Zig Zag Bopper
Source Institutions
In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.

Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

Build a Lever
Source Institutions
Learners build a lever and use it to lift a load. With the load on one end of the ruler, learners add coins to the effort cup at the other end until the load is lifted.

Action Figure
Source Institutions
In this project, students explore how levers work, by making a puppet with moving limbs.

3 Classes of Levers
Source Institutions
In this physics activity (page 3 of the PDF), learners will move a load using a lever of each of the 3 classes. They will explore the differences between these classes and which are more effective.

Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

Balancing Act
Source Institutions
In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.
