Wheel and Axle
Fifth graders construct a wheel and axle model using a Lego Dacta set. They read and discuss informational text from the book "It's Science! Machines We Use," and in small groups create a simple machine using Legos.

Simple Machines V - Wheels and Axles and Gears
Fourth graders investigate the principles and uses of gears, and examine how gears can be used to alter the direction of motion or the speed of an object. They observe two cars with different sized wheels roll down an inclined plane,...

Simple Machines IV - Wheels and Axles
Fourth graders study everyday examples of simple machines. They examine how the combination of a wheel and axle works more efficiently than either in isolation. In a demonstration lesson plan, they see how a spring scale shows a force...

It's So Simple
Students use basic materials to create four simple machines. In this introduction to simple machines lesson, students are given four different scenarios that require a simple machine in order to solve. The students use devices such as a...
Curated OER
Simple Machines
Fourth graders discover the principles and uses of gears noting that they can be used to change the direction of motion or the speed of an object. They may also change the force and/or distance through which an object turns. They then...
