1、Using Language Unit 1 Science and Scientists Have you ever been to any science museums?Share your experience.Warming-upLook at the photos below,and discuss in groups what these activities have to do with science.Pre-listeningI think the dish in this exhibition is related to sound.Maybe the boy is wh
2、ispering 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.Im 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.T
3、his 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.ABCDEPredict by using picturesOne way to get more out of your listening is to predict what you will h
4、ear.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.2.What kind of
5、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.Where are the people in the conversation going to go?They are going to a science museum.3.What kinds of things can you do there?You can probably
6、 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
7、 are correct.Then write down the letters(AE)for the photos in the order that you hear them described.1._ 2._ 3._4._ 5._?While-listeningJudy:Oh,Im so sorry that you were ill and couldnt come with us on our field trip.How are you feeling now?Better?Bill:Much better,thanks.But how was it?Judy:Wonderful

25、a great idea!Listening text 1.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?Post-listeningYes.I would like to go to this museum to see the blue screen.I am curious to know what on earth is going on there and why I can
26、see my blood cells moving around like tiny bright lights.I am sure it will be a lot of fun.No.It is not convenient because it is too far from China and there is no need to go so far when we have so many interesting places at home.We cant speak French and will have trouble in understanding what to do
27、 there.2.Are there any museums like this in China?What other interesting museums are there?Yes,there are,for example,the China Science and Technology Museum in Beijing and the Shanghai Science and Technology Museum.3.Make a short presentation about scientific research or experiment that you are inte

30、f 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.Name Process Theory&Significance Sample WritingMaterials
