Each book in this series provides all the necessary ingredients to start children designing and making their own exciting technology projects, based on simple "recipes" that use readily available, low-cost materials. The projects give hands-on experience of technology in everyday life and are constructed in a way that makes finding out about technology fun. "Moulding Materials" introduces the reader to plaster, air-drying clay, papier mache and other materials that can be shaped, moulded, extruded and cast. Projects include making biscuits and bread, pots, puppets and jewellery.
