This book gives a wide variety of information on sharks with lots of pictures, diagrams, and captions. Most of the pages of the book are not taken up with paragraphs but pictures with arrows and captions and graphs and pictures which can hold kids attention more. I do not think that this book is good for anything older than 3rd grade but can be used in an ocean unit and may be used for a research paper as a print source for information. I could see my 3rd graders doing a science section on the ocean and doing a small research project on one ocean creature and maybe a poster gallery walk and if someone chose sharks then they could use this as a resource. I also like that it has a glossary in the back and a small quiz on the last page that is cool but I would probably not use. ( )
