完整教案外研版必修一Module 5 A Lesson in a Lab Period 1Teaching aims:1. To introduce some general science.2. To learn some words related to the theme of this module.3. To develop speaking ability by practicing saying the numbers, especially the fractions. Important and difficult points:1. Arouse the students' interests and love in science.2. Enable the students to understand some elements about the chemistry lab.3. Make the students know how to read the numbers.Teaching procedures:Step 1. IntroductionActivity 1The aim of the activity is to ask the students to finish the quiz about general science to arouse their interest in science.The activity can be done as follows:Firstly, ask the students to go through the following the quiz and make their choice on their own. Quiz: How much do you know about general science?1. Water exists __________.(b) as a solid and a liquid only (a) as a solid, a liquid and a gas2. When you heat a metal, it will ___________(b) contract (a) expand3. Steel is mixture of_____________.(b) iron and oxygen (a) iron and other substances.4. _______________ of the earth's surface is water.(b) 50%(a) Two-thirds5. The distance of the sun from the earth is ______________ kilometers.(b) 150,500,500(a) 25,5006.The earth is 4.6______________ years old.(b) billion(a) million7. The earth is ______________ the moon(b) forty-nine times larger than(a) twice as large asThen put the students in pairs to compare their answers and call back the answers from the class. Finally ask them to listen to the tape about the above quiz and check their answers.Answers: 1. a; 2. a; 3. a 4. a; 5. b; 6. b; 7. b.Activities 2 & 3The teacher can prepare some cards about different things for the class at first. Before showing the students the cards,the teacher can say to the whole class: Things can be divided into three kinds, natural, man-made, and either natural orman-made, now I'll show you some cards in my hand, can you tell me which are natural, man-made or both?1 / 12the divide some examples? Then say to the whole the class: Can you give teacher After this, the can continue towhole class into two big groups to compete. The teacher can ask the Ss to speak out as many examples as possible and writeFinally, ask the Ss to open their books at Page 41 and read the words in the box aloud. If possible, they can look up thewords to know what they mean. Of course, the above competition will continue, that is to say, at this moment, the teachercan ask the Ss to put the words in the box on Page 41 in their books in the above table.Step 2. Vocabulary and SpeakingActivity 1The aim of the activity is to have the students know how to read the long numbers. So the activity can be done likethis:Before dealing with the activity, the teacher had better build up a long number byhaving the students say an increasing sequence, eg:three 3thirty-three33three hundred and thirty-three333three thousand, three hundred and thirty-three 3, 333thirty-three thousand, three hundred and thirty-three33, 333At this time, most of the Ss will know the way of reading these long numbers: where to say “million”, “thousand”, and“hundred”. So in order to consolidate what they just learned, the teacher can practice saying thenumbers at the top of Page42 with the students to make sure the Ss have the correct intonation.Then ask the Ss to go through the rest of the numbers in Activity 1 and find the errors individually according to thedirections.Finally the teacher calls back the answers from the class.Answers: 1)The word “thousand”is missing after “four hundred and seventy”; 2)The word “one”(or“a”) is missing before “hundred million”.Activity 2Firstly, the teacher point at the fractions and say them in English. At the same time the teacher have the Ss repeat themafter him or her.Then the teacher and the Ss make an analysis about the rules of reading fractions in English together. Finally the teacher ask the Ss to read the rest of the fractions in Activity 2 on Page 42 in their books in English on theirown. If necessary, the teacher can write down the correct answers on the blackboard to check what they read.Answers: 1. two-fifths; 2. five-eighths; 3. nine-tenths 4.three-eighths;5.five-sixths.Activity 3The teacher should introduce the concept of percentage at first, and then the teacher write down some percentages onthe blackboard and read them out in English.Eg: 35%→thirty-five percent (or: 35 percent); 50 percent equals a half.2 / 12Then have the Ss practice reading aloud the following percentages: 40%; 55%; 85%.Finally have the Ss work in pairs to describe the fractions in Activity 2 as percentages in English. Answers: 1. A quarter is the same as 25%; 2.One third is the same as 33.33r%(thirty-three point three recurringpercent); 3.Four-fifths is the same as 80%; 4. One tenth is the same as 10%; 5. Three-quarters is the same as 75%; 6. Onehalf is the same as 50%; 7. Two-thirds is the same as 66.66r%(sixty-six point six six recurring percent);8. Two-fifths is thesame as 40%; 9. Five-eighths is the same as 62.5%(sixty-two point five percent); 10. Nine-tenths is the same as 90%; 11.Three-eighths is the same as 37.5%(thirty-seven point five percent); 12.Five-sixths is the same as83.33r%(eighty-threepoint three recurring percent).Step 3. Homework1. Preview the reading part.2.Work in pairs to finish Activities 4& 5 on Page 43.Periods 2 & 3Teaching aims and demands:1. To learn about some vocabulary and knowledge related to science and experiments.2. To know about some metals and get to know their main uses in our lives.3. To make the students know how to do a simple experiment and write the report about it in English.4. To deal with all the activities1-6 about passage A and passage B on page 44-45.5. To develop students' expression ability as well as reading ability by practicing these two passages.6. To raise students' interests in science and form the rigorous scientific attitude.Teaching key points:1. To make the students understand and grasp the vocabulary and knowledge related to science and experiments.2. To enable the students to know how to read some passages about simple scientific experiments.

Who can describe them as fractions?S: a half, two and a quarter, three quarters, thirty and a half, twelve and three tenthsStep 6 PracticeT: Work in pairs. Give your partner five sums. Use numbers over a million. Your partner must find the answers. Work out the answers and then say them in words.Step 7 Homework1. Master the new words we have learned in this class.2. Look, listen, speak and write the larger numbers, fractions and percentages.Period TwoThe General Idea of This PeriodIn this period, we’re going to read a passage on the reaction of metals.Teaching Aims1. Improve the students’ ability of reading comprehension.2. Get the students to have a global understanding of the reading passage.3. Train the students to guess the meaning of a word according to the context.Teaching Important Points1. Train the students’ reading ability.2. Get the Ss to understand the reading text. Teaching Difficult Point How to improve the students’ reading ability.Teaching Methods Fast reading and careful reading to understand the passage correctly. Teaching Aids 1. a tape recorder 2. a multimedia computer 3. chalkboardTeaching ProceduresStep 1 Lead-in(Greet the whole class as usual.)T: We are going to do an experiment today. I need these things to do the experiment:test tubes, Bunsen burner, salt ......When we do an experiment, first of all, we should have an aim.We should use proper methods.We should find the result and draw a conclusion.Have you ever done a scientific experiment?What is the correct order of a scientific experiment?(Show the words on the screen.)T: Put the words into correct order.Step 2 MotivationT: As we know quite well, metals are very useful.What are the different uses of metals?What should we know when using metals?Which reacts most with water, potassium or iron?(Show the three questions on the Bb.)You will have a better understanding of metals after reading Passage A.Step 3 Fast reading(Teacher allows the Ss a few minutes to do fast reading.)T: Who has got the answers?S: Different metals have different uses, for example, steel is used in cars and iron is used in electrical equipment.T: What should we know when we use metals?S: When we use metals, it is important to know how they react with different substances.T: So we must be careful when we use metals.Which reacts most with water, potassium or iron?S: Potassium.T: Do we have to keep in mind how metals react with different substances?S: Yes./No need. It’s enough to have some common sense.We’d better leave them to the experts.

Irish-born Campbell and Japanese Omura won half of the prize for discovering a new drug, avermectin(除虫菌素), showing effectiveness against other parasitic diseases. The Chinese scientist Tu Youyou, an 85-year-old female scientist, was awarded the other half of the prize for the discovery of artemisinin(青篙素), a drug cure for malaria(疟疾) that has saved millions of lives all over the world, especially in the developing world.When the news broke that Tu won the Nobel Prize, there were cheers as well as doubts. It also has highlighted differences in prize-awarding practices between China and the West. Some said the achievement was the result of collective efforts by lots ofChinese scientists, so it was unfair to award the prize only to Tu. Indeed, Chinese science awards are mainly presented to projects, instead of individual scientists. But Western awards tend to honor individual scientists who are the first to come up with a new idea or method. Li Zhenzhen, a researcher of the China Academy of Sciences said that the West believes that the advancement of science comes from individuals’ creative minds.In 1969, Tu started to hold a government project aimed at curing malaria. Tu and her teammates experimented with 380 extracts(提取物〕in 2,000 candidate recipes(候选配方〕before they finally succeeded in getting the pure substance artemisinin. In 20xx, Tu was awarded the Lasker Debakey Clinical Medical Research Award, commonly referred to as “America’s Nobel Prize〞.However, i n China, she is even being called the “three-noes〞winner: no medical degree, no doctorate, and she’s never worked overseas. The fact that Tu has none of these three backgrounds reminds us that science should be more accessible to all. One shall be able to become a scientist no matter what kind of background he or she comes from, as long as one put all his heart into scientific research.1.
