible neurons from My Mundane and Miraculous Life are just brilliant too!

    Find out how you can ‘see sound’ with these easy sound activities.

    Try some of these brilliant blood experiments for learning about the heart, circulatory system and red and white blood cells.

    Link to a scientist

    Marie Curie‘s research into radiation led to the discovery of radium which is now used to treat some cancers.

    Marie M. Daly did groundbreaking research in the relationship between high blood pressure, cholesterol and clogged arteries.

    Can you think of any more human body science experiments for us?
