This booklet was created to provide students with a basic understanding of how the sea floor was created. Students are each assigned a specific category within the booklet and then spend time researching the topic so that they can label and explain the diagram as well as answer the questions. Students are then put into groups with others that researched the same topic to compare answers and develop a deeper understanding of the topic. Once the expert groups have completed their share out, students are organized into small groups that contain one expert from each topic. Students then teach their peers about their topic in a jigsaw approach.
