圖書介紹

Pull on your gloves and experience the science of trashology! It's all about the stuff that's thrown away: analyzing the waste produced by your school's cafeteria, understanding the decomposition rates of garbage bags, comparing the cost effectiveness of one-use batteries versus rechargeables. This book is peppered with enlightening extras and humorous asides, such as background stories from expert trashologists. Plus, kids get tips on how to rock the science fair.
