{"product_id":"levers-wheels-and-pulleys-book-john-farndon-br-9780761413417","title":"Levers, Wheels, and Pulleys","description":"Early in the 17th century, Francis Bacon decided that the best way to learn about the world was to discover things for oneself. Since then, science has been a marriage of observation and experimentation. The experiments contained in each chapter allow young scientists to investigate basic principles using common household materials and easy-to-follow instructions. The titles are filled with dozens of color photographs that illustrate experiments and provide a glimpse of everyday and extraordinary uses of the subject. In addition, engaging features such as Did You Know? boxes provide fascinating facts. The In Focus sections offer in-depth looks at specific features of each subject. In The Real World boxes highlight pivotal experiments by real scientists.","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":53256389394705,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true},{"title":"US \/ GOOD \/ SBYB","offer_id":53256389624081,"sku":"CIN0761413413G","price":7.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780761413417.jpg?v=1773679835","url":"https:\/\/www.worldofbooks.com\/products\/levers-wheels-and-pulleys-book-john-farndon-br-9780761413417","provider":"World of Books ","version":"1.0","type":"link"}
