Simple machines make the things we use in everyday life function. Engineers use - and combine - simple machines to design complex devices to make our lives easier!
Simple Machines Curriculum
The engaging resources from TeachEngineering featured here, by grade band, exemplify simple machines curriculum.
- An Introduction to Inclined Planes An Introduction to Inclined Planes
Students are introduced to the concept of simple tools and how they can make difficult or impossible tasks easier. They begin by investigating the properties of inclined planes and how implementing them can reduce the force necessary to lift objects off the ground.
- The Benefits of Inclined Planes: Heave Ho! The Benefits of Inclined Planes: Heave Ho!
Why does setting up an inclined plane on the back of a truck make it easier to load and unload? What's the difference between dragging an object up a slope versus lifting an object straight into the air? Have students learn about the engineering behind the practicalities of inclined planes.
- Solid Rock to Building Block Solid Rock to Building Block
Students continue their pyramid building journey, acting as engineers to determine the appropriate wedge tool to best extract rock from a quarry and cut into pyramid blocks. Using sample materials (wax, soap, clay, foam) representing rock types that might be found in a quarry, they test a variety of...
- Powerful Pulleys Powerful Pulleys
Students learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they ident...
- Pulley'ing Your Own Weight Pulley'ing Your Own Weight
Using common materials (spools, string, soap), students learn how a pulley can be used to easily change the direction of a force, making the moving of large objects easier. They see the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple/combined pulleys. ...
- Slide Right on by Using an Inclined Plane Slide Right on by Using an Inclined Plane
Students explore building a pyramid, learning about the simple machine called an inclined plane. They also learn about another simple machine, the screw, and how it is used as a lifting or fastening device.
- Engineering: Simple Machines Engineering: Simple Machines
Students are introduced to the six types of simple machines — the wedge, wheel and axle, lever, inclined plane, screw, and pulley — in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today.

- The Advantage of Machines The Advantage of Machines
In this lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. Already encountering simple machines everyday, students will learn about their widespread uses in improving everyday life.
- A Simple Solution for the Circus A Simple Solution for the Circus
In this activity, students are challenged to design a contraption using simple machines to move a circus elephant into a rail car.
- Just Plane Simple Just Plane Simple
This lesson introduces students to three of the six simple machines used by many engineers. These machines include the inclined plane, the wedge and the screw.
- Tools and Equipment, Part I Tools and Equipment, Part I
Students act as engineers creating a design for a ramp at a construction site by measuring four different inclined planes and calculating the ideal mechanical advantage versus the actual mechanical advantage of each.
- Machines and Tools, Part II Machines and Tools, Part II
In this activity, students gain first-hand experience with the mechanical advantage of pulleys. Students are given the challenge of helping save a whale by moving it from an aquarium back to its natural habitat into the ocean.

- Simple Machines and the Rube Goldberg Challenge Simple Machines and the Rube Goldberg Challenge
Students research and learn about simple machines and other mechanisms through learning about a Rube Goldberg machine. Student teams design and build their own Rube Goldberg devices that incorporate at least six simple machines. This project is open-ended with much potential for creativity and fun.
- Splash, Pop, Fizz: Rube Goldberg Machines Splash, Pop, Fizz: Rube Goldberg Machines
Refreshed with an understanding of the six simple machines; screw, wedge, pully, incline plane, wheel and axle, and lever, student groups receive materials and an allotted amount of time to act as mechanical engineers to design and create machines that can complete specified tasks.
