Have you ever played on a seesaw? You were using a lever! In Levers Lessen the Load: Simple Machines for Kids, readers ages 5 to 8 learn how levers and fulcrums can help us move far more weight than we can on our own. Explore concepts such as forces and mechanical advantage and be surprised at where you can find levers! Glossary, photos, and a hands-on activity make this book fundamental for STEAM learning.
