Summary: A fun way to learn for younger children!
Review: My 3 1/2 year old son loves this book! He can now tell me that blood is made of white & red blood cells, water, & platelets. This book puts the concepts down in a way that is easy for young children to understand. It also makes a fun book to read. I even learned a few things myself!
