Simple Machine Experiments Using Seesaws, Wheels, Pulleys, and More: One Hour or Less Science Experiments (Last-minute Science Projects) Robert Gardner

Have you waited until the last minute to start your science project? Don't worry, award-winning author Robert Gardner has you covered! Each experiment in SIMPLE MACHING EXPERIMENTS USING SEESAWS, WHEELS, PULLEYS, AND MORE follows the scientific method, and can be completed in an hour or less. Explore using levers to control motion and lift, and how the steepness of inclined planes affects the force needed to move something. Most experiments also include ideas for science fair projects, in case you have more time than you originally thought!
