I am a home schooler of an 8th grade student. Both my child and I have enjoyed the time and knowledge we have put into this book. The pictures and explanations are very enjoyable. We find that we can easily use the information for experiments or further studies. I am going to use this particular book for my now 4th grader when he reaches the 8th grade level. Thanks to the authors and researchers for their hard work to make my life a little easier.
