Gr 4-6-In this series, a variety of children in the illustrations carry out investigations, such as sifting a mixture of materials through a colander or comparing the elasticity of different garments. The experiments are age appropriate and use readily available materials. Step-by-step directions for each activity include a list of materials needed and whether the help of an adult is required. At the end of each experiment a "Because" statement explains the phenomenon just explored. Questions such as "Can you see magnetism work?" offer concepts to ponder in "Think about it" text boxes. There are also warnings for added safety-for example, "Batteries are safe to touch, but DO NOT try to look inside one." Back matter includes a list of additional books and websites to explore and suggestions of places to visit. VERDICT Handy for classroom demonstrations or individual exploration at home.
