9、and what does it focus on?3.What kinds of things can you do there?They are going to a science museum.It is a science museum that focuses on letting visitors experience science through interactive learning exhibitions.You can probably try different activities to learn about sound,light,reflection,and
10、 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.While listeningP6 3.Listen to the conversation and see if your answers for Activity 2 are correct.Then write down the letters(A-E)fo

16、all 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 b

18、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

20、ion to the class about your choice.Use the example and useful phrases below to help you.EXAMPLEToday,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 bec
21、ause 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

23、evidence proves Talking about scientific phenomenaToday,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
24、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 middle of the food place coloring.You will see the colors quickly move to escape from the soap,making inter
25、esting 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 coloring with them,making it look like the colors are quickly moving to escape from the soap.Homework1.Preview the passage on page 7.2.Recite the words in Unit 1.Bye-bye!
