The spinning blackboard and other dynamic experiments on force and motion - Paul Doherty

The principles of physics apply to everyone's life, every day. The 23 fun, unique experiments in this book demonstrate some of these physical principles in ways you'll never forget. You can make a giant gyroscope out of a bike tire, or create your own artwork using a pendulum or a spinning disk. Other experiments examine bubbles, balance, tornadoes, momentum, and much more. * Find out why rocking a car will get it out of a ditch, and why earthquakes will knock down some buildings and leave others standing * Watch a penny and a feather dropped in a vacuum. Which one will hit the ground first? PAUL DOHERTY (San Francisco, California) is the director of the EXPLORATORIUM TEACHER INSTITUTE, an organization within the Exploratorium that uses the museum's interactive exhibits to introduce an inquiry based approach to middle and secondary school science education. DON RATHJEN (San Francisco, California) is a physics and resource teacher in residence at the Exploratorium Teacher Institute.
