Think&Share
1.How do you understand the statement “...we should not always believe everything we read or hear-even if it is a great story”
I think the statement is right. From a scientific standpoint, people should stick to the facts and the facts should be proved by experiments and research. A good story is fiction which is often more interesting than the truth.
2.What qualities do you think a great scientist should have
As a great scientist, he or she should have more than one good quality, such as being smart, honest, objective, persistent, curious, imaginative etc.
Group work
Work in groups.Explain your understanding of the saying “Seeing is believing”, and then give a talk about it.
Your understanding of the saying Supporting details
As the old Chinese saying goes,“What you hear about may be false, but what you see is true.” We often easily believe what we see or hear with doubt,but as a matter of fact, it is not always so convincing. New research suggests that the story of Franklin’s experiment may be fiction instead of fact.
Some scientists questions the story about apple that fell on Newton’s head and led him to come up with his theory of gravity. In fact, there is no proof that the apple hit him on the head.
Personally, we can not be content with what we see or hear. As the old saying goes, “Practice is the sole criterion for testing truth.” What we see or hear is true or false remains to be seen in the future. Please don't hesitate to taste what you see or hear.
Summary
Summarize what we have learnt today.
Homework
1. Review new words and phrases learn in this period.
2. Polish your report of the experiment.
