The Big Idea:
Simple machines help us do work

What Students Need to Learn:
Simple Machines:
                  *Lever
                  *Pulley
*Wheel & Axle—(gears: wheels with teeth and notches; how gears work, and familiar use—for example—in bicycles)
*Inclined plane
*Wedge
*Screw
Friction, and ways to reduce (lubricants, rollers, etc.)

*Multiple Choice
There will be a multiple choice section consisting of 15-20 questions.  This is based largely on our classroom discussion.  Please encourage your child to be paying attention during our science listening and learning time.

*Vocabulary Section
Be familiar with the following terms:
Force, friction, inclined plane, lever, pulley, screw, wedge, wheel & axle, and work

*Please use the practice test to review with your child
