Wow! I liked this book. It was the first time I had seen someone try to teach the periodic table to elementary kids using flaps. This is a stocky book with cardboard flaps covering many entries in the book. Children turn the flaps to reveal what is underneath. The kinesthetics appeal to me a lot as I know there are many students who need this physical touch to learn by. More importantly the science content provide by the authors is quite unique and inclusive. I have not seen so much information in so few pages and all done with such perfection. Students will learn science from the beginning of time all through to the future. They will learn about atomic models, astrophysics, biology, and chemistry in an enjoyable and well illustrated book. I love this book.
