Curated OER
Simple Machines: Pulleys
Students observe and analyze how pulleys work and how a double pulley can make work easier. In small groups they use a fixed pulley system and a double pulley system and draw a picture of how their pulley system functions. Students...

Is a Pulley a Special Kind of Lever?
Fifth graders use information from their text to read and discuss pulleys and levers. They examine a top sketch of the arrangement of a fixed pulley. Working in groups, 5th graders perform experiments to test the effect of using a pulley...
Curated OER
Simple Machines
Students explore the concepts of force and effort by observing simple machines. In this physics lesson, students attempt to sharpen a pencil without any help, bite into an orange with their lips curled over their teeth, and other...

Simple Machines III - Pulleys
Fourth graders are introduced to a spring scale to show that the forces on both sides of the pulley are the same. They break into groups to lift objects with fixed pulleys and with multiple looped pulleys and then measure the force...

TE Activity: Pulley'ing Your Own Weight
Students experiment with common objects such as spools, string and soap to determine how pulleys make it easier to move large objects. They look at the difference between fixed and movable pulleys. They examine the many uses engineers...
Curated OER
Simple Machines
Students engage in a lesson that explores the concept of simple machines. They view a powerpoint media presentation and then are introduced to adult volunteers for the lesson. Each volunteer is at a station with a simple machine and...
