Junior Scientists: The Human Body Series

Learn about the heart, bones, digestive system and brain during a four-part virtual series full of at-home fun for the whole family!

Are you ready to turn your kitchen into a laboratory? Prepare your materials, grab your notebooks and join the Science Centre on Zoom for Junior Scientists: The Human Body Series.

This engaging new program includes four 90-minute sessions broadcast live from the Ontario Science Centre. Examine a different system of the human body each week through live demonstrations, at-home lab activities and fun crafts using simple household materials. Make your own stethoscope, try your hand at testing pipe-cleaner joints, snack on crackers (for science!) and test your skin’s sensitivity to touch—plus so much more!

Separate Junior Scientists programs are available for children ages 5 to 7 and 8 to 10, but there’s no age limit on science! With only one registration required per family, this program is a great opportunity to spend time learning and playing together.


Junior Scientists: The Human Body Series is a four-week program composed of virtual 90-minute sessions. This program is being offered twice in early 2021, with limited spots available for each set of dates. Participants will register once for all four sessions of the program:

Option 1: Sundays, January 17 to February 7

· Ages 5-7 — 9 to 10:30 a.m.
· Ages 8-10 — 11 a.m. to 12:30 p.m.

Price: $105 including HST, $95 for members (Planetary, Stellar, Galactic or Cosmic levels only)

As with all virtual Science Centre programming, adult supervision is required for Junior Scientists sessions. Participants will be able to ask questions and engage with Science Centre staff using the chat function of Zoom.

Event capacity is limited, and registration will be available on a first-come, first-served basis. After you have registered for Junior Scientists: The Human Body Series, you will receive a Zoom link, activity PDF and materials list for each session via email at least one day in advance.

Program Schedule

Week 1: How the Heart Works

Learn how the heart pumps blood, and find out why eating healthy foods and staying active can help prevent heart disease. Then, make a stethoscope from household items for the final part of this week’s session: a heart rate investigation lab.

Week 2: How Bones, Muscles and Joints Work

Take a close look at bones, muscles and joints, including why bones change, what muscles do and how joints work. Examine X-rays, then engage in an interactive lab about joints. Finish the session by making your own functional hand model using household materials.

Week 3: How the Digestive System Works

Get the breakdown on how food travels through the digestive system, how the body stores nutrients and how it gets rid of waste. Examine the different parts of the digestive system and watch a mock demonstration about how stomach acids react to food. Grab a snack for a food-testing lab, and then put your new knowledge to work to create a digestive system diagram.

Week 4: How the Brain Works

Uncover the science of thinking and so much more. Test your reflexes to learn about neurons, and watch a demo to see how these cells transmit signals to the rest of the body. Finish this exciting session by making your very own memory game—and don’t forget to challenge your family members to a match later!
