1. Collect three science or medicine stories reported on the internet by different news sites and then fact-check them. How well did the facts that they reported hold up? Identify which sources you used to establish the trustworthiness of the reporting. (Hint: If you’re having troubling knowing where to start, read Fact checking: How to think like a journalist and Fake news: How not to fall for it.
2. Go to the internet and download three versions of the same story from different news outlets. Choose one produced by a newspaper, one by a TV-news outlet and a third by another news outlet. How do they compare in the detail they provide? How do they compare in the certainty they offer about the findings? How many sources have they cited to establish facts or skepticism of the reported findings? Which did you find most believable? Which was least believable or least satisfying? Explain your assessments.
