The book Simple and Complex Machines explains that machines help people do work. Machines can help make work easier, faster, and safer. The amount of work required depends on the amount of force needed and the distance to be traveled. Seven types of simple machines are described: inclined plane, wedge, screw, lever, wheel and axle, gear, and pulley. Each machine can be found in many common devices. Complex machines combine several simple machines into one new machine in order to perform specific jobs.

I.Files allow each student in a group to read about a specific, high-interest topic related to unit concepts. Groups then discuss several files to identify common details in order to answer a Key Question. In this I.File, students learn about sailboats and how they work as complex machines. This I.File is written at the middle of three reading levels.

The book Doing Work defines work as using force to move something. Pulling a wagon, lifting a box, and turning a page in a book are all work. Using a force that does not lead to motion is not considered to be work. It takes more work to move something heavy than to move something light. It also takes more work to move something far than to move something over a short distance. Machines help us do work more easily or more quickly. Simple machines have just one or a few parts. Simple machines can be combined to form complex machines that have many parts. Each machine helps perform certain tasks.

Lesson Plan

The Unit Resource List identifies all the current resources within the Machines unit. Use this list to plan which resources to use, to note printing or projecting, and to record other notes about each resource.

The NGSS Correlations Chart lists the key student resources within the unit, then identifies which of the Next Generation Science Standards each resource supports. The chart correlates to relevant Performance Expectations using NGSS codes, which are explained at the end of the document. Using a variety of resources will help develop student proficiency in the skills required for each Performance Expectation.
