Inspire creative engineering in your classroom with this high-flying design challenge! In the introductory activity, students build a basic catapult using simple materials. Then they test their machines to determine how variables, such as the length of the lever arm and mass of the projectile, affect launch distance. Using their data and observations, students brainstorm how to improve the design to accurately launch a projectile at a target. Students apply their knowledge of levers, potential and kinetic energy and projectile motion in this fun competition!
