Teaching procedures:
Step 1 Pre-reading (3 minutes)
Today we come to the reading. It's about Franklin's kite experiment. As we all know, Benjamin Franklin is a famous politician. But today we will read a passage about him as a scientist. We should learn about his serious attitude towards science. Let's see how Franklin made his famous electricity experiment by flying a kite.
The teacher can ask students some questions, such as the following:
Do you have the experiences of flying a kite?
Have you ever made a kite by yourself?
Why do you often go out to fly kites?
Then students share their own ideas with each other.
(Justification: This step can activate students' background knowledge, and also can help the teacher introduce the theme of the text.)
Step 2 While-reading (14 minutes)
(1) Fast reading
The teacher can ask the students to read the passage quickly and match the paragraphs with the main ideas (on the screen).
Show the following on the screen:
Paragraph 1
The Tip of doing the experiment
Paragraphs 2-3
Introduction to Franklin's experiment
Paragraphs 4-6
The process of the experiment
Students browse the text quickly to get the general idea.
(Justification:This activity can train students' ability of skimming for the main idea.)
(2) Careful reading
①The teacher will ask students to read the text carefully to find relevant information:
A. List all the materials that are needed to make a kite.
B. List what are needed to do the same kite experiment as Franklin did.
C. Get students to read the text and then decide whether the following statements are true (T) or false (F).
a. In 1752, scientists already knew what electricity is. ( )
b. Franklin was helped by a friend to do the experiment. ( )
c. Franklin made the kite of silk because wet silk does not conduct electricity. ( )
d. A condenser was used in the experiment to store electricity. ( )
e. The key tied to the string was put into the door to stop the kite from flying away. ( )
Students finish the reading task and report to the whole class.
(Justification: This activity could train students' ability of scanning for detailed information.)
② Use the multimedia to present Franklin's experiment.
Students are asked to fill out the form about Science Report.

(Justification: This activity can help students know how to write a science report.)
Step 3 Post-reading (8 minutes)
Present some questions:
①Why is the kite made of silk better than the one made of paper?
②Do you think Franklin's experiment was dangerous? And why?
③What do you learn from this experiment?
Students are asked to think about the questions, discuss with classmates and report to the whole class.
(Justification:These questions can help students understand the text better and offer them opportunities to communicate with their classmates.)
