This Pulleys Worksheet helps 4th graders label a pulley, compare fixed, moving, and compound pulleys, and explain how pulleys lift heavy loads. Includes an answer key — a no-prep way to practice simple machines science.
This Simple Machines Match Worksheet gives 4th Grade students six machines to pair with the jobs they do, plus everyday examples to name. An answer key is included, so checking work takes seconds.
This Levers Worksheet helps 4th grade students label the fulcrum, load, and effort, then name the class of six everyday tools. An answer key is included, so practice checks fast.
Simple and compound machines flash cards for 2nd to 4th grade: 16 fold-over picture cards, a practice page and an answer key included, so students learn to spot the simple machines inside everyday tools.
Work smarter, not harder!
Fourth graders learn that simple machines make work easier by changing the size or direction of a force. The six simple machines are the lever, pulley, wheel and axle, inclined plane, wedge and screw. A seesaw is a lever, a flagpole uses a pulley, and a ramp is an inclined plane. Kids learn that a machine does not create energy; it trades a longer push for a smaller force. The click comes when kids try to lift something heavy with and without a lever and feel the difference.
Simple machines are perfect for hands-on science. These moves let kids feel the physics.
Give groups a ruler, a pencil for the fulcrum and a few books. They move the fulcrum and find where lifting the books is easiest. Then they explain what changed.
Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).

Why it works: a big review of study methods ranked quick self-quizzing among the most powerful ways to remember (Dunlosky and colleagues, 2013).

The six simple machines are the lever, pulley, wheel and axle, inclined plane, wedge and screw. Each one makes work easier.
They change the size or direction of a force. You might push farther, but you need less force to move a heavy load.
A doorknob is a wheel and axle, a knife is a wedge, a jar lid is a screw, and a seesaw is a lever.
Find real examples around the house and try them out. Have your child lift something with and without a lever to feel the difference.
