Ask the students to scan the three activities in LISTENING AND WRITINGon P46, so that they know what they are going to do, and try to get ready to catch the key words or key sentences when they are listening.T: Now, please turn to page 46. We are going to have a listening. At first, scan the three instructions to know what you are going to do.Several minutes later.T: Do you know what you are going to do?T: What’s the first one?T: What is your prediction?T: Good, this is a correct attitude towards science. Now, we’ll listen to the conversation to find the result. So please listen carefully and write down the key words.Play the recorder for the students to have a first listening. After that, let the students write down their answers using the key words. If possible, ask them to write the whole sentences.T: Now let’s listen and plete the description of the scientific experiment. We’ve known the Aim and Result. What we should focus on is Apparatus, Method and Conclusion. And for Method, we should pay attention to the function words: first, then, next, after that, and lastly. Do you remember?T: OK, let’s listen again.Play the tape recorder again. The students listen to the recorder and plete their sentences.

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.

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. Teaching difficulties:To make students learn how to write an experiment report in EnglishTeaching methods:⒈ municative Approach⒉ Task-based Approach⒊ Aural-oral Approach with the help of the multi-media puter and the recorderTeaching aids:Multi-media puter; Software; PowerPoint; RecorderTeaching procedures:Step 1:Lead-inAt first show the students the picture of a lab with the help of puter.Then 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 puter 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? Andwhat 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, t his is what we’ll study very soon.This step is employed to create a language environment for students’ munication and arouse their interests in reading passage A and passage B on page 44-45Step 3. Re adingPassage AT: Well, let’s read through pas sage 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 page44. Finish this activity by multi-media puter. 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. Thencollect the answers from them. At the same time type out the correct answer on the screen with the puter as follows:T: Now, let’s e 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 “apparat us 〞 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 puter 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 experiment very well, Activity 5 on page 46 can be typed out on the screen with the help of puter as a task-based activity 。

杰克和他弟弟一样高。
【自主学习】
形容词和副词的比较级的用法：
英语中的形容词和副词在表示“比较”概念时要用特别的形式，称为比较级（the Comparative Degree）。
1. 原级比较：表示两者程度相同，用句型“as+形容词/副词+as…”。
否定结构为：not as/so +形容词/副词+as…
E.g: Tom speaks as quickly as his cousin.
汤姆说得和他表兄妹一样快。
2. 比较级
(1) 表示“一方超过另一方”时，用“形容词/副词的比较级+than”的结构表示。
（单音节的比较级
由形容词/副词原形+er构成；多音节词的比较级由more+形容词/副词原形构成。
）
E.g: Our classroom is brighter than yours.
(2) 表示“一方不及另一方”时，用“less+形容词/副词比较级+than”的结构。
E.g: This room is less beautiful than that one.
3. 表示倍数的几个句型：
(1)…倍数+ as + 形容词原级+ as…
(2)…倍数+ 形容词的比较级+ than…
(3)...倍数+ the + n.(size, lengt h, width, height, depth)+of…
4. 在比较句中为了避免重复，通常用that(those),one(ones)代替前面出现的名词。
Eg : A box made of iron is stronger than one made of wood.
5. 比较级的省略现象：
—What do you think of the film?
—Wonderful. I have never seen a better one. （one 后面省略了than that one.）
6. 在形容词比较级前可以用：even, still, much, rather, any, far, by far, a little, a bit, a lot 等词来修饰。
E.g: Are you feeling any better?
