精彩课堂
Stepl 学习理解
活动一：感知与注意
1.Appreciate and discuss.
Show some pictures about museums to students and ask them to discuss the following questions. ·Have you ever visited a museum Do you know about Pictures 1~4
·What can you see and what can you doin museums Suggested answers:
·The Palace Museum,National Museum of China,China Science and Technology Museum, Shanghai Natural History Museum.
(
·
)See exhibitions,learn about new inventions,immerse ourselves in a world of wonder,..
2.Ask students to learn about the cultural note of the City of Science and Industry.
Located in Paris,France,the City of Science and Industry is the biggest science museum in Europe. The goal of the museum is to spread scientific and technical knowledge among the public, particularly the youth,and to promote public interest in science,research,and industry. Attractions include a planetarium,a submarine,an IMAX theatre and special areas for children
and teenagers,where games,interactive exhibits,and experimental areas allow them to really get their thinking caps on to explore.
【设计意图】通过欣赏不同类型博物馆的图片和讨论，以及了解巴黎科学工业城的背景知识，
加深学生对博物馆的了解，激活已有知识，自然导入本课话题，提高学生对新知的好奇心。 3.Pre-listening.
(1)Ask students to look at the photos in Activity 1 and discuss the following questions. ·What are the people doing in each photo
·What do these activities have to do with science
Suggested answers:
·In Photo A,a boy is speaking to a giant dish.
In Photo B,a girl is playing a giant piano keyboard with her feet. In Photo C,a boy is looking at a blue screen.
In Photo D,a girl is standing in a hall of mirrors where she can see herself reflected thousands of times.
In Photo E,a boy is standing in front of a white light.
·Photo A:I think the dish in this exhibition is related to sound.Maybe the boy is whispering into the smaller circle and the dish can make his voice louder.
Photo B:This looks like a piano you play with your feet.Maybe it showshow sound works. Photo C:I'm not sure what this one shows,but it must be about light or eyesight.
Photo D:Itis a hall of mirrors.Maybe it has to do with the principles of reflection. Photo E:This is probably an experiment involving the composition of light.
(2)Ask students to go through the listening tip and make sure they understand its meaning. Predict by using pictures
One way to get more out of your listening is to predict what you will hear.Using the pictures provided and the knowledge you already have,you can guess the kinds of information you should listen for.At times,you may even be able to guess exactly what will be talked about.This will help you focus better when listening,making your listening more effective.
(3)Tell students that the photos in Activity 1 are related to the conversation they will hear.Ask them to try to predict the answers to the following questions using the photos in Activity 1. (Activity 2)
·Where are the people in the conversation going to go ·What kind of place is it,and what does it focus on
·What kinds of things can you do there
Suggested answers:
·They are going to a science museum.
·It is a science museum that focuses on letting visitors experience science through interactive learning exhibitions.
·You can probably try different activities to learn about sound,light,reflection,and so on.For example,you can go to a room with many mirrors facing each other so it looks like there are many copies of you!Or you can play with a big piano on the floor.
【设计意图】引导学生通过观察图片预测听力内容并回答相关问题，培养他们的听前预测能
力，同时激活学生们的相关背景知识和体验，为接下来的听力理解作准备。
Stepll 应用实践
活动二：获取与梳理 While-listening.
(1)Ask students to listen to the conversation and see if their answers for Activity 2 are correct. Then have them write down the letters (A~E)for the photos in the order that they hear them described.(Activity 3)
Suggested answers:
①D ②C ③E ④B ⑤A
【设计意图】引导学生在听的过程中抓住对话内容的主线，即五个科学体验活动，将活动一 中科学体验活动的照片按描述的顺序排列，培养学生在听的过程中抓取关键信息的能力和对 听力对话的理解和综合分析能力。
(2)Ask students to listen again and complete the descriptionsof the photos in Activity 1.(Activity 4)
Suggested answers:
Photo A:reflects;makes itlouder;whisper Photo B:piano keyboard;classical singers
【设计意图】通过填空，学生再一次对听力对话进行梳理，锻炼在听的过程中抓取对话中的 关键信息和重要细节的能力。
活动三：概括与整合 Post-listening.
(1)Ask students to write a summary of the conversation.
Suggested answer:
Judy had a field trip to a science museum with her classmates last week.First she went to an area for light.In a hall of mirrors Judy saw herself reflected thousands of times.She also experimented with a blue screen and saw her own blood cells moving around like tiny bright lights.The thing Judy liked better was that a white light cast different shadows of Judy in every colour of the rainbow.Later Judy went to the area for sound.Judy played a giant piano keyboard with her feet,and it even produced the voices of classical singers.She also found a giant dish, which reflected thesound back and made it louder so that you could whisper to someone 17 metres away.
【设计意图】通过给听力材料写内容概要，帮助学生回顾听力对话的内容，培养学生提炼信 息的能力。
(2)Ask students to discuss the following questions in groups.(Activity 5)
·The conversation is about the City of Science and Industry,a museum in Paris.Would you like to go to this museum Why or why not
·Are there any museums like this in China What other interesting museums are there
Suggested answers
·Yes.I would like to go to this museum to see the blue screen.I am curious to know what on
earth is going on there and why I can see my blood cells moving around like tiny bright lights.I am sure it will be a lot offun.
No.It is not convenient because it is too far from China and there is no need to go so far when we have so many interesting museums at home.We can't speak French and will have trouble in understanding what to do there.
·Yes.For example,there is the China Science and Technology Museum in Beijing and the Shanghai Science and Technology Museum.
【设计意图】引导学生对听力对话中所描述的科学实践活动发表看法，并结合自己的实际， 与同伴交流分享自己所知道的国内的相关科学体验活动等。
活动四：内化与运用
1.Ask students to work in groups.Have them choose one of the museum activities in the conversation or brainstorm another scientific research or experiment that they are interested in. (Activity 6)
2.Ask students to make a short presentation to the class about their choice.Have them use the example and useful phrasesto help them.(Activity 7)
Suggested answer:
【设计意图】引导学生开展“头脑风暴”,选择一项自己感兴趣的科学研究或实验活动，模仿 教材文本，运用该功能项目的常见语言结构，完成口语任务，并向全班展示和介绍，培养学 生的发散思维和创新能力，也为下面的活动作铺垫。
3.Ask students to summarise how to talk about scientific phenomena. ..can/cannot exist in the form of a solid/gas and a liquid/plasma...
...is both a...and a..at the same time... how light/sound is reflected...
...the existence of other... This occurs when...
If you...,it will become... Thatdemonstrates...
This experiment/research shows...
Through this,we know that... We can prove that..
This evidence proves..
【设计意图】引导学生熟知有关描述科学现象的表达，总结归纳活动能够帮助学生更好地概 括和巩固在谈论自己感兴趣的科学研究或实验活动的情境和其他真实语境中如何运用这些 表达来谈论科学现象。
Step Ⅲ 迁移创新
活动五：批判与评价
Ask students to finish the checklist at the end of the class.
Cheeklist Self Peer Teacher
Can you listen to the conversation and fill in the blanks correctly
Can you write a summary of the conversation
Can you usc what you have learnt to make a presentation about scientific expcriences
【设计意图】引导学生利用本课时的核查清单检测自己对本节课内容的掌握情况，形式有学 生自评、同伴互评和教师评价，实现“教一学一评”一体化。
活动六：想象与创造
Have an English speech contest.
T:Our school is going to hold an English speech contest.The topic is "My interesting scientific experience”.Each player has three minutes.
【设计意图】以班级或年级为单位，进行英语演讲比赛，有利于培养学生的英语表现力，提 高学生学习英语的兴趣，将写和说结合，倡导个性化、体验式教学，提高学生运用语言的能 力。
