a giant dish whisper
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.
a piano keyboard play with feet
This looks like a piano a girl is playing with her feet.
Maybe it shows how sound works.
a blue screen bright light
I’m not sure what this one shows, but it must be about light or eyesight.
a hall of mirrors reflect
It is a hall of mirrors. Maybe it has something to do with the principles of reflection.
a white light
cast shadows
in the color of the rainbow
This is probably an experiment involving the composition of light.
The photos above are related to the conversation you will hear. Using the photos, try to predict the answers to the following questions.
1. Where are the people in the conversation going to go?
They are going to a science museum.
2. What kind of place is it, and what does it focus on?
It is a science museum that focuses on letting visitors experience science through interactive learning exhibitions.
3. What kinds of things can you do there?
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.
Listen to the conversation and see if your answers for Activity 2 are correct. Then write down the letters (A-E) for the photos in the order that you hear them described.

Discuss the following questions in groups.
位于巴黎东北部的“科学与工业城”据说是世界上最大、访问人数最多的博物馆之一,同时也是欧洲最大的科普中心。博物馆于1986年对外开放,科学城空间功能分4个部分:永久性陈列(地球宇宙、生命奥秘、物质人类、语言 交流),最新科技成果和工业产品(包括幻影式战斗机和啊丽亚纳火箭和空间站),图书资料中心,底层会议中心。其中还包括3D电影院、水族馆、植物园和众多新科技产品。
What can you do in the City of Science and Industry?
What do you like most about it?
2. Are there any museums like this in China? What other interesting museums are there?
Have you ever been to such a museum in China?
Where is it? What is it like?
What did you do there?
In groups, choose one of the museum activities on the previous page or brainstorm another scientific research or experiment that you are interested in.
Make a short presentation to the class about your choice. Use the example and useful phrases below to help you.
Talking Practice
Let’s talk about scientific phenomena
Today, I want to talk to you about a very strange phenomenon called a non-Newtonian fluid. You can make it easily using equal parts of water and cornflour, like I have here. A non-Newtonian fluid is strange because you can pour it like a liquid, but if you put any pressure on it, it suddenly becomes hard as concrete. In fact, it becomes hard enough to stand on. Then, as soon as you take the pressure off, it becomes a liquid again. This show that it is possible that something can exist as a liquid and a solid at the same time.

Possible Version
Today, I’m going to talk about wind.
In winter, when you open the door suddenly, you will feel the strong sudden wind coming into the room.
How does it happen? Well, there is warm air inside the room. And the warm air is light so it goes up. When we open the door, cold air comes in. And it flows on the surface of the floor because it is heavier than the hot air.
As a result, cool air or cold air takes the place of the warm air. We call this circulation of air wind. All in all, wind occurs when there are temperature differences.

Unit 1 SCIENCE AND SCIENTISTS
Assessing Your Progress
1. Complete the passage with the correct forms of the words below.
The scientist’s main task is to discover how things work in the universe. But few scientists have placed themselves under the __________. So even though the _________ scientific method, which mainly includes hypotheses, data collection, and statistical analysis, is written down, the method by which scientists come to ______ conclusions is hard to identify. Two of the essential qualities a scientist needs to have seem to be curiosity and creativity. People who are curious usually have a mixture of seemingly _____________ desires: They are looking for originality and yet they also want everything in its proper place. To settle the conflict between statistics and _______, scientists often have to be creative, and think outside the box — approach the problem from different directions. They must have a vivid imagination and a strong intuition in order for new _______ to be made. It echoes something the ___________ Carl Sagan once said. He believes that every child “starts out as a scientist” and every child is ______ with the “sense of wonder and awe”.

Science is simply ______ you can do. And doing science makes you a scientist! So, what do scientists do? Actually, what matters is not only _______ they observe in the world around them and what questions they ask, but also ______ they use evidence or data to answer the questions. They identify useful data and take new measurements. Some of the key issues that scientists face are ______ calculations they do and _____ they analyse their data to draw conclusions about the questions they ask. The final issue, which many believe to be the most important, is _____ they need to communicate their results. This is ________ they want everyone to benefit from their work! It seems ________ science is all around us. You see, by doing science, scientists get a better understanding of the world around them and share that understanding with the whole world.

1 Of the explorations in the video, which seems the most important? Which seems the interesting? Why?
2 Why is it important to explore, in your opinion?
3 How would you like to explore our world? Why?
Discuss the following questions in groups.
1 Of the explorations in the video, which seems the most important? Which seems the interesting? Why?
The most important is the one with the butterflies, because butterflies are easily affected by climate and pollution, and so their lives can tell us a lot about how the world is doing.
The most interesting is the cave diving where they found the animal bones. It Just seems so strange and mysterious, and one would not expect to find bones there.
2 Why is it important to explore, in your opinion?
I think it is important to explore because exploration is a part of human growth, both as an individual and society. Through exploration, we develop ourselves. Our interests and curiosity cause us to learn, to improve, and to be better.
3 How would you like to explore our world? Why?
I would like to visit places with my camera and take photos of interesting places and people, as I enjoy photography and love travelling and finding out about new cultures.
Make a short presentation to the class about your scientific experiences.
