Unit3 Science versus nature
Welcome to the unit
Teaching objectives:
1. To arouse students’ interest in the unit topic
2. To help students kwon more about cloning technology
3. To encourage students to participate in the discussion relevant to cloning
Teaching focus and difficulties:
1. Make sure that students can have the basic knowledge about cloning.
2. Make sure that each student can hold their own opinions towards cloning.
Teaching aids:
The multimedia
Brief teaching proceres:
Step1 Brainstorming
1. Ask students to read the title of the unit Science versus nature. Draw students’ attention to the word ‘versus’. Tell them that ‘versus’ is usually used when discussing sports competitions or the law, which means that two teams or sides are against each other.
Encourage students to think why ‘versus’ is used here. Ask students the following questions:
Do you think there is conflict between science and nature?
What might the conflict be?
2. Show a picture of the first cloned mammal, Dolly. Give some introction about the creation of Dolly. Tell students this new technology is called ‘cloning’, which proces an exact of an animal or a plant from its own cells.
3. Lead students to learn the unit while thinking about the relationship between the title of the unit Science versus nature and cloning technology.
Step2 Sharing information
1. Show the following five pictures one by one, each of which shows a successfully cloned animal. As to the five pictures, we conct the following activities.
(Picture2) Tell students that the mule in the picture is the world’s first cloned mule. It was born on 4 May 2003. His name is Idaho Gem and his brother, Taz, was a racing mule that has won many competitions.
(Picture3) Tell students that the kitten in the picture is called Cc. Its name is from ‘Copycat’. Scientists in the USA created it with a cell taken from its mother, Rainbow. It was born in December 2002.
(Picture4) The five little pigs’ names are Noel, Angel, Star, Joy and Mary.
(Picture5) The pair of calves were born on 5 July 1998 in Ishikawa, Japan. They were two years younger than Dolly, being the second alt animal clones in the world.
(Picture6) The name of the cloned monkey is ANDi. It is from ‘inserted DNA’ spelt backwards. It is the first genetically modified monkey. The technology is different from that used for Dolly.
2. Get students to form groups of four or six to discuss the further questions:
From just these pictures, can you identify the differences between the cloned animals and normal ones?
In your opinion, what might be the differences between these cloned animals and normal ones? Can these animals lead a normal life as normal animals?
Ask several groups to report their answers to the class. Allow different opinions and encourage further discussion.
3. Have students hold a debate about whether it would be a good idea to clone humans some day. Divide students into two groups. One group represents anti-cloning views while the other represents pro-cloning views. Encourage students to provide as many reasons as they can to support their ideas.
Step3 Homework
Assign students to surf the Internet or refer to other sources for further information relevant to cloning technology, so as to finish the first two questions below the pictures. Ask students to make as many notes as possible.
Reading (1)
Teaching objectives:
1.To reinforce students’ comprehension of the text and improve their other skills by participating in all the activities.
2.To help students know the widespread discussion about cloning and hold their own attitudes towards it.
3.To enable students to master the reading strategy and become more competent in reading articles related to science.
Teaching focus and difficulties:
1. Students can work out the meaning of difficult or unfamiliar scientific terms with reading strategy.
2. Students can hold their own opinions on the base of reading the article.
Teaching aids:
The multimedia
Brief teaching proceres:
Step1 Lead- in
Check the homework. Encourage students to share their sources relevant to cloning technology with the whole class. Tell students that cloning has been the subject of scientific experiments for years. The recent success in cloning animals has resulted in fierce debates between scientists, politicians and public.
Step2 Reading strategy
Get students to go through the reading strategy, and make sure that everyone of them understands how to work out the meaning of these scientific terms.
Step1
Begin by reading the first and last paragraphs for an idea of what the article is about.
Step2
Circle any words you do not now. Question things you do not understand or that do not appear to make sense.
Step3
Read through the article a few times, and make sense of the scientific terms upon further readings.

Step3 First reading—Main idea
Ask students to refer to the reading passage and find out the main idea.
(The reading passage is made up of a newspaper article about cloning and two readers’ letters. We will be given information about how cloning is being researched and the different attitudes towards it.)
Step4 Second reading—Understanding scientific terms
Ask students to circle the unfamiliar words or things they do not understand while second reading. (For example: embryo, tissues and organs, interfere with nature, etc)
Step5 Third reading—Detailed information
Ask students to read only the article carefully, and finish the following exercises:
1. What are the different attitudes towards the success of cloning a human embryo?
On the one hand (valuable tissues and organs can be proced and be used to save human lives)
On the other hand (human beings may be on the way to procing a real-life monster)
Some people consider that (cloning human embryos with the intention to destroy them shows no respect for human life.)
2. Who are the persons in the article related to cloning?
persons
introctions
relations to cloning
Ian Wilumt
a Scottish scientist who created Dolly, the first mammal to be cloned successfully from an alt cell
He was shocked when hearing some scientists were considering cloning human beings. He never intends to create copies of humans. Instead, he thinks the efforts of scientists should be directed towards creating new cells and organs that could be used to cure diseases like cancer.
Faye Wilson
a woman of 41 years old who cannot have a baby.
She is desperate to have a baby of her own, a child that is genetically related to her.
Severino Antinori
an Italian doctor, who is one of the leaders in the cloning research
He has declared that he wants to be the first to clone a human being.
Chinese scientists
who have focused their efforts on cloning animals and stem cells to be used in medical research
China has succeeded in procing clones of cows and goats, and continues to research the ways in which cloning can benefit mankind.

Ask students to read the two letters carefully, and judge whether the statements are true or false:
Pauline Carter thinks:
1. the nature will pay back if we interfere with nature. ( T )
2. we should clone fewer babies to rece Earth’s population. ( F )
3. the lady who cannot have a baby can adopt an orphan, but not have a cloned baby. ( T )
Coline Jake thinks:
1. the news that the first human embryo has be cloned successfully is very terrible. ( F )
2. scientists have succeeded in challenging questions of morality. ( F )
3. human cloning is a good way to save her daughter who has died. ( F )
Step6 Further discussion
Understanding the scientific terms and reinforcing the comprehension of the text, students are got to form groups of four or six to discuss the further questions:
1. Find the reasons why people are pro- or anti-cloning in the article and letters and write them in the table below
Pro-cloning
Anti-cloning
1. proce valuable tissues and organs that could be used to save human lives
1. may proce a real-life Frankenshtein’s monster
2. cure disease like cancer
2. create more disease in the animal world
3. help those who are unable to have children
3. cloning shows no respect for human life
4. help those who want to clone their dead children
4. human life would no longer be unique

5. we should be having fewer babies in order to rece Earth’s population, not cloning more

2. Do you think it would be easy for the cloned baby to accept his/ her social identity as a ‘cloned’ human being?
3. What would the person that had the original cell feel about the cloned baby?
4. Think about the relationship between the title of the unit Science versus nature and cloning technology.
Step7 Homework
Think about the difficult scientific terms underlined before up on the text learning
