　　3) Class work

　　Q1. Is it easy for the scientists to make these inventions and discoveries?

　　Q2. How could they succeed in their research?

　　It is really difficult for the scientists to achieve their goal , and only after tens of thousands of attempts, experiments, thinking and failure can they be successful in their research. Today, we are going to learn one example of them: Franklin’s famous kite eXPeriment.

　　Step 2 Reading

　　1). Individual work

　　Skimming: Read the material fast to find out the right picture about Franklin’s eXPeriment.

　　2). Individual work

　　Scanning: Listen to the tape part by part to find out the topic for each one.

　　Para 1-3 the description of the eXPeriment

　　Para 4 the equipment of the eXPeriment

　　Para 5-6 the steps of the eXPeriment

　　Listen with the questions below:

　　(1). Why did Franklin do this eXPeriment?

　　(2). Was the eXPeriment successful?

　　(3). What were needed when it was being done?

　　(4). How many steps were mentioned?

　　(5). What should be paid great attentions to when it was being done?

　　Step 3 Acting

　　1). Class work

　　With all the equipment ready ( a handkerchief made of silk, two pieces of light wood, strings, a sharp piece of metal, a key, a silk ribbon ), one student acts as the host to conduct two students how to make a kite as the one made by Franklin.

　　2). Individual work

　　After that, all the students try to tell how to make such a kite in their own words with the help of the pictures on the screen.

　　Step4 Further understanding

　　1). Pair work

　　Read through the passage to fill in the blanks in the form in pairs.

　　equipment usage

　　a kite

　　a key

　　a condenser

　　a sharp metal

　　strings

　　a silk ribbon

　　2). Class work

　　Listen to some sentences to judge whether they are true or false.

　　(1). In 1752 scientists already knew what electricity is.

　　(2). Franklin was helped by a friend to do the eXPeriment.

　　(3). Franklin made the kite of silk because wet silk does not conduct electricity.

　　(4). A condenser was used in the eXPeriment to store electricity.

　　(5). The key tied to the string was put into the door to stop the kite from flying away.

　　(6). The eXPeriment can be done at any time.

　　(7). You can feel clear electric shock if you touch the string with your fingers after the kite is flying in the sky.

　　Step 5 Post-reading

　　1). Pair work

　　Franklin was doing the experiment with his little son, and he was a bit curious about what his father was doing. On the other hand, many people were watching Franklin doing the experiment. Divide the class into two groups to make a dialogue in pairs, one is between Franklin and his son ,the other Franklin and a person watching the eXPeriment.

　　2). Group work

　　Discuss the following questions in groups:

　　(1). Why did Franklin
