2. Students can research different dinosaurs and find out about what's known about their lifestyle (food they ate, how they defended themselves from predators, etc) and the evidence or theory of how they became extinct.
3. Students can research the various current uses of genetic engineering and their impact on our society. They can learn how bio-engineering of plants works as well as cloning of animals and how this technology can be adapted to humans. If a species has been dead, is it possible to re-introduce it back into our society? Can we re-create dead humans from the past and will they act the same as they did in the past or will they be affected by the changes in our society over time?
