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.
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.
Make a short presentation to the class about your choice. Use the example and useful phrases below to help you.
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. Anon-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 shows that it is possible that something can exist as a liquid and a solid at the same time.
