The Spinning Blackboard and Other Dynamic Experiments on Force and Motion
Grade 6 Up?Twenty-three demonstrations and experiments illustrating Newtonian laws of force and motion, based on exhibits at a hands-on science museum in San Francisco. The projects are easy to assemble. Some materials may be ordered from the Exploratorium, but directions for using substitutes are given. Each experiment, called a snack, includes a list of materials, instructions, things to do and notice, and an explanation of "What's Going On?" In some cases there are directions for assembling apparatus of two different sizes, appropriately called large and small snacks. All the projects are fun and can be used for recreation as well as in the classroom. Pen-and-ink drawings and black-and-white photographs are especially helpful in clarifying the procedures. An innovative and creative collection.?Margaret M. Hagel, Norfolk Public Library System, VACopyright 1996 Reed Business Information, Inc.
