If your child is struggling with science, then this book is for you; the short book covers the topic and also contains 5 science experiments to work with, and ten quiz questions.
This subject comes from the book "Sixth Grade Science (For Home School or Extra Practice)"; it more thoroughly covers more third grade topics to help your child get a better understanding of sixth grade math. If you purchased that book, or plan to purchase that book, do not purchase this, as the problems are the same.
