Science denial, misinformation, and science con-artists are on the rise. We are plagued by anti-vaxxers, climate change naysayers, and promoters of ineffective fad diets and medical cures. The scientifically literate citizen or consumer needs skills in differentiating good science and trustworthy sources from impostors. Here, I present a series of student-centered activities that help students inquire into the nature of credibility and the problems of expertise, mediated knowledge, and science communication. I open with a playful guessing game about “fantastic beasts” reported in the 16th century, then follow with more modern examples. I then describe a science version of “To Tell the Truth,” a reflective exercise on “Finding the Expert,” and then a student opportunity to explore deceptive strategies by trying to bluff their classmates with false news stories about science. These all develop basic concepts in science media literacy and prepare students for more serious investigation into a contemporary scientific controversy.
