Students investigate levers. For this simple machine lesson, students study levers and  the mechanical advantage of using levers. They will collect data and illustrate their systems for eight different tests.

In this forces and machines activity, students will review vocabulary associated with forces including friction, inertia, and work. Students will also explain how simple machines help to do work easier. This activity has 10 matching, 6...

Students practice the 4 question strategy to form more questions and develop further experiments. The four questions are engage, explore, explain, and elaborate. They use the 4 question strategy on an investigation involving the mass...

Ninth graders determine when work is being done on an object. They define work and calculate work for several examples. They define and give examples of force and distance and define power and calculate power. They determine the...

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...
