What Can We Lose? What Do We Lose as we Gain Force With A Lever?
Third graders view a demonstration of a teeter totter as a basis for assessing pre-knowledge of a lever. They create a KwL chart. Students work in small groups to conduct a variety of experiments. The first requires students to tie books...
Curated OER
Simple Machine Test
Students complete several worksheets about machines. In this machine lesson students complete several handouts that describe the different machines and how pulleys work.
Curated OER
Optical Illusion Machine
Students explore optical illusions. Using Legos, they construct and motorize a machine that has an axle that's geared up and geared down, complete a worksheet, and answer discussion questions.
Curated OER
Simple Machines, Odd Machine
Students construct a device to 'launch' a marshmallow at the teacher and then discuss various forms of levers. They work in teams to design catapults and identify different kinds of levers.
Curated OER
Simply Unique
Students identify, compare and contrast simple machines and their functions. They work together in groups to complete experiments using the simple machines. They write in their journals to reflect on the lesson.
Curated OER
Match the Machine
Students identify simple machines found in different environments. In this matching lesson, students match the machine with the place it belongs.
Curated OER
Snow Day
Eighth graders work in small groups to design and build a snow remover while looking at a snow design brief. They combine 2 or more simple machines to form a compound machine following the design brief in order to meet the required...
Curated OER
Incline Planes
Students determine the forces necessary to move a truck on an inclined plane with weight and slope as variables. They identify the cheapest way to transport trash to local garbage disposal sites.
Curated OER
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
The Physics of Tools
Students investigate the nature and work of simple tools and mechanics.
They explain how each simple machine can be used in real world applications. They explore levers, balance beams, windlasses, wedges, gears, ocarinas, harmonicas,...

Simple Machines: Inclined Plane
Young scholars use an inclined plane to move a heavy load.
Curated OER
Simple Machines - Levers
Fourth graders lift objects with the fulcrum and load in various positions and then experiment with how much force is exerted by the effort and load arms of the lever. They place 5 paper clips in the load and move the fulcrum to match...
Curated OER
Simple Machines or Are They?
Students discover basic machines and how they make completing work easier. They identify two basic machines, the inclined plane and the lever and the functions of these simple machines.
