Inclined Planes (Simple Machine Science)

If you need to move something heavy from one height to another, you need an inclined plane. These simple machines help us go up, and they help us go down. Moving vans use them, and so do people in wheelchairs. Inclined planes can also help us keep a door open and let us do skateboarding tricks at the skate park. Accessible text and vivid photographs help readers understand this essential science topic. A helpful graphic organizer and a useful glossary allow readers to easily navigate this book, making it a reading experience that is both educational and engaging.
