4. Perception depends on: age gender social class home location educational background

5. Nature of Science Scientific Method observation – question(s) – hypothesis testing – experiment results – statistical analysis conclusions

6. Testing Hypothesis manipulative and natural experiments – manipulative experiments paleontology: too old/few to experiment cosmology: too large/far away to experiment – natural experiments experiments can be conducted naturally without manipulation Ecology is a mixture of both types of experiments

7. Scientific process scientific method peer review conference presentations grants & funding for the study repetitions Theory is produced paradigm: the theory can shift with time

8. Sustainability population + consumption = environmental impact What do you think of the footprints of different societies? Do countries with bigger footprints have an obligation to reduce it? Do third world countries, have the obligation to retain the low footprint they already have before developing economically and industrially?
