Simple Machines Laboratory Kit for physical science and physics allows experimentation with four types of simple machines—the inclined plane, pulley, gears and levers.
This lab kit allows students to experiment with four types of simple machines—the inclined plane, pulley, gears and levers—and study their advantages. Students learn about gear ratios, first-, second- and third-class levers and pulley combinations, comparing their mechanical advantages to determine which setup provides the most benefits. Lab stations are easy to set up—student groups rotate through each, experimenting with one simple machine at a time. All of the activities can be completed in two class periods. Includes complete instructions with background information, student worksheets, sample data and answers to all questions.
Standard laboratory equipment, such as support stands, clamps, 250-g spring scales and meter sticks, are required but not included.
