PROJECTS WITH AIR

Twenty-seven experiments; from the very simple demonstrations that air has weight and occupies space (which are explained less simply and certainly illustrated less attractively than in other easy project books) to the ubiquitous tests for air pollution (e.g., counting the number of particles trapped on index cards), with investigations of convection currents, air pressure and Bernoulli's principle in between. But neither his overly familiar experiments, his unbending vocabulary (withdraw, inverted and place for take out, upside down and put are typical) nor his method of starting right in on directions with no orienting background or motivating questions (you don't even know what you're looking for until you've gone through what could seem like a lot of meaningless motions) indicate that Simon has taken any trouble to improve on existing collections.
