Make Work Easier!
Pupils work in pairs to design a lever. They conduct experiments using a penny and nickel to explore the uses of a lever.
Curated OER
Work Made Easy
Second graders maneuver placement of the fulcrum on the lever to see how to lift weight most easily. They role-play as archaeologists with the task of lifting a heavy rock from the dig site. They write in science journals about what...
Curated OER
Balanced Students
Students investigate the relationships between weights, and construct a balanced first class lever. They formulate a general equation for the relationship explored in the experiment and perform calculations.

Levers - An Interactive Lesson
Seventh graders identify the different parts of a lever. In this physics lesson, 7th graders draw a lever and label the different parts. They use the interactive board to create their own lever.
Curated OER
Changes in Force, Motion, and Energy
Eighth graders construct various machines and compare the work done by them.
