Simple Machines

Grades 2-6

Students identify simple machines in a robot’s house and compound machines in the tool shed.

This game has sound.

Step into a robot’s wacky house and start hunting for hidden simple machines! Each room has 10 to uncover—plus tons of laughs, quirky surprises, and Easter eggs along the way. Every time you find one, figure out what it does, name the type of machine, and watch clear, animated demos that show exactly how it makes work (or fun!) easier.

Once you’ve mastered the house, head outside to the Tool Shed, where you’ll take things up a notch. Here, you’ll discover how simple machines combine into powerful compound machines—and see how working together makes them even stronger.

Push, pull, spin, and roll your way through as you learn about:

Compound Machines
Gears
Inclined Planes
Levers
Pulleys
Screws
Wedges
Wheels & Axles

By the end, you’ll be a machine master, ready to invent amazing contraptions of your own!

Game Description

Glossary of Terms

Compound Machine
- Two or more simple machines working together to make work easier.
  Examples: Wheelbarrow, Can Opener, Bicycle
Gears
- Two toothed wheels fit together either directly or through a chain or belt so one wheel will turn the other. Some gears may have a screw or a toothed shaft in place of one of the wheels. A gear may also be a combination of toothed wheels that produces a certain speed (such as a bicycle’s topgear which makes the bike go fast, and the low gear for slow speed.)
  Examples: Clock, Automobile, Drill
Inclined plane
- A sloping surface, such as a ramp. An inclined plane can be used to alter the effort and distance involved in doing work, such as lifting loads. The trade-off is that an object must be moved a longer distance than if it was lifted straight up, but less force is needed.
  Examples: Staircase, Ramp, Bottom of a Bath Tub
Lever
- A straight rod or board that pivots on a point known as a fulcrum. The fulcrum can be moved depending on the weight of the object to be lifted or the force you wish to exert. Pushing down on one end of a lever results in the upward motion of the opposite end of the fulcrum.
  Examples: Door on Hinges, Seesaw, Hammer, Bottle Opener
Pulley
- A wheel that usually has a groove around the outside edge. This groove is for a rope or belt to move around the pulley. Pulling down on the rope can lift an object attached to the rope. Work is made easier because pulling down on the rope is made easier due to gravity.
  Examples: Flag Pole, Crane, Mini-Blinds
Screw
- An inclined plane wrapped around a shaft or cylinder. This inclined plane allows the screw to move itself or to move an object or material surrounding it when rotated.
  Examples: Bolt, Spiral Staircase
Simple Machine
- A machine with few or no moving parts. Simple machines make work easier.
  Examples: Screw, Wheel and Axle, Wedge, Pulley, Inclined Plane, Lever
Wedge
- Two inclined planes joined back to back. Wedges are used to split things.
  Examples: Axe, Zipper, Knife
Wheel and Axle
- A wheel and axle has a larger wheel (or wheels) connected by a smaller cylinder (axle) and is fastened to the wheel so that they turn together. When the axle is turned, the wheel moves a greater distance than the axle, but less force is needed to move it. The axle moves a shorter distance, but it takes greater force to move it.
  Examples: Door Knob, Wagon, Toy Car
