The representative from team 1 will pick up a piece of the paper e.g. scientist - he/she has to talk about GM food assuming the role of a scientist. The representative from team 2 pick up a piece of the paper e.g. local farmer - he/she has to talk about GM food assuming the role of a farmer. Points will be awarded according to the accuracy of the points presented and that it must be relevant to the role they assumed.
Love this idea and would like to share with all of you. As the student assume the different role, they would see GM food in different perspective - both positive and negative. e.g in the show, the "scientist" mentioned how GM food would solve the world food shortage problem and the "local farmer" express concern over the high cost of GM seeds and the competition from farmers who produce GM food crops.
This would also test them to think on their feet as well as to know the content well enough to assume the role they have drawn.
