1、Unit 1Great scientistsBrief Statements Based on This UnitThis unit centers on Great scientists, including some scientists both at home and abroad like John Snow and Copernicus.The students should be encouraged to practise talking about these scientists.The whole unit can be divided into seven parts:
2、 warming up, reading, listening and speaking, language focusing, reading and writing, grammar, and assessment.In warming up, there is a quiz for the students to do, which will arouse the students interest in knowing about the famous scientists and help the students to know science is very important
3、in our daily life. Group discussion and brainstorming will be used in this period to help the students to communicate with each other using their previous knowledge.In the reading passage, the students will learn about John Snow, who defeats “King Cholera”, and get a general idea about how to examin
4、e a new scientific idea. This will help the students to form their own attitude towards science.In learning about language, the students are encouraged to learn the following words and expressions: engine, characteristic, radium, theory, scientific, examine, conclude, analyze repeat, defeat, attend,
5、 expose, cure, control, absorb, severe, valuable, blame, immediately, handle, announce, instruct, virus, construction, contribute, positive, movement, backward, complete, enthusiastic, spin, reject, view, steam engine, put forward, draw a conclusion, in addition, link.to., be strict with, lead to, m
6、ake sense, point of view.While practising using the language, the students will learn about Copernicus Revolutionary Theory, and their skills of reading, speaking and writing will be improved.In listening and speaking, more chances will be given to the students to learn about other scientists and th
7、eir spirit. The students are encouraged to make up their mind to make contributions to science.The students will be asked to write a letter to Copernicus on the basis of the understanding of the text. The letters are sure to be full of imagination and creativity.Assessment will help the students to
8、look back what they have learned and focus on the difficult and important points.So, this unit will be divided into seven periods as follows: Period 1Welcome to the Unit Period 2ReadingPeriod 3Listening and SpeakingPeriod 4Reading and WritingPeriod 5 GrammarPeriod 6Language FocusingPeriod 7Assessmen

13、urage the students to learn about some great scientists and their great achievements and how science helps to improve our society and change our life. Meanwhile, inspire the students to learn from the scientists and form their positive attitude towards science.Period 1Welcome to the UnitThe General
14、Idea of This PeriodThe unit centers on “great scientists”. This is the first period of this unit. During this period, the students should be encouraged to give their previous knowledge of some of the famous scientists, participate in the activities in class and try to get more information from the d
15、iscussion. They will take part in different forms of activities, including pair work, group work, competition, and quiz. Group competition will be carried out all through the class.Words and expressions in this unit will help the students to talk about the topic “great scientists”. So at the beginni
16、ng of this period, the teacher should spend some time training the students to read them and help the students pronounce them correctly. The students are encouraged to learn the new words in groups by themselves, using dictionaries and other reference books. Then more time should be given to the stu
17、dents to get familiar with the words and expressions. Lastly, several sentences will be given to the students to help them to know how to use some of the phrases.This unit is about “great scientists”, so from the very beginning, the teacher can encourage the students talk about their dreams in the f
18、uture. Then the teacher can let the students brainstorm something about great scientists. The students are free to say anything that they know. The students will be quite interested in this topic. This activity gives the students a chance to express their feelings about their favorite scientist. At
19、the same time, this activity can stir the students enthusiasm in science.Then the teacher can have the students match the famous scientists with their discoveries, inventions or theories, making sure that they have some common sense about some world-famous scientists.Later the students will be divid
20、ed into several groups, describe one of the great scientists and let other students guess who he or she is talking about. In this way, the students should learn to organize their own sentences and express their ideas clearly.After that, the students will feel comfortable to do the quiz in the text.
21、The students should be encouraged to give more information about these ten scientists.Meanwhile, the students interest in scientists and science should be cultivated. So two topic discussion questions, as well as the practice exercises are designed.The post-class activities are designed to arouse th
22、e students interest in science and encourage them to “DIYdo it yourself” in their daily life if they have some doubt in some areas.Teaching Important PointsHave the students discuss great scientists.Encourage the students to hold their views about their future career.Understand and learn the followi
23、ng words and expressions: engine, characteristic, radium, theory, scientific, examine, conclude, analyse, repeat, defeat, attend, expose, cure, control, absorb, severe, valuable, blame, immediately, handle, announce, instruct, virus, construction, contribute, positive, movement, backward, complete,
24、enthusiastic, spin, reject, view, steam engine, put forward, draw a conclusion, in addition, link.to., be strict with, lead to, make sense, point of view.Teaching Difficulties What can we learn from the scientists?What should we do in our daily life to develop our interest and love for science?Teach

So much for the learning of the new
43、 words and expressions. Step 4 BrainstormingT: Now lets come to the title of this unit 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 rea
44、lly outstanding among all the women scientists.S2: It reminds me of the great inventor 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 no
45、w we are still living in a dark world. They really make our life easier and more comfortable.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
46、in our work. S6: Take all the scientists for example, if we want to be successful in 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 scient
47、ists in the field of botany, Carl Linnaeus and Joseph Banks. The former one laid the 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 f
48、amous scientists in the world.Step 5 Previous knowledgeT: Now lets match some of the 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

50、 answers with all the students: A3, B1, C2, D5, E4, F8, G7, H6.)T: Since you have a 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 eigh
51、teenth century, there lived a great scientist who conducted a number of experiments 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 g
52、entleman was sitting in his garden one day when suddenly he was hit by a falling apple. 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 d
53、iscovered the force of gravity, and he drew up a system of how objects move. His laws 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 lif
54、e looking for ways to help farmers grow more rice so that all of us will have enough 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 19
55、42 in Oxford, England. He has worked on the basic laws which govern the universe. 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. He has three popular books published: his best seller A Brief History of Ti
56、me, Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe 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.Qui

60、ups and have a discussion to find as much information as possible about these ten great 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
61、 to the information about these scientists below, and various answers are possible.)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 /teac
62、hers/students do to tap the students potential?S: Our school should give the students 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 teache
63、r should encourage them, join them, praise them, and make comments on their ideas.)Step 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
64、have to be a successful man?(Give the students several minutes to have a discussion. 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 sc
65、ientists set good examples to us. And I think all of us are happy about learning more 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

His grandfa
68、ther, Erasmus Darwin, was a physician, poet and biologist who laid some of the groundwork 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
69、 served as a naturalist aboard the HMS Beagle on its scientific mission to South America 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 Ke
70、nt and pursued his studies among its gardens and livestock.By 1844, he had written the 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 fort
71、hcoming paper by a fellow scientist Alfred Russell Wallace whose thesis closely paralleled 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 publ
72、ished The Origin of Species by Means of Natural Selection in 1859, sparking decades 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: Sh

His parents house was in north London, but during the Se
74、cond World War Oxford was considered a safer place to have babies. When he was eight, 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
75、, although his father would have preferred medicine. Mathematics was not available at 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,
76、there being no-one working in that area in Oxford at the time. His supervisor was Denis 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 lea
77、ving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics 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
78、 of Parliament for the University.It was first held by Isaac Barrow, and then in 1663 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 B
79、ig Bang and an end in black holes. These results indicated it was necessary to unify 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 compl
80、etely 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 would imply that the way the universe began was completely determined by the laws of science.His many publications include The Large
81、Scale Structure of Spacetime with G F R Ellis, General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravity, with W Israel.Stephen Hawking has two popular books published: his best seller A Brief History of Time, and his later book, Black Holes and Baby Universes and Oth
82、er Essays.Professor Hawking has twelve honorary degrees, was awarded the CBE in 1982, and was made a Companion of Honour in 1989.He is the recipient of many awards, medals and prizes and is a Fellow of The Royal Society and a Member of the US National Academy of Sciences.Stephen Hawking continues to
83、 combine family life (he has three children and one grandchild), and his research into theoretical physics together with an extensive programme of travel and public lectures.3.Humphry Davy, a woodcarvers son, was born in Penzance in 1778. After being educated in Truro, Davy was apprenticed to a Penz
84、ance surgeon.In 1797 he took up chemistry and was taken on by Thomas Beddoes, as an assistant at his Medical Pneumatic Institution in Bristol.Here he experimented with various new gases and discovered the anesthetic effect of laughing gas (nitrous oxide).Davy published details of his research in his
85、 book Researches, Chemical and Philosophical (1799).This led to Davy being appointed as a lecturer at the Royal Institution.He was a talented teacher and his lectures attracted large audiences.In 1806 Davy published On Some Chemical Agencies of Electricity. The following year he discovered that the
86、alkalis and alkaline earths are compound substances formed by oxygen united with metallic bases. He also used electrolysis to discover new metals such as potassium, sodium, barium, strontium, calcium and magnesium.Davy was now considered to be Britains leading scientist and in 1812 was knighted by G
87、eorge .With his assistant, Michael Faraday, Davy travelled abroad investigating his theory of volcanic action.In 1815 Humphry Davy invented a safety lamp for use in gassy coalmines, allowing deep coal seams to be mined despite the presence of firedamp (methane).This led to some controversy as George
88、 Stephenson, working in a colliery near Newcastle, also produced a safety lamp that year. Both men claimed that they were first to come up with this invention.One of Davys most important contributions to history was that he encourage manufacturers to take a scientific approach to production.His disc
89、overies in chemistry helped to improve several industries including agriculture, mining and tanning.Sir Humphry Davy died in 1829.4.Leonardo da Vinci(b.1452, Vinci, Republic of Florence now in Italyd.May 2, 1519, Cloux, Fr.), Italian painter, draftsman, sculptor, architect, and engineer whose genius
90、, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal.His Last Suppe (1495-1497) and Mona Lisa (1503-1506) are among the most widely popular and influential paintings of the Renaissance.His notebooks reveal a spirit of scientific inquiry and a mechanical inventivene
91、ss that were centuries ahead of his time.5.Madam Curie is a French professor of physics.She was born in Poland in 1867.In 1891 she went to study in Paris University because at that time women were not admitted to universities in Poland.When she was studying in Paris, she lived a poor life, but she w
92、orked very hard.In 1895 she married Pierre Curie, and then they worked together on the research into radioactive matter.They discovered two kinds of radioactive matterpolonium and radium.In 1904 she and her husband were given the Nobel Prize for physics.In 1906 Pierre died, but Marie went on working
93、.She received a second Nobel Prize for Chemistry in 1911.So she became the first scientist in the world to win two Nobel Prizes.6.James Watt: British engineer and inventor who made fundamental improvements in the steam engine, resulting in the modern, high-pressure steam engine (patented 1769).7.Gre
94、gor Mendel was an Austrian botanist and founder of the science of genetics.Through years of experiments with plants, chiefly garden peas, he discovered the principle of the inheritance of characteristics through the combination of genes from parent cells.8.Archimedes: Greek mathematician, engineer,
95、and physicist.Among the most important intellectual figures of antiquity, he discovered formulas for the area and volume of various geometric figures, applied geometry to hydrostatics and mechanics, devised numerous ingenious mechanisms, such as the Archimedean screw, and discovered the principle of
96、 buoyancy.9.Michael Faraday (September 22, 1791August 25, 1867) was a British scientist(a physicist and chemist) who contributed significantly to the fields of electromagnetism and electrochemistry. He also invented the earliest form of the device that was to become the Bunsen burner, which is used
97、almost universally in science laboratories as a convenient source of heat.Michael Faraday was one of the great scientists in history.Some historians of science refer to him as the greatest experimentalist in the history of science.It was largely due to his efforts that electricity became a viable technology.The SI unit of capacitance, the farad(symbol F) is named after him.
