11、our friends and I like my job very much.S: Id like to be an expert in environment. You see, with the development of industry, our globe is seriously polluted. Dirty water, polluted air, and loud noise make our living conditions worse. I think we should leave a beautiful world to the next generation.

12、T: Yes, someone predicted that the last drop of water in the world would be the tear of human beings. I think all of us should pay attention to our environment, and make our contributions to improving the environment.S: Im so interested in physics. And I have read Stephen Hawkings A Brief History of

13、 Time twice.I hope I will be a scientist like him. As we all know, the development of our society will go hand in hand with the development of science.T: Yeah, I cant agree with you more. Science plays an important part in the development of our society. There are so many examples in the history of

14、human beings.Ss: .T: Im so glad to share your dreams. Your ambition and careful thoughts really leave a good and amazing impression on me. I like them. In this unit, you will learn something about “Great scientists”. Maybe you will know what you need in your efforts to realize your dreams after we t

It is not Tom but you who are to blame.7. In 1995, the Chinese government put forward a plan for “rejuvenating th

21、e nation by relying on science and education”.And it has helped Chinese scientists make many breakthroughs.8.Have you drawn any conclusion after you read this passage?T: Well done. So much for the learning of the new words and expressions. Step 4 BrainstormingT: Now lets come to the title of this un

22、it Great scientists. When we talk about great scientists, what will come into your mind(s)?We will go on our competition.S1: Madame Curie, who got two Nobel Prizes, one for physics and the other for chemistry, is really outstanding among all the women scientists.S2: It reminds me of the great invent

23、or named Thomas Alva Edison and one of his famous sayings “Genius is one percent inspiration and ninety-nine percent perspiration.”S3: Yes, we lead a better life now with the help of science. Without Edison, maybe now we are still living in a dark world. They really make our life easier and more com

24、fortable.S4: I also think of one of the quotes from Albert Einstein, “Imagination is more important than knowledge.”S5: All the scientists are devoted to the career that they choose, and they set good examples to us in our work. S6: Take all the scientists for example, if we want to be successful in

25、 the future, we should not only learn something from our textbooks, but also take part in social practice and get close to nature to learn more about it.S7: I like plants very much. I just think of the two key scientists in the field of botany, Carl Linnaeus and Joseph Banks. The former one laid the

26、 foundation for the classification of plants, while the latter one also made great contributions to the development and direction of botany.Ss: .T: Im glad to see that you have a great deal of previous knowledge of famous scientists in the world.Step 5 Previous knowledgeT: Now lets match some of the

27、 great scientists with their famous discoveries, inventions or theories. Let me see who is the quickest in mind and action and can get all the answers correct.Famous scientistsDiscoveries/Inventions/TheoriesA. Isaac Newton1.Evolution (進(jìn)化論)B. Charles Darwin2.Discovery of Radium（鐳）C. Madame Curie3.New

Zhang Heng8.The earth moves around the sun.(Check the answers with all the students: A3, B1, C2, D5, E4, F8, G7, H6.)T: Since you have a

29、better understanding of some of the great scientists, lets play a game. Please work in groups and describe one of the great scientists, and then let other students guess who you are talking about.Group 1: In the eighteenth century, there lived a great scientist who conducted a number of experiments

30、in which he showed what electricity is. Once he did a famous kite experiment on a stormy day, and proved that lightening and electricity are the same thing.S: Benjamin Franklin.Group 2: It is said that this English gentleman was sitting in his garden one day when suddenly he was hit by a falling app

31、le. The story is probably not true, but this man did mention that he got one of his best-known ideas while watching apples fall from a tree. His name makes you think that he was not too interested in old things. He discovered the force of gravity, and he drew up a system of how objects move. His law

32、s for motion are still used in physics today, at least in schools and universities. S: Sir Issac Newton.Group 3: Food is what sets this great mind on fire. Rice, to be exact. This great mind has spent most of his life looking for ways to help farmers grow more rice so that all of us will have enough

33、 food to eat. He is known as the father of modern rice, but because of his long friendship with all the farmers in China, he would rather be known as “the farmer”.S: Yuan Longping.Group 4: He was born on 8 January 1942 in Oxford, England. He has worked on the basic laws which govern the universe. He

34、 showed that Einsteins General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. He has three popular books published: his best seller A Brief History of Time, Black Holes and Baby Universes and Other Essays and most recently in 2001, The U

35、niverse in a Nutshell.S: Stephen Hawking.Ss: .T: Well done.Step 6 QuizT: You have already known some information about some of the great scientists. Now lets do a quiz, trying to find out who these scientists are.Quiz Questions1. Which scientist discovered that objects in water are lifted up by a fo

36、rce that helps them float?2. Who wrote a book explaining how animals and plants developed as the environment changed?3. Who invented the first steam engine?4. Who used peas to show how physical characteristics are passed form parents to their children?5. Who discovered radium?6. Who invented the way

37、 of giving electricity to everybody in large cities?7. Who was the painter that studied dead bodies to improve his painting of people?8. Who invented a lamp to keep miners safe underground?9. Who invented the earliest instrument to tell people where earthquakes happened?10. Who put forward a theory

38、about black holes?Check the answers with the students.1.Archimedes2.Charles Darwin3.James Watt4.Gregor Mendel5.Madame Curie6.Faraday7.Leonardo davinci8.Humphrey Davy9.Zhang Heng10.Stephen HawkingT: Please work in groups and have a discussion to find as much information as possible about these ten gr

39、eat scientists.(The teacher had better join in the discussion and give them some guidance whenever necessary. After the discussion, ask some students to give a short report about what the group have discussed.)(Refer to the information about these scientists below, and various answers are possible.)

40、Step 7 PracticeT: Today we have learned a lot about great scientists in the world. We can learn from them to live our dreams. And we teachers are too willing to help you. In your opinion, what should our school /teachers/students do to tap the students potential?S: Our school should give the student

41、s more chances to take part in social practice.S: Our teachers should help the students use their imaginations.S: We students should solve the problems on our own.(Ask more students to give their opinions. The teacher should encourage them, join them, praise them, and make comments on their ideas.)S

42、tep 8 Discussion (Group Competition)T: Your ideas are so wonderful and amazing. I admire them very much. Now lets come to our topic.Topic 1: What can you learn from these scientists?Topic 2: What qualities should we have to be a successful man?(Give the students several minutes to have a discussion.

43、 Then let them have a group competition.)Step 9 Summing up T: In this period, we have talked a lot about great scientists. You have a lot of previous knowledge and you are full of imagination and creativity. Those scientists set good examples to us. And I think all of us are happy about learning mor

44、e of them. After class, its better to read some books about them and you can surf the Internet to get more information. And Id like you to make a “Scientists Album” in the following week.The Design of the Writing on the BlackboardUnit 1Great scientistsPeriod 1Welcome to the UnitBrainstormingResearch

Why?2.Fill one glass with fresh water and another glass with salt water. Put an ice cube in each glass. What happens? Why?3.Find

46、 out as many famous sayings from those scientists as possible.Reference for Teaching1.Charles Darwin was born in Shrewsbury (shropshire) to a moderately wealthy family with a strong intellectual heritage. His grandfather, Erasmus Darwin, was a physician, poet and biologist who laid some of the groun

47、dwork for the grandsons revolutionary ideas. Charles attended Christs College at Cambridge with initial thoughts of entering the clergy, but soon took up studies in biology, zoology and geology. From 1831 to 1836, he served as a naturalist aboard the HMS Beagle on its scientific mission to South Ame

48、rica and the Pacific. Back in England, he published a series of scientific treatises which established his reputation as one of the prominent thinkers of his day. From 1842 onwards, he lived on a country estate in Kent and pursued his studies among its gardens and livestock.By 1844, he had written t

49、he initial draft of his groundbreaking treatise on evolution and natural selection. However, he left this work unpublished for several years, preferring to refine and elaborate its core ideas. In 1858, he read a forthcoming paper by a fellow scientist Alfred Russell Wallace whose thesis closely para

50、lleled Darwins own unpublished ideas, an event which pushed Darwin to go public with his own research.Both Wallaces and Darwins papers were presented to the Linnean Society in a famous July, 1858 meeting. Darwin published The Origin of Species by Means of Natural Selection in 1859, sparking decades

51、of contentious debate which ultimately led to the universal scientific recognition of Darwins thesis. In later years, he developed his ideas further in monographs on different types of plant and animal life.Notes: Shrewsbury: 什魯斯伯里英國(guó)英格蘭西部城市physician: 內(nèi)科醫(yī)生 (注意區(qū)分physicist, 物理學(xué)家) revolutionary: 創(chuàng)新的HMS:

52、 （英國(guó)）皇家海軍艦船 (Her/His Majestys Ship)treatises: 論文2.Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo) in Oxford, England. His parents house was in north London, but during the Second World War Oxford was considered a safer place to have babies. When he was eight

53、, his family moved to St Albans, a town about 20 miles north of London. At eleven Stephen went to St Albans School, and then on to University College, Oxford, his fathers old college. Stephen wanted to do Mathematics, although his father would have preferred medicine. Mathematics was not available a

54、t University College, so he did Physics instead. After three years and not very much work he was awarded a first class honours degree in Natural Science.Stephen then went on to Cambridge to do research in Cosmology, there being no-one working in that area in Oxford at the time. His supervisor was De

55、nis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge. After gaining his Ph.D. he became first a Research Fellow, and later on a Professorial Fellow at Gonville and Caius College. After leaving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Ma

56、thematics and Theoretical Physics, and since 1979 has held the post of Lucasian Professor of Mathematics. The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas, who had been the Member of Parliament for the University.It was first held by Isaac Barrow, and then in 166

57、3 by Isaac Newton.Stephen Hawking has worked on the basic laws which govern the universe.With Roger Penrose he showed that Einsteins General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results indicated it was necessary to unify

58、 General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century. One consequence of such a unification that he discovered was that black holes should not be completely black, but should emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has no edge or boundary in imaginary time. This woul
