Module 5 A Lesson in a Lab Ⅰ. 模块教学目标Ⅱ. 目标语言Ⅲ.教材分析与教材重组1. 教材分析本模块以“A Lesson in a Lab”为话题，旨在通过模块教学，使学生了解一些基本的科学实验知识，学会怎样写实验报告，并掌握一些相关的词汇与短语，激发学生对科学的兴趣。
此外还要求学生学会读一些大的整数、分数及小数。
从文化的角度来看，鼓励学生了解国外相关科学教学的情况，以扩大学生的知识面，从而激发他们的学习兴趣。
1.1 INTRODUCTION 这部分由三个内容组成。
通过听材料，归纳词语和回答问题这三个形式来完成本部分所涉及到的与科学、实验相关的词语的练习，为以后的各项活动做好准备。
1.2 VOCABULARY AND SPEAKING 这部分设计了一些数字，包括整数、分数和百分数，并通过一些练习让学生熟悉并准确使用英语数字的读法。
1.3 GRAMMAR 1 这部分介绍了形容词比较级中相关倍数的两种主要用法：... times ... than ...和... times as ... as ..., 并通过对比练习来增强学生对这个用法的了解。
1.4 READING AND VOCABULARY 这部分由两篇短文组成。
Passage A 介绍了金属在生活中的重要性，并列举了一些金属在氧气、水及蒸气中的反应及其结果。
Passage B 介绍了A Simple Scientific Experiment，要求学生学习如何描述或写一个科学实验报告。
通过对这两篇文章的学习，学生还能够学会一些科学词汇，有助于今后阅读一些相关的文章。
1.5 VOCABULARY 该部分介绍了带分数的读法，及一些实验仪器的词汇，并配有相关练习。
1.6 LISTENING AND WRITING 这部分听力的内容是实验中的师生对话。
我们能够将此作为对阅读内容在语言技能上的补充。
听力问题的设计本身已经显示了做听力练习的技巧。

BOOK1 Module 5 A Lesson in a LabReading & VocabularyTeaching aims and demands:⒈To learn about some vocabulary and knowledge related to science and experiments⒉To know about some metals and get to know their main uses in our lives⒊To make the students know how to do a simple experiment and write the report about it inEnglish4. To develop students’expression ability as well as reading ability by practicing these twopassages5 To raise students’ interests in science and form the scientific attitude.Teaching key points:⒈To make the students understand and grasp the vocabulary and knowledge related to science and experiments⒉To 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:⒈Communicative Approach⒉Task-based Approach⒊Aural-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 do 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 we match each of the above pictures with the new words, 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 usethese 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 answersPassage 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 do a chemical experiment in a lab successfully? And what is the correct order to describe a scientific experiment?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 45.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?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 computer as a task-based activity。
