In the time following the 2016 presidential election, much has been written about the spread of false information on social media websites. Given the potential influence false information has had on American politics, it is more important than ever for people to critically evaluate the content they view and share on social media.

In the activity, students are asked to generate an internet meme related to U.S. politics and write a short essay defending the position they have taken in the meme.
