1、Unit 1 Science and ScientistsPeriod 4 Using langauge （1） Listening教学设计The theme of the listening section is talk about scientific experiences, which focuses on visiting the science museum, Through this way of scientific inquiry and experience, students can activate their relevant experience, talk ab

2、out different types of scientific inquiry activities, describe their experience of participating in scientific experiments and scientific research, and communicate with their classmates. This section reflects the connection between science and life, science and learning.Text analysis: listening text

3、 is a dialogue between friends. In the dialogue, Bill was not able to visit the science museum because he was ill. His friend Judy told him about the interesting experience of scientific exploration. This experience involves many scientific fields such as physics and biology, and fully mobilizes vis

4、itors multiple senses such as vision, hearing and touch. Judy gave a vivid description of the experimental facilities in the museum, and also expressed her own wonder and curiosity.Instruct students to predict the listening content by observing the pictures and to develop their pre listening predict

7、inLook at the photo below, and discuss in groups what these activities have to do with science.keys:A: 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.B: This looks like a piano you play with your fee

8、t. Maybe it shows how sound works.C: Im not sure what this one shows, but it must be about light or eyesight.D: It is a hall of mirrors. Maybe it has to do with the principles of reflection.E: This is probably an experiment involving the composition of light.Step1: Before listening:The photos above

9、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?2. What kind of place is it, and what does it focus on?3 .What kinds of things can you do there?keys:1 Where are the people i

10、n 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

11、 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.Step2: Ask students to listen to the conversation and see if th

Then write down the letters (A-E) for the photos in the order that students hear them described.keys: DCEBAStep 3: .Ask students to listen again and complete the descriptions of the photos abovePhoto A: A giant dish; when you speak into it, it _ the sound back

Instead of playing the sounds of a piano, it plays the voices of_.Photo C: You look at a blue screen for a while, and then suddenly you can see_ moving around on it. These are our_Ph

The convers

15、ation is about the City of Science and Industry, a museum in Paris. Would you like to go to this museum? Why or why not?Yes . I can learn a lot about science and it can broaden my horizons.2. Are there any museums like this in China? What other interesting museums are there?Yes. There are other inte

16、resting museums such as art museum or museum about science and technology. Step 5: Instruct students to make a short presentation to the class about your choice. Use the example and useful phrases below to help them.EXAMPLEToday, I want to talk to you about a very strange phenomenon called a non-New

17、tonian 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

18、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.useful phrases:useful phrases:Talking about scientific phenomena. can/cannot exist in the form of a solid/gas and a liquid/plasma .

21、dence proves keys: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 differe

22、nt 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 middle of the food place coloring. You will see the colors quickly move to escape from the soap, making interesting and beautifu

23、l 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 coloring with them, making it look

24、like the colors are quickly moving to escape from the soap.Listening text:Judy: 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! I especially liked an area of the museum called L

25、ight 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. Youll 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
