Learning Procedures
Step 1 Warming up
Today, we are going to talk something about the subjects you are learning.
Q1: How many subjects are you learning now?
Q2: What are the subjects in which you learn science? Is it easy for you to learn them?
1). Group work
Divide the whole class into two groups, one group is going to talk about the question “ What do you learn about for each field of science?”, and the other “How are you learning these subjects?” Write down the result of the discussion in a card, and choose the best member to do the report.
2). Class work
Enjoy some pictures about the facilities in labs and students doing experiments in labs.
Q: Which subjects are connected with these pictures? Do you often do experiments in the lab?
Step2 Pre-listening
1).Group work
Is it necessary for you to do experiments in the lab? List the reasons in the card and see which group can find more.
2).Class work
Do you still remember what your teacher often remind you before, when and after you do an experiment? Divide the whole into several groups to have a competition in class and see which group will win the game.
Step 3 Listening
1). Listen to what Mr. Zhu is talking to his students for the first time, focusing on the subjects mentioned in the passage.
2). Listen to the tape for the second time to write down some key words to the questions and check with the partners.
3). Listen to the tape for the third time. Understand the whole passage fully and check if the answers are complete, especially pay attention to different structures of giving instructions.

Step 4 Post-listening
1). Group work
List what you can do and can’t do in a lab as much as possible in groups.
2). Individual work
Knowing the rules in a lab is very necessary for the sake of our safety. Suppose you are a chemistry teacher, and you are going to make an announcement to your students to give them some instructions before an experiment.
3). Group work
Design the rules for the chemistry lab of your school in groups and put it on the wall in the classroom.
Homework:
Task 1. Have a discussion to find out the best rules for the lab and recommend it to the school leader.
Task 2. Preview Speaking and try to search for some information about the new inventions and discoveries.
Period 2 Speaking

2). Pair work
Make a dialogue in pair to talk about one of the inventions, using the structures to show your agreement and disagreement, such as I’m afraid…/ I can’t agree with you./ I don’t think so. / In my opinion… And then act it out.
Step 4 Post-speaking
1). Debate
The scientific technologies are improving very fast. Some of them are widely accepted and applied, while some are still being argued about by people. Cloning humans is still one of them. In your opinion, do you think it good to do so all over the world?
Divide the whole class into two groups to have a debate and see which group will perform better.
2). Imagination
If you were a scientist many years later after you graduated from universities. Do you think what you would try to invent or discover? And why do you think so?
Homework:

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 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 learn from the experiment and also Franklin?
Step 6 Oral practice
1). Individual work
After you read the interesting experiment of Franklin, do you think of one of your own experiments? Is it a very successful one? And what do you learn after you do the experiment? Tell the story to your group members, and then choose the best one to share it with the whole class.
2). Class work
During the lifetime of many famous scientists, there are a lot of interesting and instructive stories for us to enjoy. Then, we are going to hold a story telling competition in class.
Have some judges among the students first, and then each group choose one student to present the story in front of the classroom. See who can get the first prize in the competition.
Step 7 Watching, reading and thinking
1). Class work
The teacher is ding such an experiment and showing it to all the students: Prepare four glasses on the table. One is filled with oil, one vinegar, and one spirit. Pour some of the liquid into one big glass and then mix them up. Dip one finger into the mixture, take it out then and put it into the mouth to suck. Then give a smile to the students to show that it tastes very delicious. Show the glass around the class and ask the students to do everything as the teacher does.
Q: Does the mixture taste good? Why do you have a different taste from mine?
2). Individual work
Read the passage titled “Look carefully and Learn” to find out the reason.
Q 1: What do you learn after you read such a story?
Q 2: Do you think what is the most important when you are doing an experiment in the lab?
Q 3: If you want to be a scientist, what do you think are the most important qualities?
Homework:
Read the following passage with the questions below.
Flossie Wong-Staal
An interview with Emilio Alvarez and Ann Crystal Angeles
Flossie Wong-staal stays on the move. She moved with her family from China to Hong Kong when she was five. Later she moved to the United States to attend college. Now Wong-Staal is on the move to clone the virus that is believed to cause AIDS and to figure out how the molecules（分子）of the virus are arranged. Wang-Staal heads a team of scientists at the university of California, San Diego. They are trying to save lives by making an AIDS vaccine(疫苗).
Emilio: How did you decide that you wanted to become scientist?
Wong-Staal: At first my teachers made the decision. In high school they said I should study science because of my grades. By the time I graduated from college, there were so many exciting discoveries being made in molecular biology that I wanted to specialize it.
Emilio: What was your high school like?
Wong-Staal: I went to an all-girl high school in Hong Kong. I felt very free at an all-girl school, and I have fond memories of that time.
Anne Crystal: Would you explain your research?
Wong- Staal: Basically me colleagues and I are trying to understand how the AIDS virus is replicated, and then to develop ways to interrupt the replication process, By “replication” I mean the way in which the virus gets inside a cell and uses that cell as a sort of factory to make many many copies of itself.
Anne Crystal: Do you always enjoy your job in the laboratory?
Wong-Staal: Yes,, I think it’s very exciting work. Of course it’s not every day that you make a discovery and have that kind of reward. But when it does happen, it’s a real thrill. It’s exciting to know that you brought about knowledge that didn’t exist before.
Anne Crystal: What would you tell students who would like to become research scientists?
Wong- Staal: Stay with your interest, and get good information about the education you will need. I also have warning: Things are not always easy. There are frustrations in research; sometimes things don’t go the way you’d hoped. But when you make a discovery or a contribution to science, it becomes worthwhile. And I want to encourage all young people to be interested in science: We need you !
1. As you read, guess the meaning of the boldface words from the surroundings words and sentences.
1. Look back over the reading to find the following information:
(1). Where Wong-Staal was born: (2). What she is studying in her research:
(3). What she was the first person to do:
(4). This article is primarily about______________.
A. the scientist Wong- Staal B. making an AIDS vaccine
C. preventing the spread of disease
(5). Which question is NOT answered in the reading?
A.What college did Wong- Staal attend
.B.What type of biology did she specialize in
C.Where does she work now
(6). You can infer that Wong- Staal
A. didn’t want to become a scientist
B. is happy she becomes a research scientist
C. plans to retire soon
2. Write about the following two questions in your journal.
(1). Wong- Staal says that there are frustrations in research. What do you think she means? What frustrations might there be in doing research? How would you deal with these frustrations?
(2). Wong- Staal says that here teachers decided she should become a scientist. Do you think teachers should make career choices for their students? Why or why not?
Period 5 Language study
Learning Aims
Enable students to have a better knowledge of the rules of word-formation.
Learning Procedures
Step 1 Warming up
Daily report: Show your opinions about the two problems mentioned in the reading passage.
Individual work
Show a tongue twister to students:
If one doctor doctors another doctor, does the doctor who doctors the doctor doctor the doctor the way the doctor he is doctoring? Or does he doctor the doctor the way the doctor who doctors doctors?
Practice the tongue twister for some times and see who can say it correctly and fast.
Q: Do all “doctors” in this sentence have the same meaning?
Conclusion: The meaning of the same word varies in different sentences and so does the gender.
Step 2 Reading and thinking
1). Pair work
Read the following sentences to distinguish the different meanings of the same word.
How much do you charge for repairing my CD player?
The frightened animal charged into the toy shop.
It usually takes one hour to get my call phone fully charged.
The man was charged for being irresponsible for the job in the court.
We gave her the charge of the house when we were away for holiday.
What is the charge for using the hall?
The guide conducted the tourists around the museum.
How well does this material conduct electricity or heat?
The concert on this Saturday evening will be conducted by a world famous conductor.
The teacher scolded him because of his bad conduct.
The manager conducted the business carefully.
He was surprise to see so many crosses marked in his Maths homework.
This fruit is a cross between an apple an d appear.
The river was too deep to cross.
The two main roads cross in the center of the town.
He crossed his name off the list.
2). Group work
Discuss in groups to think about more words of this kind and make sentences according to the different meanings. Then read it out and the other students try to guess the meaning of the same word in different situations.
Step 3 Imagination
Group work
Show some words on the screen ( such as bank, tie, sharp, tear) . Discuss in groups to make a short story, paying great attention to the different meanings and gender of the same word. Write it down on a card and share it with the whole class. See which group does the best job.
Step 4 Compound words
Sometimes if we put two different words together, we can make a new one. These words are called “Compound words”. Show some examples:
Blackboard is compounded with two words:
Part 1= a kind of deep color Part 2= a piece of thin wood
Show the students the formulation: Part 1 + Part 2 = ?
1). Class work
The teacher provide explanations to two single words. Ask the students to combine them together and then guess what the new word is. Repeat it for several groups.
Part 1= part of the body used when we talk Part 2= a round thing to play with
Part 1= water of ten degrees below zero Part 2= medicine to put on your skin
Part 1= a liquid you need to make tea
Part 2= moving in snow with wooden thing tied to your shoes
2). Group work
Discuss to think of some some compound words in groups and then do the same game with the partners.
3). Class work
Have a competition about word guessing and see which team can give the most wonderful performance.
Two students to make a team with one facing the blackboard and the other facing all the students. The teacher lists some compound words on the screen. The students facing the Bb explains the two parts of the compound word as quickly and exactly as possible, so that the other one can join the two parts together to guess which word is mentioned. The game is limited in two minutes and then they can find out which teams have guessed more words than the others.
Step 5 Post-learning
Read the story about “Franklin’s famous kite experiment” again , and try to find out all the similar words as those learned in this class.
Homework:
Task 1. Design an exercise to match the words in Column A with those in Column B to make some compound words. Exchange the exercises in class.
Task 2. Prepare to make up a story about the relationship of humans and animals in groups and then act the short play out.
