If you were designing a wheelbarrow, how would you make it move easily when you pushed it? How about wheels? In Wheels Make the World Go Round: Simple Machines for Kids, readers ages 5 to 8 learn how wheels work along with axles and how they use mechanical advantage to make it easier to move heavy objects from one place to another. Glossary, photos, and a hands-on activity make this book fundamental for STEAM learning.
