NOTES
What do flagpoles and some window blinds have in common? They use pulleys to perform work! Pulleys are simple machines. They help us to do jobs more easily. But don't take our word for it. Put pulleys to the test with the fun experiments you'll find in this book. As part of the Searchlight BooksTM collection, this series sheds light on a key science question―%x;How Do Simple Machines Work? Hands-on experiments, interesting photos, and useful diagrams will help you find the answer!
