Why it matters. Levers, pulleys, wheels and ramps are how people have made hard jobs easier for thousands of years. Spotting them in daily life is a nice discovery for a fourth grader.
Where children slip. Children often name the object instead of the machine, saying "a seesaw" when the answer is a lever. Ask "what does it do to the force?"
Try it away from the page. Go on a machine hunt around the house and yard. A door handle, a flagpole and a slide are all in the worksheet, and you will find more.
