    Step 2 Listening and Writing

    1.Activity1 on P46.

    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? First let’s guess / predict the result according to what you have learned in chemistry lesson. Suggested answer:T(本文来自:WwW.hNboxu.cOm 博旭 范文 网:外研版高三英语教案)he weight of the substance will increase,because the metal magnesium burns to form an oxide in air as we have learned in Passage A.

    2.Activity2 on P47.

    Now let`s listen to the dialogue to get the main idea this time and try to find out whether there is a change in weight when the metal magnesium burns in air.

    3.Activity3 on P47.

    Listen again to get more details and try to fill in the blanks.

    Compare the answers and then listen one more time to check the answers.

    Suggested answers:(The students don`t have to write down,because it`t difficult to write down.)

    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,light the Bunsen burner and hold the crucible over it to heat the magnesium.

    Finally, weigh the magnesium again. 【Ref: Function on P48】

    Result: It weighs a little more than before.

    Conclusion: There is a change in weight when magnesium burns in air.

    Step 3 Function

    Ask the students to read through this part silently to understand. Pay special attention to the words and expressions of sequence.

    first, then, next, after that, lastly

    【*Step 4 Task】

    This part can be omitted. Assign another writing task for this module.

    Step 5 Writing

    根据下面的提示,写一篇“观察水的沸腾”的实验报告(100词左右)。

    目的:(1)观察水沸腾时的温度。(2)观察水沸腾过程中的现象。

    器材(apparatus):烧杯(beaker),水,温度计(thermometer),酒精灯(alcohol burner),火柴。

    步骤:(1)在烧杯里盛100g 左右的水。

    (2)在水中放入温度计。

    (3)加热杯中的水,并观察温度计的示数(reading)和水的情况。

    结果:当温度达到100摄氏度时,水面出现大量气泡。

    结论:(1)水在100摄氏度时开始沸腾。

    (2)水在沸腾过程中有大量气泡(bubble)产生。

    【Refer to Passage B】
