2. What kind of place is it, and what does it focus on
3. What kinds of things can you do there
1. Where are the people in the conversation going to go
A science museum/centre.
2. What kind of place is it, and what does it focus on
A place for delight, education and inspiration.
Scientific phenomena/discoveries on sound and light.
3. What kinds of things can you do there
Interactive activities to experience/experiment/explore.
Activity 2: Using the photos, try to predict the answers to the following questions.
Activity 2: Using the photos, try to predict the answers to the following questions.
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.
Listen to the conversation to check your prediction in Activity 2.
Take down key words.
1. Where are the people in the conversation going to go
2. What kind of place is it, and what does it focus on
3. What kinds of things can you do there
Activity 3:
Listening and speaking
(1) Listen to the conversation to check your prediction in Activity 2.
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.
(1) Listen to the conversation to check your prediction in Activity 2.
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.
(2) Write down the letters (A-E) for the photos in the order that you hear them.

Listening text:
Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now Better
Bill: Much better, thanks. But how was it
Judy: Wonderful! I especially liked an area of the museum called Light Games. It was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!
Bill: A hall of mirrors can be a lot of fun. What else did they have
Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!
Bill: Come on, tell me!
Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me, in every colour of the rainbow!
Bill: Oh, I wish I had been there. Tell me more!
Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 metres away.
Bill: It all sounds so cool. I wish I could have gone with you.
Judy: I know, but we can go together this weekend. I'd love to go there again!
Bill: That sounds like a great idea!
Activity 5: Talk about something more on the scientific museum.
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
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
Yes.The exhibitions seem really interesting. I think I would learn a lot there.
Are there any museums like this in China What other interesting museums are there
Yes, there is, for example, the China Science and Technology Museum in Beijing and the Shanghai Science and Technology Museum.
Activity 6: (1) Brainstorm a scientific research or experiment (Page 7, Activity 6 & 7).
Example
What scientific phenomenon is the example about
Do you know the phenomenon Where did you know it
What other scientific research/experiments have you ever done or read about
(1) Brainstorm a scientific research or experiment (Page 7, Activity 6 & 7).
1. What scientific phenomenon is the example about
A non-Newtonian fluid.
2. Do you know the phenomenon Where did you know it
Yes. In TV programs or books.
3. What other scientific research/experiments have you ever done or read about
For example: the positive and negative charges of molecules.
n. 分子/微粒
(2) Read the expressions to talk about scientific phenomena (Page 7), using the following expressions
Sample Presentation
Today, I want to talk to you about the positive and negative charges of molecules. We can demonstrate how these interact through a simple experiment using milk, dish soap, and food colouring. First, cover the bottom of a shallow plate with milk. Now add two or three drops of different liquid food colouring to the centre of the milk. They should form one large dark puddle in the middle of the milk. Now, dip a cotton swab into dish soap, and place it into the middle of the food colouring. You will see the colours quickly move to escape from the soap, making interesting and beautiful patterns. This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food colouring with them, making it look like the colours are quickly moving to escape from the soap.
