9、, a direct link betweenand4. Summing up theoriesNext we shall do some scientific research: to sum up the two theories of the universe with the help of the text.Before Copernicus theory Showing Copernicus theoryThe earth is the center of the universe. The earth is not the center of the universe.God m

10、akes the world. God does not make the world. 5. Writing a letter to Copernicus(1)Reading about theories by Copernicus 1) The center of the Earth is not the center of the Universe, but only the center of the Earths mass and of the lunar orbit.2) All the planets move along orbits whose center is the S

11、un, therefore the Sun is the center of the World. (Copernicus was never certain whether the Sun moved or not, claiming that the center of the World is in the Sun, or near it.)3) The distance between the Earth and the Sun, compared with the distance between the Earth and the fixed stars, is very smal

12、l.4) The daytime movement of the Sun is only apparent, and represents the effect of a rotation that the Earth makes every 24 hours around its axis, always parallel to itself.5) The Earth (together with its Moon, and just like the other planets) moves around the Sun, so the movements that the Sun see

13、ms making (its apparent moving during daytime, and its annual moving through the Zodiac) are nothing else than effects of the Earths real movements.6) These movements of the Earth and of the other planets around the Sun can explain the stations, and all the particular characteristics of the planets

14、movements.(2) Making a plan of writing a letter to CopernicusBeginning (self-introduction)Paragraph 1 (reason 1 and evidence)Paragraph 2 (reason 2 and evidence)Summing up (persuasion )6. Closing down by making a debateTo end our studies of Copernicus theories we shall make a debate whether the Sun i

15、s the center or the Earth is the center, of the universe. The class will be cut in two parts, one for Copernicus, the other against Copernicus. Now take five minutes to get necessary facts and arguments.For Copernicus Against Copernicus1) The center of the Earth is not the center of the Universe.2)

16、All the planets move along orbits whose center is the Sun.3) The distance between the Earth and the Sun is very small.4) The daytime movement of the Sun is only apparent.5) The Earth moves around the Sun.1) The center of the Earth is the center of the Universe.2) All the planets move along orbits whose center is the Earth.3) The distance between the Earth and the Sun is very big.4) The daytime movement of the Sun is just obscure.5) The Sun moves around the Earth.
