Each foldout page examines a specific topic. Every one of these can be used to launch a scientific lesson. The topics include basics such as electricity, magnetism, Newton's Three Laws, simple machines, bicycles, trains, the workings of the internal combustion engine, etc. A timeline of technological developments, going back to early human civilization, is included.
This book also includes more esoteric topics such as the workings of fireworks, ears and sound, wavelengths of light, power plants, flotation of boats and ships, manned space flight, workings of lenses and light bulbs, the Internet, bar codes, and possible future developments such as the hydrogen-driven bus.
