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 asin 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 byhaving the students say an increasing sequence, eg:3three33thirty-three333 three hundred and thirty-three3, 333 three thousand, three hundred and thirty-three33, 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 practice 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 sametime the teacher have the Ss repeat them after him or her.Then the teacher and the Ss make an analysis about the rules of readingfractions in English together.Finally the teacher ask the Ss to read the rest of the fractions inActivity 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 checkwhat they read.Answers: 1. two-fifths; 2. five-eighths; 3. nine-tenths4.three-eighths;5.five-sixths.Activity 3The teacher should introduce the concept of percentage at first, and then theteacher write down some percentages on the blackboard and read them out in English.Eg: 35%→ thirty-five percent (or: 35 percent); 50 percent equalsa 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 Activity2 as percentages in English .Answers: 1. A quarter is the same as 25%; 2.One third is the same as33.33r%(thirty-three point three three recurring percent); 3.Four-fifths is thesame 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 pointsix six recurring percent); 8. Two-fifths is the same as 40%; 9. Five-eighths isthe 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 .Periods 2 & 3Reading & VocabularyTeaching aims and demands:⒈ To learn about some vocabulary and knowledge related to science and experiments⒉ 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 aboutit in English⒋ 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 practicingthese two passages⒍To raise students’interests in science and form the rigorous scientificattitude.Teaching key points:⒈ To make the students understand and grasp the vocabulary and knowledge related to science and experiments⒉ 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 English Teaching methods:⒈ Communicative Approach⒉ Task-based Approach⒊ Aural-oral Approach with the help of the multi-media computer and the recorder Teaching 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 ingroups: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 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.
