Well if you were an engineer you would take part in the experiment of making Shen Zhou Flight What kind of materials would you like to use S1 I d like to use some materials that are light enough and hard enough so that the flight can be easily sent up into space and doesn t get in trouble T How can we find such kind of materials S2 We can do some experiments We can t use natural materials only we need both man made and natural materials T That s right Now we ll read a passage about a scientific experiment Please turn to page 44 We ll go through Passage A When we are doing a thing we should do it in an orderly way It s especially true with a scientific experiment Now let s see the four words in the table conclusion aim result and method The four words are about the orders or stages of a scientific experiment We must know these two words result and method What are the meanings of the other two words S3 Aim should be about what the experiment is for For conclusion I have no idea T Right Aim means purpose or object For example he has only one aim in life that is to be a millionaire And for conclusion let s see an example first when you have worked on a maths problem for a long time but you 9 still can t work it out So you may make a conclusion that the problem is wrong Here the problem is wrong is your conclusion Do you understand Ss Yeah T Now who can give us some other examples to show the meaning of aim S4 Many people aim to be a millionaire But I think to serve people is the highest aim T What is the correct order of stages to do an experiment Ss It should be aim
