This series is designed to introduce children to the technology around them in a way that is both informative and enjoyable. Step-by-step instructions and illustrations show children how to make their own simple models, and the text encourages them to investigate the scientific principles that make these models work. The books are relevant to the National Curriculum for Science and contain notes for parents and teachers. This book uses simple technology projects to encourage children to investigate wheels - how they work and how they can be used. From simple rollers for moving heavy objects, children go on to make more advanced trolleys using wheels and axles. Other work includes designing a passenger seat, experimenting with safety belts and making cogwheels and water wheels. The text aims to help children find out more about the forces involved in work on wheels and the energy needed for making their models move.
