Several weeks ago in physics, we learned about projectile motion. As a way to relate what we are learning to the "real world", students had to build catapults and measure the distance and velocity of their projectile - a marshmallow.
After students created their catapults and measured velocity, launch angle, and distance, I asked them to make modifications to their catapults to increase horizontal distance. We then had a catapult competition to see which group's catapult would launch the marshmallow the farthest.
The catapult winners from each class:
