Module 5 A Lesson in a Labreading教案Teaching 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. Teaching 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 computer.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 study ingStep 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 is what 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 page44. 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:aim method result conclusionT: 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 knownall of the apparatuses of this experiment?⑵In the second part of the experiment, why must you boil the water? And then why do you addsome 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:Bunsen burner Test tube holderTest tubeThen 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 computer as a task-based activity。

Module 5 A lesson in a lab（第二课时阅读课高一必修1）引言在英语教学中落实新课程标准，就是贯彻执行国家教育部关于课程改革的决定。

新课程标准的三维教学观，结合我校三．五 .三课改理念的精神,具体到英语学科就是要整合发展学生语言技能、语言知识、情感态度、学习策略和文化意识五个方面的素养，培养学生综合运用语言的能力探究学习、合作学习、任务型学习是在新课程标准下实施素质教育的关键环节，所以在我的教学设计里，时时体现着这几种原则。

教学设计理念1、运用任务型语言教学模式，训练培养学生对语言的综合运用，实现目标，感受成功，教学进度整体把握，教学形式不拘一格。

2、课堂以学生为主体，以任务为主线，重视体验参与，教师起到“设计者、研究者、促进者、协调者”的作用。

3、在教学中，突出交际性，注重读写的实用性，要进行情感和策略调整，以形成积极的学习态度，促进语言实际运用能力的提高。

4、课后访谈调查，读写摘记，重视语言运用。

5、正视个体差异，倡导过程激励，以多层次、多角度、多主体的结果与过程并重的评价方式激励进步。

一、学情分析高中年龄段的学生对周围的事物较为敏感，有自己的观点和看法，他们不满足于教科书上的知识，想获得更多的信息。

在英语学习上，他们不只是想把英语作为一门死记硬背的课程来学，更希望能学到知识性和趣味性兼有的内容，从英语学习中获得更多的知识和能力。

二、教学内容分析(一)知识背景及新课程、新教材本单元以化学实验为中心话题，主要内容都是围绕“铁钉在什么条件下生锈”这一中心展开的。

本课是是本单元第二课——“阅读课”，是本单元的重点。

文章的主题是“实验室中的一节课”，其内容介绍了铁钉在三种条件下是否生锈的实验。

本课通过该实验让学生感受化学在日常生活中的体现，激励学生的探索精神，实现梦想。

（二）教学重点难点（1）重点：1．了解实验报告的文体特点并以此指导阅读；2. 训练skimming, scanning, careful reading等阅读微技能；3．对文章深层次的理解赏，学习实验报告的英文表述。

Teaching Plan for Module 5 Book 1(NSE)Topic:A Lesson in a LabTask: Preparing a report on a simple scientific experiment教学内容、目的和要求一、题材内容及任务：本模块是围绕着了解和学会使用与科技、实验有关的词汇和知识而设计的。

INTRODUCTION该部分列举了与科技、实验有关的词汇，并设计了三个练习活动。

通过这三个活动，学生可以初步熟悉这些词的意义，为以后的各项学习活动做好准备。

VOCABULARY AND SPEAKING该部分引入了数字词汇，并设置了有关活动，使学生通过练习，掌握数字词汇的读法。

另外，继续设置了有关科技词汇的练习活动。

GRAMMAR1学习形容词的比较级，主要是引入倍数的表示法。

READING AND VOCABULARY该部分继续引入与本模块主题有关的词汇，并通过两个练习使学生熟悉这些词汇，同时这些练习也为接下去的阅读活动作了铺垫。

介绍了金属的氧化反应，并列出了显示部分金属活动性能的表格。

围绕着课文，编者设计了六个与课文内容和词汇有关的练习。

通过这些练习，学生可以熟悉课文内容和学会使用有关的词汇。

VOCABULARY该部分引入了表示实验仪器的词汇，并介绍了带分数的读法，均配有相关的练习活动。

LISTENING AND WRITING该部分听力内容为实验中师生的对话，配有填写相关实验描述的活动。

GRAMMAR2继续介绍形容词和副词的比较级。

主要介绍了比较级的三种用法：1）表示“越来越……”，2）表示“越……，越……”，3）表示程度的副词（much, a little…）+形容词或副词的比较级。

PRONUNCIATION介绍了特殊疑问句和一般疑问句的句型，要求学生掌握两种句型的语调。

EVERYDAY ENGLISH这一部分介绍了Where do we go from here? Keep the noise down 等五个日常用语，要求学生明确其意义并学会正确使用。

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. Better leave them to the people who are interested in this field of science.Step 4 Detailed reading(Read the passage again. Answer the questions in Part 3 on P44.)(1) Potassium, calcium and sodium. (2) It burns to form an oxide.(3) Magnesium, aluminium and zinc. (4) It has a slow reaction. (5) No, it doesn’t.Step 5 Further reading (Exercises in English Weekly)T: Now read Passage A carefully to choose the best title for it.S: The Reactionof Metals is the best title.Step 6 Language points1. It is hard to think of a world without metals.it是形式主语,真正的主语为to think of a world without metals,这是英语中一个很重要的句型。

Module 5 A Lesson in a LabThe Second Period Listening and SpeakingTeaching goals1. Target language：English numbers2.
