22、rds after me.Step VocabularyAsk the students to read the sentences in Activity 1 on page 41, and then pick out the correct ones. At the same time ask them to pay attention to the new words. At last check the answers to Activity 1 with the whole class.For Activity 2, ask the students to work in pairs

23、 to finish the task. If possible, ask them to give their rea-sons for doing so. For Activity 3， give the students more words to help them know that materials are around all of us, and we should use them correctly and reasonably. T: As the saying goes: Birds of a feather flock together or things of o

24、ne kind come together. Now well put the words in Activity 2 in pairs or groups, just like the pairs in Example. If possible, give your reasons to do so.

25、ed the task?Ss: Yes.T: Whod like to read out your answers?S1: Wed like to put air, gas and oxygen together, because all of them are gas. And we put earth, sun and moon together, because all of them are planets.T: Quite right. How about you two boys answers?S2: We put gas, liquid, and solid together,

26、 because we think they are the three states of substance. And we also put contract and expand together. The two words have opposite meanings.T: Im very glad that you can finish the task so quickly and correctly. Well, all of us know that we are living in a material world. Without these materials, wh

27、ether natural or man-made, well have nothing to eat, to live in, to use, to wear and so on. Now, lets look at these words: electricity, iron, metal, steel, air, and glass in Activity 3. You have to tell which of them are natural, which of them are man-made and which of them can be both.S3: Air, iron

28、 and some metals are natural. Steel, some metals and glass are man-made. And electricity can be man-made and natural.T: Why do you think electricity is both man-made and natural?S3: Because in a storm, we can see lightening in the sky. While the electricity we are using in everyday life is from elec

29、tric works. So I think electricity is both man-made and natural.T: Well, its a good answer. OK, can you say some other things that are man-made?Ss: There are too many such things.T: Give us some examples.S4: Cars, machines, man-made satellites, plastics and so on.T: Do you know man-made beauty?

31、ore beautiful than a woman with a pretty face. Step Reading (Passage A: P44)There are three activities in this part: Activity 1: find the correct order to describe the stages of a scientific experiment; Activity 2, find the best title for the passage; Activity 3, answer some questions about the pass

32、age.Task 1: Activity 1 T: Well, if you were an engineer, you would take part in the experiment of making Shen Zhou Flight. What kind of materials would you like to use?S1: Id like to use some materials that are light enough and hard enough, so that the flight can be easily sent up into space, and do

33、esnt get in trouble.T: How can we find such kind of materials?S2: We can do some experiments. We cant use natural materials only; we need both man-made and natural materials.T: Thats right. Now well read a passage about a scientific experiment. Please turn to page 44. Well go through Passage A. When

34、 we are doing a thing, we should do it in an orderly way. Its especially true with a scientific experiment. Now lets see the four words in the table: conclusion, aim, result and method. The four words are about the orders or stages of a scientific experiment. We must know these two words: result and

35、 method. What are the meanings of the other two words?S3: “Aim” should be about what the experiment is for. For “conclusion”, I have no idea.T: Right. “Aim” means purpose or object. For example, he has only one aim in life, that is, to be a millionaire. And for “conclusion”, lets see an example firs

36、t, when you have worked on a maths problem for a long time, but you still cant work it out. So you may make a conclusion that the problem is wrong. Here, “the problem is wrong” is your conclusion. Do you understand?Ss: Yeah!T: Now who can give us some other examples to show the meaning of “aim”?S4:

37、Many people aim to be a millionaire. But I think to serve people is the highest aim.T: What is the correct order of stages to do an experiment?Ss: It should be aim, method, result and conclusion.T: Thats right. Without aim, we dont know where to go; without method, we dont know how to do things well

38、; without result, well draw a blank or gain nothing; without conclusion, well find what weve done is worth nothing. Task 2: Activity 2Ask the students to scan Passage A and find the best title for the passage.T: Please look at Activity 2. What you should do is to scan Passage A and decide which is t

39、he best title for the passage.Give the students some time to do the job and then check the answer.T: Well, whats the best title for the passage?S4: The Reaction of Metals.T: Why?S4: The writer begins the passage by introducing the different uses of different metals. But for the rest part of the pass

40、age, including the table, he / she mainly describes several metals reaction with different substances.T: What a good reason it is! Now, lets look at Activity 3.Task 3: Activity 3Ask the students to read and answer the questions below the passage. Give them some time to do the job. After that, check

41、the answers with the whole class. Step Reading (Passage B: P45)In this part, the students will read the passage and then fill in the table below the passage.There are three Tasks in this part. The first one is to ask the students to find the structure of the passage and finish the table. The second

42、one is to deal with Activity 5. The third one is to finish Activity 6.Task 1: Structure of the passageT: Now, well continue to read Passage B. The title of it is A Simple Scientific Experiment. From the passage we can see how the experiment is done. What is the structure of a description of experime

43、nt? Who can come to the blackboard to write down the structure?S: Let me try.A student comes to the blackboard and writes down the structure.A Simple Scientific Experiment: Introduction Aim Apparatus Method Result ConclusionT: OK. We should notice that there are 3 different reactions which are respe

44、ctively described with method, result and conclusion. Now, please read the passage and then fill in the table. Let the students do the job, and then check the answers with the whole class.T: Well, what is ordinary water according to the experiment?S6: I think ordinary water here means the water that

45、 has not been boiled, and has air in it.T: Right. We also call ordinary water “raw water”. Now whats “Bunsen burner”? We often find it in labs. Now, turn to page 46, and find the picture of Bunsen burner.Task 2: Activity 5T: Now please turn to page 46. Look at Activity 5. Read Passage B again. Compl

46、ete the sentences.After the students finish the sentences, ask some of them to read out the complete sentences and check the answers with the whole class.Task 3: Activity 6This part is about vocabulary study. Let the students read after the teacher, and then work in pairs to find the meanings of the

There are three sentences on it. Can you translate them into Chinese?Let the students translate the sentences into Chin

51、ese.T: OK. In fact, these sentences involve two sentence structures. One is: it is + adj. + to do something. The other is an object clause.

After class, please do Exercises 6, 7 and 8 on pages 92&93. These exercises can help us remember the new words and expressions about scientific experiment. OK, thats all for today. See you next time.Ss: See you.
