The Six Simple Machines

Wedges have one or two sloping sides that end in a sharp point and are used to lift, split, move, or stop an object.  Examples include knives, chisels, and nails.

Inclined Planes have a flat surface that connects a lower level with a higher level.  They include a roller coaster, skateboard ramp, and slides.

Screws are inclined planes wrapped around a shaft that turns in a circle to pull one thing toward another.  Besides actual screws, they include jar lids and light bulbs.

Levers are bars that rest on a support to lift or move things.  The one I always think of first is a seesaw, but scissors, wheelbarrows, and shovels are all levers, too.  There are three types of levers depending on where the fulcrum is placed along the bar.

Wheels and axles are two objects joined together at the center that rotate together.  Obviously, they include car and bike wheels, but they also include door knobs and screwdrivers.

Pulleys are grooved wheels with ropes used to lift and lower heavy objects easily.  Everyday examples include window blinds, flag poles, zip lines, and cranes.

Review What You Have Learned

A great way to pull all the knowledge together and assess what your children learned is by using an active recall activity.  But, worksheets and tests can be boring!  So check out these fun, colorful Simple Machine Sorting Mats!

All six different simple machine mats are shown with some of the accompanying cards.

There is one mat for each type of simple machine.  Children will then match the cards containing the definition, types, parts, and examples of that simple machine.  Then, they can check their work against the answer key.  They will have fun testing themselves to see what they remember!
