Catapults Overdue

Explore the concepts of elasticity, energy and force as you build and test a ‘quick build catapult.’ Identify the variables that impact the catapult’s performance. Then, build a larger Viking Catapult. Engineering is an iterative process; test your design and refine so that your catapult is able to consistently launch a projectile to hit a specified target. Compare and contrast the two catapults. Investigate elasticity further by building an Egg Bungee (additional materials required).
