6、 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!You can also play with a big piano on the floor.Predict by using picturesOne way to get more out o

7、f 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

8、 your listening more effective.What can we predict in these pictures?1.Who?What?Where?When?2.Can we classify them into different types?Picture A&B:sound;Picture C&D&E:light.Located in Paris,France,the City of Science and Industry is the biggest science museum in Europe.The goal of the City is to spr

29、y,I want to talk to you about an interesting phenomenon in our daily life.ProcessTheory图片来源于网络Sometimes,our car windows get foggy.This occurs when there is a difference in air temperature and humidity between the inside of the car and the outside.Phenomenon If you get into the car when it is cold ou

30、tside,your warm body temperature and the moisture coming from your breath will increase the humidity in the car.When this humid and warm air touches the cold glass,the water in the air condenses on the glass to create fog.Though this,we know that water condenses when warm air touches the cold glass.

31、This is how fog is formed on the car windows.3.Think about the function of science:Why do we study science?What can we do with scientific knowledge?Life Bring new inventions.Make peoples lives easier.Mind Inspire curiosity and an attitude of discovery.Increase our understanding of the world.Society
