We read the picture book, Down Down Down, by Steve Jenkins. It is about what lives at each level of the ocean. I love his books! After reading the book and completing several activities, the students worked in small groups to create an Ocean Layer Tower using bulletin board paper and construction paper. These turned out great! Here is a link to a FREE animal chart activity to do with the book! Here is a link for an inexpensive packet that contains comprehension questions and project sheets!
