Using language
Talk about scientific experiences
Unit 1
Science and scientists
To listen to a conversation about the scientific experience
To extract specific information while listening and complete missing information
To describe the scientific experience in listening
To share the scientific experience you participate in
To make a presentation on a scientific phenomenon
Lead-in
Look at these pictures and predict what are they doing
T: What can you see in Picture A
S1: I can see a boy and a big dish.
T: What’s the boy doing
S1: He’s looking into the dish.
S2: No. I don’t agree. His nose is much closer to the dish, so probably he’s smelling something.
S3: I think he is speaking to the dish.
Lead-in
Look at these pictures and predict what are they doing
T: Why is he doing that
S1: Because the dish can show him some magical scenes.
S2: Because the dish is a machine which can produce
fragrant smells that make people feel good.
S3: Maybe he wants to speak to the people on the other
end of the earth.
T: Good guesses! But did you see the word “whisper” Something amazing is going on there and it is science that makes it happen.
Look at these pictures and predict what are they doing
Lead-in
Picture A: a giant dish, whisper
Picture B: a piano keyboard, play with feet
Picture C: a blue screen, bright lights
Picture D: a hall of mirrors, reflect
Picture E: a white light, cast shadows, in the colour of the rainbow
Look at these pictures and predict what are they doing

Pre-listening
Look at the photos below, and discuss in groups what these activities have to do with science.
Pre-listening
Look at the photos below, and discuss in groups what these activities have to do with science.
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.
This looks like a piano you play with your feet. Maybe it shows how sound works.
Pre-listening
Look at the photos below, and discuss in groups what these activities have to do with science.
I’m not sure what this one shows, but it must be about light or eyesight.
It is a hall of mirrors. Maybe it has to do with the principles of reflection.
This is probably an experiment involving the composition of light.
Pre-listening
Look at the photos below, and discuss in groups what these activities have to do with science.
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.
Pre-listening
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.
While-listening
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.
1. _______________
2. _______________
3. _______________
4. _______________
5. _______________

While-listening
Listen again and write down the key words for each picture.
Picture A: a giant dish, reflect the sound back, speak in a whisper, 17 metres away
Picture B: a giant piano keyboard, use your feet to play, play voices of classical singers
Picture C: a blue screen, tiny bright lights, blood cells
Picture D: a hall of mirrors, see myself reflected thousands of times
Picture E: a white light, cast different shadows, in every colour of the rainbow
While-listening
Listen again and complete the descriptions of the photos above.
Photo A: A giant dish; when you speak into it, it ________ the sound back and ____________________. You can use it to speak in a ___________ to someone 17 metres away.
Photo B: A giant ______________ that you can use your feet to play. Instead of playing the sounds of a piano, it plays the voices of ________________.

While-listening
Listen again and complete the descriptions of the photos above.
Photo C: You look at a blue screen for a while, and then suddenly you can see ________________ moving around on it. These are our ______________.
Photo D: A ______________ where you can see yourself reflected thousands of times.
Photo E: You stand in front of ____________, and it casts different shadows of you, in ______________ the rainbow.
tiny bright lights
own blood cells
