This book is a very hands on and helpful guide for doing science projects. It has 20 activities broken down within the book to learn different things on molecules and other science activities as well. It covers: building blocks, super chains, breakdown,spacey, clingers, on the move, uphill climbers, tug of war, escape, mixers, separate, crystals, honeycombs, color changes, I.D., stretchy, heavy water,cleansing power, supporters, and sinkers. The book offers several resourceful charts and illustrations along with some guides and/or suggestions in the front of the book. It basically has quick and easy lesson plans laid out for each activity. It introduces the activities then lists the materials needed, the procedure, what the result should be, and also explains why. These are quick, easy and fun activities for the you students to do. I would say the older end of the elementary spectrum though. ( )
