This book of experiments is very intriguing. Ther are so many mini lessons, and experiments that could be done in the classroom to go along with lesoons, and they would not take that long to do either. I love the way that the book is organized. Ther are specific tabs for biology, chemistry, astronomy, geology/geograpgy, physics and weather; these tabs make it very simple to navigate throughout the book. The lesson and experiments in the book are very exciting and simple to do, like "your weight on the moon," experiment. In this experiment you only need a scale and a calculator, then each child weighs and divides his.her weight by six and that is his.her weight on the moon. It is very simple, but I bet the kids would have a lot of fun talking about that with their parents at the end of the day.
