Trebuchets Kit for 15 student pairs

Trebuchets Kit: Grades 6-12. Design teams build functional desktop sized trebuchets to launch corks for accuracy or distance.As students convert potential energy to kinetic energy, they learn about first class levers and explore characteristics that affect trebuchet performance. To save time no special tools are required  and all design teams build the same starter trebuchet. Six main modifications can be made to the design to alter its performance. Frame structure, Throwing arm length, Sling length, Firing pron position, Counterweight and Projectile. This activity requires 2 to 3 class periods. 15 teams
