This fascinating book is different from other science book.It has many, many different experiments and projects to try out. From building a escalator to making a simple computer...That really works!! Each experiment is clearly photographed step by step , it is so ever easy to follow them! This book is a must. If you enjoyed this book, why not try the others? You won't regret.

My kids always want to know why or how something happens. This is a great book for them to look at (marvelous pictures) and for us to select projects from that explain some of the stuff mom and dad don't know. My seven and ten year old can read and understand the vocabulary without getting lost in any scientific jargon. A great help for classroom project, science fair entries, long summer days or rainy weekends.
