In this concept introduction task, students will explore a thinking device (a powerful question) to consider the impact that levers have on work.

Lesson Materials

AISI_Logo.jpgHow can we change the effort force needed to lift a load?

Lab Problem: How can you design a prototype lever to reduce effort force?

In this collaborative lab activity, students will design prototype levers, measure the effort force required to lift a load, and revise their prototypes to reduce the effort force needed to complete the task.
