{"product_id":"earth-water-fire-and-air-book-walter-kraul-9780863157684","title":"Earth, Water, Fire and Air","description":"This book encourages children's interest in the natural world, showing a broad range of activities, games and toys to make that involve one of the four elements: earth, water, fire or air. The projects also introduce children to basic scientific principles -- such as gravity, momentum and light refraction -- in fun and creative ways.  Full instructions and diagrams are provided for making projects such as a waterwheel, paddle-steamer, propeller plane, parachute, windmill, simple pendulum clock, spinning tops, hot-air balloon and much more. Some are simple enough for a six-year-old, others are challenging enough for a twelve-year-old to enjoy. This new edition includes updated colour photographs and diagrams as well as a handful of new activities for all children to enjoy.","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49522451939601,"sku":"GOR007110392","price":6.3,"currency_code":"GBP","in_stock":true},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":49644802441489,"sku":"GOR009386088","price":3.49,"currency_code":"GBP","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":50480508600593,"sku":"CIN0863157688G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51695005368593,"sku":"CIN0863157688VG","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0863157688.jpg?v=1751265191","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/earth-water-fire-and-air-book-walter-kraul-9780863157684","provider":"World of Books ","version":"1.0","type":"link"}
