Learn how simple machines make work easier in these colorful nonfiction picture books all about science and engineering!
Have you ever played on a seesaw? You were using a lever!
A lever is one of six simple machines that are designed to make different kinds of work easier. Lifting, pulling, pushing―all these tasks are more efficient when you use a simple machine. 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. Need to lift a heavy rock? Use a lever! Need to push a log out of the way? Use a lever! Know where else you can find levers? In your own body―when you lift an object and carry it in your hand, you are using your arm as a lever.
Concepts including forces, mechanical advantage, and different classes of levers come clear with engaging illustrations and lots of real-life examples that kids can spot in their home, schools, and neighborhoods.
An introductory poem offers language arts connections while a hands-on activity at the end reinforces concepts in the book. A glossary and photographs offer even more supplemental learning opportunities.
Levers Lessen the Load is part of a six-book set of Picture Book Science books designed to introduce young engineers to physical science concepts. Other titles are Wedges Make a Point, Screws Keep Things Secure, Pulleys Pull Their Weight, Wheels Make the World Go Round, and Inclined Planes Ramp It Up.
All books are leveled for Guided Reading level and Lexile and align with Common Core state standards and Next Generation Science Standards.
All titles are available in paperback, hardcover, and ebook formats.

K-Gr 3--Humorous illustrations featuring diverse characters introduce children to simple machines and their uses through familiar examples. Screws may be used to assemble a tree house, or ramps may help someone in a wheelchair access the library. Funny situations like using a pulley to lift an elephant off a book are also provided. Glossary terms are bold within the text, while other key words may appear in a different color or font size for emphasis. Diagrams show how force is redirected or focused by each simple machine. Photos of simple machines in action are included within the glossary. Directions in the back of each book help readers with hands-on activities such as constructing a water wheel or designing a marble run. Free classroom guides are available through the publisher's website. VERDICT The combination of humor and everyday experiences make this an enjoyable introduction to simple machines for primary grades.
