Levers in the Body: They Are Not What You Might Think!
Young scholars investigate lever systems in the human body and compare arm anatomy to model. In this human levers lesson students graph and analyze their results.
Curated OER
Levers
In this levers worksheet, learners compare the three classes of levers. Students determine how the location of the fulcrum effects the amount of force needed. Then learners complete 20 fill in the blank questions and 6 word problems.
PBS
Helping Hand
Reach out and grab something. Given the task of picking up objects at least two feet away, pupils design and build a grabber. The last activity in a series of five challenges requires learners to use information about fulcrums and levers.
Curated OER
Fulcrums in Our Body
Second graders discuss fulcrums and levers and identify at least two fulcrums and levers on their bodies. They also identify fulcrums and levers on animal bodies.

You are Uniquely You
Students compare and contrast simple machines and their functions. In this cross-curriculum science simple machines lesson, students observe examples and read about simple machines, then use body movement to demonstrate how machines...
Curated OER
Torque Me Off
Students investigate the lever and the mathematics associated with levers. They determine the conditions necessary to balance a system of forces around a fulcrum.
Curated OER
Levers
In this levers learning exercise, students review how to calculate mechanical advantages using forces and using distance. Students explore the three types of levers. Then students complete 20 fill in the blank questions and 6 problems to...
