How do you keep a door from closing? Try using a wedge! Wedges are one of the six simple machines that help make work easier by using mechanical advantage. In Wedges Make a Point: Simple Machines for Kids, readers ages 5 to 8 learn how a wedge's shape makes it perfect at stopping something heavy from moving, and separating material to split something--like banana bread--apart. Glossary, photos, and a hands-on activity make this book fundamental for STEM learning."--
