Projectiles, Physics and Punkin' Chunkin'

Innovation in Teaching Competition: Jerry Knox from Academy of Richmond County

Grade Level

Content Area/Instructional Strategy


In this project-based unit, medieval times provide a platform for students to learn about projectile motion and practice advanced algebra skills. Students learn about motion, velocity, acceleration, and parabolic equations to design and build catapults. Students then compete in a “Punkin’ Chunkin’” competition and see the results of their catapult designs. The unit concludes with students collecting and analyzing data from the catapult launches and reflecting on the unit.
