This OFF Limits STEM Challenge is now closed. Check back soon to find out who the winners are.
Your challenge: to make a marble rollercoaster with the biggest loop!
The specs: you can be creative and use any materials you like to design and build your marble roller coaster. The only exceptions are pre-designed marble roller coaster kits, which cannot be used. Like our roller coaster engineer, Joelle Javier, please keep safety in mind! Parent/guardian supervision is recommended.
Submit your work: Complete a two-part form and submit a short video showing your marble roller coaster in action (maximum 1 minute). The video must include a measurement of the height of the loop, from top to bottom, and a demonstration of a marble going through the loop, in the same take. Note: The form will ask you a roller coaster question. You can find the answer to this question in the OFF Limits: Riding Roller Coasters video.
Judging: Mechanical engineer, Joelle Javier, from the OFF Limits: Riding Roller Coasters video, will be judging the videos! She will be looking for the entry with the largest functioning marble roller coaster loop. If more than one entry has a loop of the same size, she will be looking for other design features, like hills, banks, and more, to break the tie.
Deadline: Entries must be submitted by 11:59 PT on August 6, 2022.
Eligibility: this STEM challenge is for girls, nonbinary, and gender nonconforming youth aged 7-17 (as of August 6, 2022), residing in Canada.
Winners: Joelle Javier will select two winners: one aged 7-11 and another aged 12-17.
Prizes: Winners will each receive a prize pack valued at $55, generously donated by Canada’s Wonderland! Winners will also be featured on the CAGIS website, social media, and other communication channels.
