lives by examining some key scientific findings and famous scientists.At the end of the unit findings and famous scientists.At the end of the unit studnets will understand that there is more to science studnets will understand that there is more to science than chemistry,physics,biology and so on.than chemistry,physics,biology and so on.2.2.Help students understand that experiment must Help students understand that experiment must follow a particular procedure so that other scientists follow a particular procedure so that other scientists can check the findings by doing the experiment the same can check the findings by doing the experiment the same way and getting the same results.This is the safeguard way and getting the same results.This is the safeguard for the accuracy of scentific resultsfor the accuracy of scentific resultsTeaching Arrangement:Period 1:Warming up(P1);Listening(P41);Project(P47)Period 2:Pre-reading,Reading and comprehending(P1-3)Period 3:Language

diseaseThe Second PeriodKing CholeraBroad Street in 1854Bacteria of cholera Four outbreaks of cholera in the 1830s and 1840s killed many people in England.In 1854,“the most terrible outbreak of cholera which ever occurred in the kingdom”began.It was so violent and sudden that 127people died in the first three days.Group work:1.Do you know how to prove a new idea in scientific research?2.What order would you put the seven in?draw a conclusion think of a method collect results make up a question find a problem analyze the results find supporting evidence repeat if necessary1.Whats the main idea of the passage?A.John Snow was a well-known doctor in London.B.The cause of Cholera was polluted water.C.The source of all drinking water should be examined.D.How did John Snow collect,analyze data and find the cause of the disease and solved it.Task1:Skim and answer the questions2.What helps John Snow find the clue about the cause of the disease?3.When was John Snow able to announce with certainty that polluted water carried disease?A map of London After he found two deaths in another part of London that were linked to the Broad Street outbreak.Task 2:Scanning Read and find out the main idea(or topic sentence)of each paragraph.John Snow wanted to use his knowledgeto solve and find out the cause and cure ofcholera.He got interested in two theoriesexplainingHe needed to prove the second theorywas correct.He marked on a mapJohn Snow looked into the source ofthe waterPara.1Para.2Para.3Para.5Para.6Para.7Polluted water carried the diseaseFinally“King Cholera”was defeatedPara.4The

would like to choose in the future.These questions may help you:What job do you want to do?What education will you need?What personality will be needed?How long will the training take?What work experience would be useful?How will you prepare for this career?Theses expressions may help you:I always wanted to.becauseI might find it difficult to My greatest problem will be to The experience I will need isI need to practiceI will need to be/become patient,creative,hard-working,co-operative,confident,brave,positive,pleasant,polite,determined,energetic,strict withTask 2:Reading and writing CopernicusPre-readingWe know Copernicus was one of the first scientists to use mathematical observations to collect information.He believed the sun is the center of the universe and the earth and other planets went around it.The chart on P.7 shows his theory.Copernicus Revolutionary TheoryRead through the passage,and tell whether the following statements are true or false.1.At Copernicus time,Christian Church was in charge of many western countries.2.Copernicus noticed that observed from the earth,some planets appears in front of or behind the earth.3.Copernicus didnt show his new theory to his friends until he completed it.4.His friends were not interested in his ideas.5.Since he was not afraid of being attacked by the Church,Copernicus published his book as soon as he finished working on it.6.Newton,Einstein,and Hawking are all scientists who made contribution to the study of the universe.TFTFFTRead through the passage again and answer the following questions1.Why was Copernicus mind confused?Because his mathematical calculations led to the same conclution:that the earth was not the center of the solar system2.Why couldnt Copernicus tell the world his theory?Because his theory was against the powerful Christian Churchs idea.If he had done so he would have been punished severely3.How did he prove his theory?He collected observations of the stars and used all his mathemati-cal knowledge to work on the problem.Finally he proved it right.4.Can you describe his theory with a few words?The sun is the center and all the planets go around the sun in the solar system.Read carefully and try to draw the two theories of the universe.Before Copernicus theoryShowing Copernicus theoryThe Earth was stationary at the center of the solar system,and the Sun and planets revolved around it.The Sun is stationary at the center of the solar system,and the Earth and the other planets orbit around it.Analyze the following picture carefully and try to explain how a loop is formed.Discussion:If you were Nicolaus Copernicus,would you have hidden your theory for so many years?Why?As a scientist,Copernicus was more cautious than coward.If he had published his ideas at his time,he would have been killed just as Bruno who was burnt to death because his theory was against the Christian Churchs.Every time when a new idea appears,there are always rejections.Its normal.Scientists should have patience to spread their truth.Writing:Now write a short letter asking Copernicus to publish his idea so everyone can read them.Task 1:Language points 1.revolution&revolutionary e.g.Mao Zedong is the great leader of the Chinese Revolution.Sun Zhongsan is a great revolutionary leader.2.lead to:to result in 导致导致 e.g.Your carelessness will lead to the trouble in the future.3.make sensee.g.No matter how I tried to read it,the sentence didnt make sense.The Fifth Period:Language points and past participle5.reject:e.g.If you dont like Tom,you may reject his gift.
