  • Paper, pens.
  • Notes.
Lesson Process:

1. Students will now combine science and language arts! They will work with the results of this unit to write an interesting five-paragraph essay comparing and contrasting the two ecosystems. They will begin with a brainstorming session in groups as to the commonalities and differences between the two.

2. Students begin in groups of 3-4. They will brainstorm for the most complete answers possible to the following questions:
A. What are things that you could compare about the two ecosystems? In which ways are they similar? List as many areas of comparison as possible.

B. What are things that you could contrast about the two ecosystems? In which ways are they different?

C. Make as long a list as possible of descriptive words or phrases you could use to describe these ecosystems or elements of them. Use the mural and your notes for inspiration.

D. What do you think is something fascinating or unique about each ecosystem?

3. Now, show students how to organize their thoughts into an outline:
Paragraph 1: Intro. Thesis statement, including main points.
Paragraph 2: Strongest comparison.
Paragraph 3: Strongest contrast.
Paragraph 4: Secondary comparison
Paragraph 5: summary, restatement of thesis, and include fascinating or unique points worked into a concluding statement.

4. Finally, students work with their brainstorming notes and outlines to write the essays. Choose a few good ones to read to the class.
