Do you know the meaning of the word “experiment”? It means “trial made in order to prove

7、the truth of an idea”. For example, I hope to find the answer to this problem by experiment. Do you often do experiment? S5: Yes. We often do experiment in physics, chemistry and biology in the labs or in the classroom.T: So today we are going to learn an experiment.Step2: Pre-readingWork in pairs,

8、and discuss why an iron knife and nail rust.( the students may say its because of water and oxygen.) How can you prove that? (to conduct an experiment). Introduce some key new wordsdissolve electricity equipment oxygen react rust solid steam test tube.Step 3: ReadingLeading-inWe know the experiment

9、you did just now tell us a truth that metal may react with different substances in a certain situation. Now, were going to learn something about an experiment. Skim the text to get a general understanding Fast reading: Read Passage A and choose the best title for it.A.The Different Uses of MetalsB.T

( Key: Potassium )2)What happens when you heat calcium in oxygen? ( Key: It will burn to form

11、an oxide )3)Which metals react with steam?( Key: Magnesium, Alumminium and Zinc )4)Does iron have a slow or fast reaction with steam? ( Key: It reacts slowly.)5)Does copper react with water? ( Key: No )Read passage B and fill in the table.(on page 44) Compare the 5 sentences and find the different u

13、ing rusted, it is not good. How can you solve this problem?Step 5: DiscussionDo you think it is easy or difficult for you to carry out a scientific experiment well? And can you describe how to do it successfully in simple words?If you want to learn science subjects well, what qualities do you think

14、you should have? (Possible answer: We should be careful / serious / diligent / patient / thoughtful /etc.)Step 6: Reading practice Read the following passage within 5 minutes and make a proper choice to each problem. During the 19th century scientists found that when certain parts of the brain of a

15、man were injured, he would lose the power to do something. And so people thought that each part of the brain did a different job. But modern research has found out that this is not so, for it is not easy to say exactly what each part of the brain does. In the past fifty years, there has been a great

16、 increase in the amount of research done on the brain. Chemists and biologists have discovered that the way the brain works is not so simple as people in general may think. Chemists tell us that 1,000,000 chemical changes take place in the brain every second. Some recent researches also suggest that

17、 we can remember everything that happens to us. We may not be able to recall the things weve heard and seen, but it is all kept there in the storehouse of the mind. Earlier scientists thought that the power of ones brain got weaker and weaker as one grew older. But it is now thought that it is not t
