It's no stretch to claim that catapults are fun. Launch your students into a hands-on application of concepts such as torsion and elasticity as they learn the physics behind overcoming gravity and hurling objects through the air - SAFELY. Your students will get the additional benefit of a historical perspective (catapults were once a basic tool of war) as they consider design improvements in the process of projectile launching. By relating the effects of different force settings to distance projections, you can also introduce your students to the analysis of frequency distributions.
