Children will love this interactive book about six simple machines: the wedge, wheel and axle, lever, inclined plane, screw and pulley. There is hands-on interaction that will excite young readers from the cover of the book where they can spin gears to make the Sloth character go up and down to the pop-ups and flaps that fill the pages throughout the book. It will be on that your children will grab to read over and over again.
Did I mention it is a STEM book written for ages 7 to 10 years old, too? David Macaulay did a great job putting the fun back into learning with this book.
