In this activity, students use their knowledge of levers to compete against another student in a simple game. Students will add wooden blocks or similar objects to a tray balanced on a pivot. By competing to keep the tray level, students will learn about the physics of levers.

This lab activity is designed to allow students to experience what an increase in mechanical advantage means. Students determine the mechanical advantage of three pulley set-ups. Students also measure the work input and output, then calculate the efficiency. Finally, students determine the relationship between the mechanical advantage and the efficiency of the pulleys.

This brief video lesson discusses the concepts of work and power and applies them to two common objects - a lightbulb and a grandfather clock. Discussion/assessment questions and suggested supplemental resources are also included.

In this lab activity, students will determine the effect of the angle of incline upon the force needed and upon the work done when pulling a cart up an incline to the same height at a constant speed. Students will record and graph data and write a comprehensive report summarizing the lab.

In this problem-solving activity, students design a device that will accurately and quickly deliver a specific load from one location to another by using non-traditional resources. Students will also understand the importance of power and energy in society.

In this lesson, students will investigate questions about how to calculate energy gain and loss and power during putts or other strokes.
