Introduces wedges, including how they function and how they are used in everyday objects to make life easier.

Readers learn how this simple machine makes it easier to move things from one place to another. They also learn a wheel works with an axle. By the end of the book, readers know the difference between complex and simple machines and how wheels are used in everyday life to make work easier. How can we lift and lower things? How can we move heavy loads from one place to another? By using simple machines! Wheels, wedges, levers, pulleys, screws, and inclined...

Readers learn how this simple machine makes it easier to split things apart or stop them from moving. They learn how thicker wedges need more force to split something apart than thinner wedges. By the end of the book, readers know the difference between complex and simple machines and how wedges are used in everyday life to make work easier. How can we lift and lower things? How can we move heavy loads from one place to another? By using simple machines!...

Readers learn how this simple machine makes it easier to move things to different levels. They learn how flatter slopes use less effort than steeper slopes. By the end of the book, readers know the difference between complex and simple machines and how inclined planes are used in everyday life to make lifting and lowering objects easier. How can we lift and lower things? How can we move heavy loads from one place to another? By using simple machines!...
