WHAT MAKES THE WHEELS GO ROUND: A First Time Physics

This belongs in the same category as A Child's History of the World -- to the same age group (about 9 to 12), but in the hands of a skillful teacher, it appeals could be used for younger --and for older -- children, as an ideal introduction to physics. In terms, illustrated by facts familiar to every child, the author has presented the basic discoveries in the field of physics. He discusses the elements; solids, liquids and gases; heat and cold; weight of air; magnetism; protons and electrons; generators and motors; locomotives, steam, engines; gravity and tension; evaporation; inertia and friction; sound, light, wave lengths; telephones, radio -- and the scientific spirit in the approach to everything. Amazingly comprehensive and crystal clear.
