As this book proves, trashology is one cool branch of science! Sometimes it's all about the trash, like the workshop about analysing waste produced by your school's cafeteria, or understanding the decomposition rates of garbage bags. Sometimes it's about comparing and contrasting, like the workshop about the cost effectiveness of one-use and rechargeable batteries. Whatever workshop is chosen, this book of experiments is peppered with inspiring sidebars from trashologists, tips on how to have an award-winning presentation in time for the science fair, and plenty of humour.
