This lesson plan would go great as an addition to a unit on oceans. (I have a full unit on oceans available in my store, this is just one of the many lessons). This lesson could also be used on it's own to teach students about ocean food webs. To teach this lesson you will need the book t by Paul Fleisher called Ocean Food Webs. (You could teach the lesson without the book, and guide the students through the discussion questions by just referring to the book since an answer key is included.) This lesson includes a detailed lesson plan instructing students all about ocean webs, a worksheet where students can demonstrate their understanding by creating their own ocean web, and discussion questions that go along with the book Ocean Food Webs to give students a deeper understanding of ocean food webs.
