Simple Machine Experiments Using Seesaws, Wheels, Pulleys, and More: One Hour or Less Science Experiments (Last Minute Science Projects) - Softcover
Synopsis
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!

From School Library Journal
Gr 5-9-These books all begin with the same dilemma: a student has procrastinated. His or her science project is due tomorrow, but there's a solution: projects that can be done in an hour or less. Unfortunately, many, if not most, of the items on the "What You Need" lists for several of the experiments are specialized. For example, in Atoms it is suggested that oleic acid be borrowed from a science lab; in Electricity, a microammeter is needed; Energy requires an immersion heater; etc. No sources for these items are given. There's another big problem for quick experiments: Many of the formulas often require prior knowledge on the part of students. For example, the complicated equation to determine the kinetic energy of a basketball in Energy results in "joules or newton-meters"-neither of which is defined. Attractive volumes, but not very user-friendly.α(c) Copyright 2011. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
