Yes! As #2 states in the challenge packet “2. The launching force must be supplied by elastic solids (springs, rubber bands, etc.) or by gravity. ”
Since a trebuchet is using gravity (in the form of a counterweight), they are allowed. A trebuchet is actually a specific type of catapult.

Yes, teams should strive to build catapults that are calibrated to go from 1 meter to 11 meters (or any meter mark in between!). This is what truly makes this year’s challenge difficult!
*The distance won’t be determined until the district meet, so it will be randomly determined at the very start of the meet. The ‘first’ distance will be between 1-6 meters, and if some teams get that first randomly determined distance, then the 2nd distance would be randomly determined 7-11 meters (only teams that get the first target ‘in’ would get a 2nd shot at a farther distance).
First Target: either 1, 2, 3, 4, 5, or 6 meters (randomly determined at district meet by meet organizers – same for all teams)
Second Target: either 7, 8, 9, 10, or 11 meters (randomly determined at district meet by meet organizers – same for all teams)
Comments Off on How will the distance be determined? The blog refers to being determined at the district meet. Do they need to be ready to adjust their catapult for anything from 1-11 meters?
