Grades 6–12. Launch projectiles and learn about levers. Build a paint stirrer catapult and conduct trials to explore how the fulcrum size and position, plank length, effort force, and load affect trajectory and distance. Student groups use this data to modify, retest, and troubleshoot the prototype. For assessment, each group’s best design competes in a class catapult challenge for height, distance, and accuracy.
Grades 6–12. Launch projectiles and learn about levers with a desktop catapult built from paint stir sticks. Modify the catapult and conduct trials to explore how the fulcrum size and position, plank length, effort force, and load mass all affect trajectory and distance. Student groups use this data to update, retest, and troubleshoot the prototype to perfect the catapult. For assessment, each group’s best design competes in a class catapult challenge for height, distance, and accuracy. Students are sure to better understand the principles behind levers after this enjoyable activity. Supports 15 design teams of 2 to 3 students. Includes instructions and diagrams.
