Different metals have different uses, for example, steel is used in cars, and iron is used in electrical equipment.不同的金属有不同的用处，比如说，钢材用于制造汽车，铁用于制造电子设备。

When we use metals, it is important to know how they react with different substances, for example, water and oxygen.当我们使用金属的时候，知道它们和不同物质的反应是很重要的，例如水和氧气。

The reaction of metals with these substances can be put in order. 金属和这些物质的反应是有顺序的。

Here is a table with the metals that react most at the top, and the metals that react least at the bottom.an oxide=another substance + oxygen 氧化=另一种物质+氧气● A Simple Scientific Experiment一个简单的科学实验下面是一种简单的科学实验描述。

But we’ve got a lot of things to do before an experiment. First, we should be clear the aim of the experiment, the apparatus we need and how we can carry it out (we call it “method〞).We watch what’s happening and get the result. Lastly it is important to have a discussion on the result of the experiment. Don’t forget to write d own the conclusion.Aim----apparatus----method---result----conclusionTask 2 Vocabularytest tube [tjuːb] n. 管test tube holder 试管架iron[‘aɪən]铁apparatus[æpə'reɪtəs] n. 设备Bunsen burner [‘bʌnsn] 本生灯nail [neɪrust [rʌst] vi. 生锈n. 锈boil [bɔɪl] vt.& vi. 〔使〕沸腾，开ordinary [‘ɔːdɪn(ə)rɪ] adj. 普通的;一般的;Task 3---Read the first three paragraphs in 1 minute and find out the aim and apparatus of the experiment.1.

Module5 A Lesson in a Lab教案Period 1Introduction & Vocabulary and SpeakingTeaching 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: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 __________(a) as a solid, a liquid and a gas (b) as a solid and a liquid only2. When you heat a metal, it will ___________(a) expand (b) contract3. Steel is mixture of_____________.(a) iron and other substances. (b) iron and oxygen4. _______________ of the earth’s surface is water.(a) Two-thirds (b) 50%5. The distance of the sun from the earth is ______________ kilometers.(a) 25,500 (b) 150,500,5006.The earth is 4.6______________ years old.(a) million (b) billion7. The earth is ______________ the moon(a) twice as large as (b) forty-nine times larger thanThen 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 or man-made, now I’ll show you some cards in my hand, can you tell me which are natural, man-made or both?After this, the teacher can continue to say to the whole the class: Can you give some examples? Then divide the whole class into two big groups to compete. The teacher can ask the Ss to speak out as many examples as possible and write down the words in the table on the blackboard as follows:Finally, ask the Ss to open their books at Page 41 and read the words in the box aloud. If possible, they can look up the words to know what they mean. Of course, the above competition will continue, that is to say, at this moment, the teacher can ask the Ss to put the words in the box on Page 41 in their books in the above table.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 like this:Before dealing with the activity, the teacher had better build up a long number by having the students say an increasing sequence, eg:3 three 33thirty-three333 three hundred and thirty-three3, 333 three thousand, three hundred and thirty-three 33, 333 thirty-three thousand, three hundred and thirty-threeAt 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 pract ice saying the numbers at the top of Page 42 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 the directions.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 them after 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 their own. 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 somepercentages on the blackboard and read them out in English.Eg: 35%→ thirty -five percent (or: 35 percent); 50 percent equals a half.Then 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 three recurring percent); 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. One half 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 the same 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 as 83.33r%(eighty-three point three three recurring percent). Homework:1. Preview the reading part.2. Work in pairs to finish Activities 4& 5 on Page 43 .Teaching aims and demands:⒈ To learn about some vocabulary and knowledge related to science and experiments ⒉ To know about some metals and get to know their main uses in our lives⒊ To make the students know how to do a simple experiment and write the report about it in English ⒋ To deal with all the activities1-6 about passage A and passage B on page 44-45⒌ To develop students’ expression ability as well as reading ability by practicing these two passages ⒍ To raise students’ interests in science and fo rm the rigorous scientific attitude. Teaching key points:⒈ To make the students understand and grasp the vocabulary and knowledge related to science and experiments ⒉ To enable the students to know how to read some passages about simple scientific experimentsTeaching difficulties:To make students learn how to write an experiment report in EnglishTeaching methods:⒈ Communicative Approach⒉ Task-based Approach⒊ Aural-oral Approach with the help of the multi-media computer and the recorderTeaching aids:Multi-media computer; Software; PowerPoint; RecorderTeaching procedures:Step 1:Lead-inAt first show the students the picture of a lab with the help of computerThen design the following questions and ask the students to discuss them in groups:1.Are you interested in doing scientific experiments?2.Suppose you want to do a chemical experiment about some metals, do you think it is necessary to know about how they react with other substances?3.In order to carry out an experiment successfully, what should you prepare for it?This step is to warm up the students and raise their interests to speak English in class. Because all these questions are very close to the students’ daily life and studyingStep 2：Pre-readingTeacher: Since you are interested in doing scientific experiments, now let’s get to know some vocabulary and knowledge related to science and experiments.At the same time I can type out some pictures about some metals on the screen with the help of the computer as follows:⑴potassium(钾) ⑵sodium(钠) ⑶calcium(钙) ⑷magnesium(镁)⑸aluminium(铝) ⑹zinc(锌) ⑺iron(铁) ⑻copper(铜)As I type out each of the above pictures, I can ask the students like this: What’s this? And what can it be used for?At this moment the students’ interests are probably approaching a climax. So I further ask them like this: Do you want to know more about these metals? And do you know how we can use these metals better? Well, this iswh at we’ll study very soon.This step is employed to create a language environment for students’ communication and arouse their interests in reading passage A and passage B on page 44-45Step 3: Re adingPassage AT: Well, let’s read through passage A with the tape of it very quickly to try to catch its main idea. Then finish Activity 2 on page 44 and give your reasons.Next, ask the Ss to read passage A very carefully to find out the answers in Activity 3 on page 44. Finish this activity by multi-media computer. It can be designed as follows:1.Which of the metals in the table reacts the most with oxygen and water?Potassium, calcium and sodium.2.What happens when you heat calcium in oxygen?It burns to form an oxide.3.Which metals react with steam?Magnesium, aluminium and zinc.4.Does iron have a slow or fast reaction with steam?It has a slow reaction.5.Does copper react with water?No, it doesn’t.Passage BT: Well, from passage A we can see how interesting the experiment about the reaction of metals is! But do you know how we can carry out a chemical experiment in a lab successfully? And what is the correct order to describe a scientific experiment?Ask the Ss to look at Activity 1 on page 44 and give them about 2 minutes to discuss it. Then collect the answers from them. At the same time type out the correct answer on the screen with the computer as follows:T: Now, let’s come to see “ A simple scientific experiment”!Then play the tape of passage B for the students and ask them to read the passage with the tape quickly and finish Activity 4 on page 44.In order to lead the students to read the text very carefully, the following task-based questions can be signed to ask them to answer:⑴Can you guess the meaning of the word “apparatus” through the context? Have you known all of the apparatuses of this experiment?⑵In the second part of the experiment, why must you boil the water? And then why do you add some oil to the water?For Question 1, some students maybe feel strange to some apparatuses. If so , the following pictures can be typed out with the help of computer to help Ss to know about:Then in order to make the Ss consolidate what they read in passage B and check if they have understood the aim method result conclusionBunsen burnerTest tube holderTest tubeexperiment very well, Activity 5 on page 46 can be typed out on the screen with the help of computer as a task-based activity 。
