Junior Scientists: Space Exploration

A young child holds up a tablet showing a rocket.

Learn about astronauts, the solar system, comets, rockets and more during a four-part virtual series full of fun for the whole family!

Are you ready to explore the wonders of outer space? Join the Science Centre on Zoom for Junior Scientists: Space Exploration!

This engaging program includes four 90-minute sessions broadcast live from the Ontario Science Centre. Examine a different theme each week through live demonstrations, at-home lab activities and fun crafts using simple household materials. Experience “chicken legs” syndrome from home, build a model of our solar system, investigate asteroids and so much more—no spacesuit required.

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: Space Exploration is an online program composed of four 90-minute sessions. This program is being offered twice this spring, with limited spots available for each set of dates. Participants will register once for all four sessions of the program:

Option 1: Saturdays, March 27, April 3, 10 & 17

Option 2: Sundays, April 11, 18 & 25, May 2

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 all Junior Scientists sessions. Participants will be able to ask questions and engage with Science Centre staff using the chat function of Zoom, though cameras will be off for privacy reasons.

Event capacity is limited, and registration will be available on a first-come, first-served basis. After you have registered for Junior Scientists: Space Exploration, you will receive a Zoom link, activity PDF and materials list for each session via email at least one day in advance. To ensure each session begins and ends on time, please log on 5 to 10 minutes before your session’s start time.

Program Schedule

Week 1: All About Astronauts

What does it feel like to be an astronaut in outer space? To find out, examine a mock spacesuit, learn how changes in gravity affect the health of astronauts and make your own astronaut model out of household materials. Don’t forget to give it a familiar face!

Week 2: Discovering Our Solar System

Get ready for a tour of our Sun, Moon and planets. Study the different characteristics of each planet, discover the real distances between planets and learn how the Moon was formed. Plus, create a solar system model that you can learn from and admire.

Week 3: Investigating Comets and Asteroids

It’s time to take a close look at different types of rock-like objects, or minor bodies, that fall from the atmosphere to Earth. Watch an exciting demonstration in which we make a comet from dry ice, then join us in investigating and categorizing Earth rocks and meteorites.

Week 4: Understanding Rockets and Rovers

Travel back in time to uncover the different designs and processes that have been used for some of the most famous space missions. Put your new engineering knowledge to the test when you build your very own balloon rocket and prepare the launch of the year, all from the comfort of home.
