Determining whether the information we encounter in the world is accurate has always been a
problem. In the age of the internet we have unprecedented access to information, but the struggle
to determine if it is credible may only have gotten worse. Here are a few resources (some videos,
some text-based guides) for grappling with this issue. View or read at least two of these (your
choice) to help inform your work in the rest of this activity.

SIFT (The Four Moves)
Evaluating news stories about science:
1. When reading an article, webpage, blog post, etc. about a scientific topic, list three
features that might make you question the credibility and/or the accuracy of the
information. For each feature, briefly explain why it should make you doubt the
credibility of the information.
Examining news about climate change:
2. By searching online, find a recent (less than six months old) news article about climate
a. Summarize the article in 3-5 sentences. Try to present the article accurately,

Compare & Contrast Climate Change Information
Peruse the material associated with global warming on these two sites:
A. Climate Depot (https://www.climatedepot.com/)
B. Climate Change: Facts (https://climate.nasa.gov/evidence/).
For each of these sites, look for some portion of the website that makes specific claims about
climate change. (You don’t need to find matching topics from the two sites.)
3. Using criteria discussed in the background resources, describe two features of website A
that you think make it credible or dubious. Explain each feature and how it applies in a
few sentences each.
4. Repeat question #3 for website B.
