Grades 612. Go medieval in your science classroom as students convert potential energy to kinetic energy! Design teams build functional desktop-sized trebuchets to launch corks for accuracy or distance. No special tools, glue, or castles are needed. Students learn about first-class levers and explore characteristics that affect trebuchet performance. This highly engaging project connects science, engineering, and history. Materials support 15 student pairs. Includes instructions.
Grades 612. 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:
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.
