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.

Learn how simple machines make work easier in these colorful nonfiction picture books all about science and engineering!

How do you keep a truck from rolling? A door from closing? And how do you cut through banana bread?

All of these questions have the same answer—a wedge! Wedges are one of the 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.

Scientific concepts including forces and mechanical advantage come clear with engaging illustrations and lots of real-life examples that kids can spot in their home, schools, and neighborhoods.
