Science Experiments With Simple Machines (Paperback)
|This book contains a variety of simple experiments that introduce middle grade readers to basic scientific principles related to simple machines. Students learn about first-, second-, and third-class levers, wheels and axles, pulleys, slopes or ramps, screws, winches, gears, belt-driven machines, concepts of fulcrum, effort, and load, and the many different ways simple machines can be used to make a task easier. Each double-page spread deals with one aspect of simple machines and features "In Action", "Keep Thinking", and "Don't Stop There" panels. These point students to connections to be made throughout the book, as well as loads of ideas about how to vary experiments, try out new ones, and keep on making scientific discoveries.|
