Module 5 A Lesson in a Lab Listening , speaking and writing教案

Teaching aims: 1. To learn to catch the related information from what they hear and understand the meaning of some expressions by context. 2. To enable the Ss to recognize the basic differences about the intonation of Wh-questions and Yes/No questions from what they hear.

Important and difficult points: 1. Enable the Ss to recognize the basic differences about the intonation of Wh-questions and Yes/No questions according to what they hear. 2. Have the Ss understand the exact meaning of some sentences by context. Teaching procedures: Step 1. Listening and Writing It is necessary for a teacher to give the Ss a brief indication before listening. For this listening, the teacher can say to the Ss:

We are going to listen to a dialogue that takes place in a lab. A teacher helps a student do an experiment. In this experiment, the metal magnesium burns in air. Is there a change in weight when this metal burns in air? Let’s guess / predict.

After the necessary indication, give the Ss very clear directions and requirements to listen. The teacher can continue to say: Now let’s listen to the dialogue. Try to find out whether there is a change in weight when the metal magnesium burns in air. At the same time, pay attention to the information related to the following:

Aim:____________________________________________________________ Apparatus:_______________________________________________________ Method:_________________________________________________________ Result:__________________________________________________________ Conclusion:______________________________________________________ Then begin to play the tape once and ask answers from the whole class. And then ask the Ss to finish Activity 2 on Page 47.

Play the recording again and ask the Ss to complete the above description on their own, and then to check their answers in pairs. Before replaying the recording, of course, had better remind the Ss how they usually write up science experiments, that is, completing the description involves some careful reading for specific information and reorganizing the information. Answers: Aim:

to find out if there’s a change in weight when magnesium burns in air.

Apparatus: Magnesium, Bunsen burner, a balance, a crucible. Method: First, put the magnesium in the crucible. Then put the crucible on the balance and weigh it. Next, heat the magnesium. Light the Bunsen burner and hold the crucible over it. Finally, weigh the magnesium again. Result: It weighs a little more than before. Conclusion: There is a change in weight when magnesium burns in air. Step 2. Everyday English Firstly, ask the Ss to go through the everyday English on Page 48 and choose the correct meanings individually. Then tell the Ss where these everyday English sentences from——they are from the above

listening. Now replay the recording, ask the Ss to check what they chose. Answers: 1) a;

2) b;

3) a;

4) b;

5) a. Step 3. Pronunciation At first,

organize the Ss to listen to the recording, at the same time, give them the direction to listen and ask them to pay attention to the intonation of Wh-questions and Yes/No questions. Then play the tape for the class and ask them again After that, help the Ss to summarize the basic intonation of Wh-questions and Yes/No questions. Answers: Wh-questions often fall at the end. Yes/No questions often rise.

And then play the tape again and ask the Ss to imitate it. Finally, give the Ss more sentences to practice. Step 4. Homework Revise the whole Module 5 and begin to preview Module 6.
