This book is directed at the self teaching, homeschool kid. These, are not of course, exclusive requirements, but that is who the intended audience is. To do science in a home school style, the experiments are laid back and I speak directly to the brilliant and curious children who are looking forward to a little hands on exploration. It contains 10 of my children's favorite experiments. There are several steps that require supervision and I hope that the families that start them, enjoy them together as much as my family did.
