Unit 1 Great scientist
Period 3 A sample lesson plan for Using Language
(COPERNICUS’ REVOLUTIONARY THEORY)
Introduction
Language is learned to be used in and for communication. So in this period after the warming up by
looking and listening students will be listening and answering, discussing future jobs, reading a passage
about Copernicus and copying its expressions, summing up theories and finally writing a letter to
Copernicus.
Objectives
■ To help students read the passage “Copernicus’ revolutionary theory on page 6
■ To help students use the language by reading, listening, speaking and writing
Procedures
1. Warming up by looking and listening
Have you ever heard of a man named Qian Xuesen?
Qian Xuesen (1911- ), a native of Hangzhou, Zhejiang Province, went to the United States to study in
1935. In 1955 he returned to China, and in 1958 he joined the Communist Party.
He served successively as Director of the Institute of Mechanics under the Chinese Academy of
Sciences, Vice-Minister of the No. 7 Ministry of the Machine-building Industry, Vice-Minister of the State
Commission on Science, Technology and Industry for National Defence and Chairman of the China
Association for Science and Technology. He was also elected alternate member of the Ninth through
Twelfth CPC Central Committees.
Qian played a leading role in the research, manufacture and testing of carrier rockets, guided missiles
and satellites, thus making outstanding contributions to the development of China's aerospace industry.
2. Listening and answering
Turn to page 5. Listen to the tape in which Qian Xuesen is being talked about. Listen for information to
answer the questions on listed on page 6.
3. Reading and copying
Now it’s time to read the text COPERNICUS’ REVOLUTIONARY THEORY and underline all the
expressions useful to you at the same time. And after class write a short passage making use of the
expressions underlined.
Expressions from COPERNICUS’ REVOLUTIONARY THEORY
confuse one’s mind, make sense, in the sky, punish…for…, suggest an idea, make the world, for
that reason, move backward, go forward in a loop, appear bright, think long and hard about…,
find an answer, collect observations of…, use one’s knowledge to, show …to…, make change
to…, place…at the center of…, publish one’s idea, be attacked by…, lie dying, reject one’s theory,
be against one’s idea, build… on the base of…, replace the idea of…, fall to earth, create…as…, a
direct link between…and…
4. Summing up theories
Next 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’ theory
The earth is the center of the universe. The earth is not the center of the universe.
God makes 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 Earth's mass and of
the lunar orbit.
2) All the planets move along orbits whose center is the Sun, 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 small.
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 seems making (its apparent moving during daytime, and its annual moving
through the Zodiac) are nothing else than effects of the Earth's 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' movements.
(2) Making a plan of writing a letter to Copernicus
Beginning (self-introduction)
Paragraph 1 (reason 1 and evidence)
Paragraph 2 (reason 2 and evidence)
Summing up (persuasion )
6. Closing down by making a debate
To end our studies of Copernicus’ theories we shall make a debate whether the Sun is 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 Copernicus
1)
The
center
of
the
Earth
is
not
the
center
of
the Universe.
2)
All
the
planets
