And the passage tells the readers the scientific idea in order of time. So a timeline is helpful for the students to better grasp the main idea of it.
The earth itself and the living things on it are all very important to us human beings. So we should protect the earth, but how? So the students are to discuss what we can do to protect the earth according the development of the earth and life. The students can brainstorm as many ideas as possible. The students’ performance will be evaluated after and according to their presentation.
