A children's instructional book on how to use readily available materials to turn the house into a science lab Science teacher Bobby Mercer provides readers with more than 50 great hands-on experiments that can be performed for just pennies, or less. Each project has a materials list, detailed step-by-step instructions with illustrations, and a brief explanation of the scientific principle being demonstrated. From turning three pennies and two galvanized washers into a simple battery to crushing a soda can using atmospheric pressure, the experiments in this book call for materials that are recycled or repurposed--crayons, plastic drink bottles, balloons, ice cubes, and other basic items found around the house. Junk Drawer Chemistry also includes sidebars of fascinating chemistry facts. Educators and parents will find this title a handy resource to teach children about chemistry topics that include atoms, compounds, solutions, mixtures, reactions, thermodynamics, acids and bases, and more, while having fun at the same time.
