Description
"Mars—Twin Brother of Earth" PPT Courseware 2
think about it
Why does the text call Mars and Earth twins? Ask students to read the text freely with questions.
Briefly analyze and communicate in the group, divide the text into levels, and summarize the main ideas.
In the first paragraph (1), the "twin brothers" speculate that there is water and life on Mars.
The second paragraph (2-5) speculates on two sources of water on Mars.
The third paragraph (6-8) explains why water can remain on Earth and support life but not on Mars.
Ask the students to read the first paragraph freely and think about how they can see that Mars and the Earth are "twin brothers."
The two brothers look so much alike - the same Antarctic and North Pole, the same mountains and canyons, the same white clouds, dust storms and tornadoes, the same four distinct seasons, and even the length of a day is almost the same.
Which sentence can prove the credibility of the inference?
Scientists have studied and analyzed photos of Mars and found that there are dry river beds on Mars that are hundreds of kilometers wide, far wider than the Amazon River on Earth today.
Mars and the Earth are both planets with similar environments and similar sources of water. Why can the water on the Earth not only survive, but also give birth to life? And there may be more water on Mars than the Earth, so why can’t it be retained? ?
Text summary
