What can you see in the picture? What is he/she doing? Why is he/she doing that? Pre-listening a boy a giant dish The boy is whispering into the smaller circle and the dish can make his voice louder. a giant dish whisper a piano keyboard play with feet Maybe it shows how sound works. a piano keyboard play with feet It is a hall of mirrors. Maybe it has to do with the principles of reflection. a hall of mirrors reflect a blue screen with bright lights The boy is staring at the light,it must be about light or eyesight. a blue screen bright lights a white light; cast shadows in the colour of the rainbow This is probably an experiment involving the composition of light. a white light cast shadows in the colour of the rainbow 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. Activity 2 What can we predict in these pictures? 1. Who? What? Where? When? 2. Can we classify them into different types? Picture A & B: sound; Picture C&D&E: light. 9 Activity 3 Write down the letters (A—E) for the photos in the order that you hear them. 1 ________ 2 ________ 3 ________ 4 ________ 5 ________ D C E B A While-listening Activity 4 Listen again and complete the descriptions of the photos above.

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! Talk and Share: work in group of 4 and brainstorm a scientific experiment or a phenomenon, then share it with us . positive and negative charges of molecules 正负电荷 non-Newtonian fluid 非牛顿流体 Post-listening Today, I want to talk to you about a very strange phenomenon called a non-Newtonian fluid (非牛顿流体). 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(n. 混凝土). In fact, it becomes hard enough to stand on. Then, as soon as you take the pressure off, it becomes a liquid again. This shows that it is possible that something can exist as a liquid and a solid at the same time. Make a short presentation Talk about scientific phenomena Present Scientific phenomena Opening Materials Process Today I want to talk to you about /share with you a scientific experiment named/ called... We need ...; the material we needed is... First, you can ...; Then, you need ...; Now, add ...; You will see ...; This occurs when ... ; If you ..., it will become ...; how light/ sound is reflected ... Theory This experiment/research shows/proves/ demonstrates that ...; We can prove that ...; The evidence proves ...; Through this, we know that ...; ... can/ cannot exist in the form of a solid/gas and a plasma ... Make a short presentation to the class. Use the example and useful phrases below to help you. Show time 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 coloring. First, cover the bottom of a shallow plate with milk. Now add two or three drops of different liquid food colouring to the center 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. Science is endless， it is an eternal mystery. 科学是永无止境的，它是一个永恒之谜。　 Summary Homework Talk about a scientific phenomenon in your daily life. 2.
