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 do his experiment with a kite? (2). Why the kite made of silk is better than the one made of paper? (3). Is it dangerous for Franklin to do the experiment? Why do think so? (4). What can you lea
