Lets Exp Sci Make It Go CL

This book presents questions and clear photographs (in the true DK fashion) on elementary science questions for children. It introduces children to the basic principles of physical science and includes projects parents and children can make with everyday materials and equipment by following full-color child-friendly photographic instructions. Topics include motion (kinetic and potential energy), magnetism, resistance and friction, as well as simple machines, such as levers and fulcrums, pulleys, and rollers. Science should be intesting and fun; this book makes it so.
