New Party Themes at the Ontario Science Centre

Looking for an amazing birthday party full of concocting, examining, and experimenting? Kids can explore principles of science at an Ontario Science Centre party. Choose a party theme, then relax and leave the entertaining and activities to the Party Pros. Parties run up to two hours for up to 20 children in a private party room. The fun is not over when the party is; you and your guests are invited to spend the rest of the day at the Ontario Science Centre!

The Ontario Science Centre is now offering parties for the younger crowd, starting at age 4. And, many new themes are available!

NEW! Parties for 4 to 7 Year Olds

Experiment, play, and create with Imagination Playground blocks to design and build the playscape of your dreams. Party staff will challenge you and your friends to work together to create a masterpiece, whether it’s a garden, a moon base, or an amusement park. It’s all up to you!

Parties for 5 to 9 Year Olds

Experience chemistry and explore the physical and chemical changes of matter with cool chemistry demos. Mix your own concoctions of "slime" (a polymer) and "ooblick" (a non-Newtonian fluid).

Experiment with optics and chemistry as you unlock the secrets behind popular magic tricks. Defy the laws of gravity and make an orb levitate. Create a balancing stick to amaze your friends and family!

Investigate Newton’s Third Law of Motion to determine how rockets launch into space and enjoy two interactive "launch" demos – a film canister rocket and a balloon rocket. Build and test a planetary lander with the goal of successfully landing it without damaging its cargo – an egg!

Parties for 10 to 12 Year Olds

Get geared up for fun! Use engineering principles, recycled materials, and your imagination to find the solution to a real life problem with your friends in the "lab," then build and test your very own personalized robot to take home.

Parties are available Saturdays and Sundays. For more details and rates, visit
