WARMER-FILLER-COOLER Teaching aids

A computer and a projector

Step1. Warmer (8 -10 minutes) Create a free atmosphere to ask the Ss to speak out their opinion about the medical cloning Step 2 Filler 1 (page 15) (4-5 minutes) Read the passage to get more information and try to answer the questions 1.

Why shouldn’t you clone an extinct animal unless there is enough diversity in the group? There will not be enough genetic variation in the group to be able to resist new illnesses.

2.

Why is it wrong to clone an extinct animal if it would have to live in a zoo? It is not a good idea to clone an animal that would have to live in a zoo because it is

not a suitable habitat to develop and increase its numbers. The zoo is not a natural environment for a wild animal.

3.

Why can’t you clone the DNA of animals that have been extinct longer than 10,000 years? The DNA of animal more than 10,000 years old is not suitable for cloning, for it can’t survive so long.

The arguments for medical cloning were very strongly put by the team supporting the motion. They argued that serious illnesses and people who w losing their ability to move or think could be helped by medical cloning. They explained that the procedures would be safe, quick and with no problems for the patients. They quoted that 67% of American citizens are for it to support their idea. Their arguments were very convincing. The arguments put by the team opposing medical cloning were less strong. They argued in two ways. The first reason was that the procedures were not yet secure. Their second reason was that it took many tries and many potential animals had to be killed to produce one useable embryo for research. They explained that man European

countries don’t allow medical cloning research because of this. They quoted Pope John Paul Ⅱ. But their arguments were not so convincing. At the end of the debate the audience we left with a feeling of hope. They realized that diseases that seem terrible today may be able to be cured soon.
