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 prong position
  • Counterweight
  • Projectile

Before your students explore these characteristics, be sure to establish a time limit that fits your classroom scheduling needs. The activity requires 2 to 3 class periods.

Extend this lesson by:

  • Comparing and contrasting mechanisms that power trebuchets, catapults, and sling-shots
  • Incorporating technology such as video analysis or probeware to measure the velocity of the projectile
  • Calculating the gravitational potential energy provided by the counterweight at the release point

This highly engaging project connects science, engineering, and history. Materials support 15 pairs. Eye protection, counterweights (washers or coins), and a balance are needed but not supplied. Includes instructions.

  • This item is only available from Carolina Biological Supply Company.
