Classroom Resource

Simple Machines StudyJam

Subject Area





Simple machines decrease the force, or effort, needed to lift and move heavy objects. There are several different types of simple machines, including levers, wheels and axles, pulleys, inclined planes, wedges, and screws.

The classroom resource provides a slide show that will explain the different types of simple machines and how they work. This resource can provide background information for students before they conduct their own investigations. There is also a short test that can be used to assess students' understanding.

    Science (2015) Grade(s): KG


    Use observations and data from investigations to determine if a design solution (e.g., designing a ramp to increase the speed of an object in order to move a stationary object) solves the problem of using force to change the speed or direction of an object.*

    Students know:
    • The relative speed or direction of the object before a push or pull is applied (e.g., faster, slower).
    • The relative speed or direction of the object after a push or pull is applied.
    • How the relative strength of a push or pull affects the speed or direction of an object (e.g., harder, softer).


    Students are able to:
    • Conduct an investigation.
    • Collect and record observations from tests of an object or tool to determine if it works as intended.
    • Organize information in a usable format.
    • Analyze data from tests to determine change in speed or direction.


    Students understand that:
    • Simple tests can be designed to gather evidence to support or refute ideas about the effects on the motion of the object caused by changes in the strength or direction of the pushes and pulls.
