This book has 5 chapters Biology, Chemistry, Physics, The Planet Earth, and The Human Body. Each experiment has background information on what you will be learning about.The first experiment for example is putting food coloring in water, and placing a white carnation in the water, to watch the flower change colors as it draws the colored water up through its roots. But the introduction explains live things are very complex, that there are a lot of things happening inside that we don't see.After each introduction it states a question to engage the participants. Then provides a material list, procedure steps, and one of my favorite parts is it also explains what's happening during the experiment. Each experiment also has a follow up question in which the answer is provided in the back of the book.But that is not all there is included in this book there are also words to know, jokes, even different websites pertaining to each experiment.This book is great for parents who want to teach kids about science or even just need something to do. Not only are there great experiments but also very detailed descriptions on what takes place during each experiment. Each experiment has a lesson to be learned, most involve everyday household items you probably already have and even questions involving what you noticed happening during the experience. I have done a couple with a group of kids with ages ranging from 5-10 each of them discussing before and after results and they were all ready to do another after we were done.Overall I recommend this book to families who seek out things to do with family time, or perhaps with kids that are having a tough time with science who knows you might have the next world’s renowned scientist.
