教学过程
Step I 学习理解
活动一：感知与注意
Get t knw abut the City f Science and Industry
Lk at the phts belw，and discuss in grups what these activities have t d with science
Suggested answers：
A I think the dish in this exhibitin is related t sund. Maybe the by is whispering int the smaller circle and the dish can make his vice luder.
B This lks like a pian yu play with yur feet.
Maybe it shws hw sund wrks.
C I’m nt sure what this ne shws, but it must be abut light r eyesight.
D It is a hall f mirrrs. Maybe it has t d with the principles f reflectin.
E This is prbably an experiment invlving the cmpsitin light.
【设计意图】在听力之前，讨论与听力材料有关的科学探究活动，有助于激活学生的已有背景知识。
活动二：策略学习
Predicting by using pictures
1.策略介绍
G thrug th the sentences and make sure students understand their meanings.
Predict by using pictures
One way t get mre ut f yur listening is t predict what yu will hear. Using the pictures prvided and the knwledge yu already have yu can guess the kinds f infrmatin yu shuld listen fr. At times, yu may even be able t guess exactly what will be talked abut. This help yu fcus better when listening, making yur listening mre effective.
2.策略运用
The phts in Activity 1 n Page 6 are related t the cnversatin yu will hear. Using the phts，try t predict the answers t the fllwing questins.
·Where are the peple in the cnversatin ging t g?
·What kind f place is it, and what des it fcus n?
·What kinds f things can yu d there?
Suggested answers：
·They are ging t a science museum.
·It is a science museum that fcuses n letting visitrs experience science thrugh interactive learning exhibitins.
·Yu can prbably try different activities t learn abut sund, light, reflectin, and s n. Fr example, yu can g t a rm with many mirrrs facing each ther s it lks like there are many cpies f yu! Or yu can play with a big pian n the flr.
【设计意图】在学习听力策略之后，设计与听力策略有关的三个问题，让学生在听力实践中应用策略解决听力的问题，有助于提高学生的学习能力和效率。
活动三：获取与梳理
1.Listen and match
Listen t the cnversatin and see if yur answers fr Activity 2 are crrect. Then write dwn the letters（A-E）fr the phts in the rder that yu hear them described.
Suggested answers：
1D 2C 3E 4B 5A
2. Listen and fill
Listen again and cmplete the descriptins f the phts abve.
Suggested answers:
A reflects; makes it luder; whisper
B pian keybard; classical singers
C tiny bright lights; wn bld cells
D hall f mirrrs
E a white light; every clur f
【设计意图】播放两次录音，第一次听验证预测是否正确并给五张图片排序；第二次听获取五张图片的细节内容。通过这个活动，学生学习和运用预测学习策略，获取和整合五张图片的细节内容，更重要的是获取科学实验的相关经验，有助于加深对单元主题意义的理解，也有利于口语活动的开展。
Step Ⅱ 应用实践
活动四：分析与判断
Discuss the fllwing questins in grups.
·The cnversatin is abut the City f Science and Industry，a museum in Paris. Wuld yu like t g t this museum？Why r why nt？
·Are there any museums like this in China？What ther interesting museums are there？
Suggested answers:
·Yes. The exhibitins seem really interesting. I think I wuld learn a lt there.
·Yes. Fr example, there is the China Science and Technlgy Museum in Beijing and the Shanghai Science and Technlgy Museum.
【设计意图】在获取巴黎科学工业城的相关信息后，学生表达自己是否愿意去参观巴黎科学工业城，并阐述其原因。接着展开想象，国内是否有类似的博物馆。这个过程有利于实现语言知识的内化，提高学生的语言表达能力，深化对主题的认识。
活动五：描述与阐释
Talk abut anther scientific research r experiment
1.Learn language.
（1）Ask students t read the fllwing structures.
(2) Ask students t read the abve structures ver and ver again until they can speak fluently
2. Chse a tpic.
In grups, chse ne f the museum activities n Page 6 r brainstrm anther scientific research r experiment that they are interested in.
3. Make a shrt presentatin
(1) Read the example.
（2）Make a shrt presentatin t the class abut yur chice. Use the example and useful phrases abve t help yu.
【设计意图】在口语输出之前，教师给学生提供一些描述科学研究或实验活动的过渡句型。学生通过阅读，获取这些信息，为口语活动提供背景常识和语言结构，使得有话可说。
Step Ⅲ 迁移创新
活动六：想象与创造
Write abut yur wn scientific research r experiences
1.Ask students t write abut their wn interesting Scientific research r experiences.
2.Share their writings in grups.
【设计意图】在英语课堂教学中，设定特定的场景，让学生结合自己的经验去描述和阐述自己的科学实验和科学经历，使学生们在轻松愉快的环境中学习，激发出学生主动学习的愿望，发展学生的语言运用能力，培养学生对科学的兴趣。
板书设计
Pht A: A giant dish; when yu speak int it, it ________ the sund back and ________. Yu can use it t speak in a ________ t smene 17 metres away.
Pht B: A giant ________ that yu can use yur feet t play. Instead f playing the sunds f a pian it plays the vices f ________.
Pht C: Yu lk at a blue screen fr a while, and then suddenly yu can see ________ mving arund n it. These are ur ________.
Pht D: A ________ where yu can see yurself reflected thusands f times
Pht E: Yu stand in frnt f ________, and it casts different shadws f yu, in ________ the rainbw.
Talking abut scientific phenmena

…is bth a… and a... at the same time…

…the existence f ther…
This ccurs when…

That demnstrates…
This experiment/research shws…
Thrugh this, we knw that…
We can prve that…
This evidence prves…
Example
Tday, I want t talk t yu abut a very strange phenmenn called a nn-Newtnian fluid. Yu can make it easily using equal parts f water and crnflur, like I have here. A nn-Newtnian fluid is strange because yu can pur it like a liquid, but if yu put any pressure n it suddenly becmes hard as cncrete. In fact, it becmes hard enugh t stand n. Then, as sn as yu take the pressure ff, it becmes a liquid again. This shws that it is pssible that smething can exist as a liquid and a slid at the same time.
