Book excerpt: Aiming to bring the fun back into teaching and learning science with things that slide, pivot, turn, rub and work, this book offers help to teachers in presenting scientific principles and simple mechanics through hands-on, co-operative learning activities. Using inexpensive materials (for example, tape and paper clips), students at grades 3-8 should be able to learn to build simple machines, such as levers, pulleys, spring scale, gears, wheels and axles, windmills and wedges. Experimentation with these gadgets demonstrates how things work.
