|Celebrate your child’s birthday with amazing hands-on science activities full of concocting, examining, and experimenting! Choose the theme of the birthday party, then relax; leave the entertaining and activities to our "Party Pro." They will deliver a two-hour party for up to 20 children in your 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!|
NEW! Parties for 4-7 year olds
Experiment, play and create with Imagination Playground blocks to design and build the playscape of your dreams. Our 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 5-9 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!|

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.
