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.

P94 That’s when things started to go wrong. P94... as the lecturers are people who have made real discoveries in their area of science. P49I’m becoming more and more interested in physics. P492. 态度与方法Enable the students to describe an incident in a science class.3.情感态度与价值观Help the students learn how to describe an incident.Help the students learn how to write a description of an experiment according to the outline.二、Teaching important and difficult points 教学重点和难点Help the students discuss incidents that have happened in their science classes.三、Teaching methods 教学方法Discussion and pair work.四、Teaching aids 教具准备A computer and a projector.五、Teaching procedures &ways 教学过程与方式StepⅠ RevisionCheck the students’ homework.For these two exercises, ask the students to read out the complete sentences. T: From Exercise 4, we know that we can use much, a bit, a lot, a little to modify the comparative expressions. Besides these, we have other words to do this. Now please look at the sentences on the screen. Read the sentences and pay attention to the bold face.You have far more imagination than I have.It’s slightly warmer today.She’s actually a good deal older than she looks.Do you feel any better today?She was no older than Zilla.You must go and get some more milk.He is fat, but his brother is still fatter.This book is even more useful than that one.My sister is ten years younger than me.You’re a head taller than Jane.It was one-fourth cheaper than the market price.After the students have finished reading, ask them to make a conclusion of the words to modify the comparative degree.T: By now we’ve learned many words that can modify the comparative degree. What are they?S1: They are much, a lot, far, a bit, a little, slightly, any, no, some, even, still, a head, ten years and so on.T: Yeah, that’s right. Now, that’s all for the home-work. Let’s come to Reading. Step Ⅱ Lead-inT: Do you know this man?S1: He is Ting Zhaozhong, a world-famous Chinese scientist. He once won the Nobel Physics Prize.T: That’s right. He is a top-class scientist. Many outstanding scientists think it is an honor to work with him. What he often says is “I don’t know”. We know science is a serious thing. You can’t be too careful in it. I think this is the real spirit that a scientist and the person who aims to be a scientist should have. Step Ⅲ Reading (P94)Task 1: Fast readingT: Now let’s turn to page 94 to see what happened in the chemistry lab. First, read the three summaries about this passage on page 93. After reading the passage quickly, choose the best one.Give the students some time to read the passage.T: Which one do you think can be the best summary of the passage?S1: No. 1 is the best summary, I think.T: Good.Task 2: Careful readingThe purpose of this task is to answer the eight questions in Exercise 11, and let the students get familiar with some new words in this Module.T: Now, let’s read the questions in Exercise 11, so that you can know what you should do when you are reading. Now read the passage carefully and find the answer to each question. Mark where the answers are and then number them. So that you can find them quickly when you need these answers.Let the students do the job in pairs. One asks the questions and the other answersthem. While the students are asking and answering the questions, walk around the classroom to see if they need any help. And at the same time, collect the answers. Step Ⅳ DiscussionT: Well, you often do some experiments in your science lessons, right? Did any incidents happen? Now I’ll give you some time to discuss the incidents that have happened in your science lessons.After a while.T: Who would like to report an incident that happened before?S1: I’d like to. One morning, we were doing a chemical experiment in the school lab. We fetched some solution(溶液) from the cupboard, including oil of vitriol(浓硫酸), and put them on the table. Wang Hua and Ding Ding were in the front row. Xiao Ming and I were in the second row. Suddenly, Wang Hua turned to say something to me, and turned over the bottle with oil of vitriol by accident. The bottle was not covered! The oil of vitriol splashed. Soon a hole was burned in Xiao Ming’s coat. And his hand was burned to black. He screamed. We were so worried. The teacher ran over to send Xiao Ming to the nearest hospital.Fortunately, nobody else was injured in the incident. However, it taught us a good lesson. Never leave a bottle uncovered on the table.S2: I’d like to tell you about one of the incidents in our chemical experiment. In the experiment, we used Bunsen burner. After the experiment, one of my classmates forgot to cover it. About ten minutes later, a teacher passed the laboratory and smelt the odd smelling. She immediately entered the lab and put out the fire. Fortunately, no further incident was caused. After that all the teachers and students were gathered to have a meeting. The headmaster gave a talk to em-phasize the importance of safety in lab. That’s a good lesson.T: Yeah, if the teacher didn’t notice the incident, it would have been a terrible fire. We often think it’s impossible to make an accident. But as a saying goes, “It’s not too careful to do a thing.” We should always keep the saying in mind. Step Ⅴ Cultural CornerT: In this Module, we’ve learned many things about scientific experiment. Maybesome of you find it interesting, because you are interested in science; while others may find it’s dull, because they prefer art lessons. In our class, who enjoy study-ing science? And why?S1: I like studying science. I like maths best. When I work out a problem, I feel very happy.S2: I like chemistry. It’s very interesting to see that you add one substance to another, and they react and change into a new substance. That is fantastic!T: Knowledge is power. Whatever subjects you enjoy learning, you should devote yourselves to them. Or you won’t make any achievement. Now let’s turn to page 49. Read the passage and answer this question: Why has Mark become more interested in science?Give the students some time to do this in pairs, and then check the answers. T: Are you ready to answer the question?Ss: Yeah!T: Why has Mark become more interested in science?S3: I think there are two reasons. One is that the science facilities are very good in the new school, with laboratories that have all the latest equipment. The other is that they have four chances each term to public science lectures, and the lecturers are people who have made real discoveries in their area of science. I think Mark is a lucky person.T: Yeah. Situations can change a person. In fact, we also have the same chance to learn some knowledge outside class. Channel 10 on CCTV offers a lot of lectures about science and art. Some are given by famous professors. One of my favorite programs is “百家讲坛”. If you often watch it, I believe you’ll benefit from it. Step Ⅵ Summary and HomeworkT: We have learned a lot about scientific experiments. Nowadays, it seems that most people prefer science, because they think science can bring financial benefits, while they do not pay much attention to morality, ethics and love. As a result, there are many disasters and wars in the world. So when we are learning science, we should also pay attention to morality, ethics and love. Today’s homework is to previewPRONUNCIATION and EVERYDAY ENGLISH. OK, time is up. So long, everyone.Ss: So long, teacher.六、板书设计重点词汇：used to, in the area of, be proud of, be supposed to, facility, crucible, balance, tongs, react, stage, mixture, set up重点句式：The hotter the mixture, the quicker the reaction.
