7、light.It is a science museum that focuses on letting visitors experience science through interactive learning exhibitions.Pre-listening3.What kinds of things can you do there?Interactive activities to experience/experiment/explore.You can probably try different activities to learn about sound,light,
8、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.Activity 2:Using the photos,try to predict the answers to the following questions.Pre-listeningActivity 2:Using the ph
9、otos,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
10、 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(2)Write down the letters(A-E)for the photos in the order that you hear them.1 _ 2 _ 3 _ 4 _ 5 _ABCDEActivity 3：(1)Listen to the conversation to c

20、ctivity 6:Talk about something more on the scientific museum(Page 7,Activity 5).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?2.Are there any museums like this in China?What other interesting museums are there?Yes,th
21、ere are,for example,the China Science and Technology Museum in Beijing and the Shanghai Science and Technology Museum.Yes.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 see my blood cells moving around like tiny bright ligh
22、ts.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 there.Post-listeningphenomenon n.现象 (pl.phenomena)Let
23、s talk about scientific phenomenaToday,I want to talk to you about a very strange phenomenon called a non-Newtonian liquid.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 pressu
24、re 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 show that it is possible that something can exist as a liquid and a solid at the same time.Definition/TermExampleExplanationConclusionPost
25、-listening:Sample Study(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 e
26、ver done or read about?For example:the positive and negative charges of molecules.n.分子分子/微粒微粒Activity 7:Talk about the scientific research or experiment that you are interested in.Post-listening:talk about scientific phenomena(2)Read the expressions to talk about scientific phenomena(Page 7).EXAMPLE

28、ment 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 coloring 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 it into the
29、 middle of the food place coloring.You will see the colors 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 a
30、ttracted to each other,and so they appear to move around on the plate,taking the food coloring with them,making it look like the colors are quickly moving to escape from the soap.Post-listening:talk about scientific phenomena Homework1.Make a short presentation about the scientific research or experiment.2.Use the example and useful expressions in Activity 7 on page 7 to help you.Thank You for your attention！
