A project of the Annenberg Public Policy Center at the University of Pennsylvania, this nonpartisan, nonprofit organization states that it "aims to reduce the level of deception and confusion in U.S. politics." The entries here cover TV ads, debates, speeches, interviews, and news releases. Science teachers take note: The site includes a feature called "SciCheck," focusing on false and misleading scientific claims used for political influence. Beyond individual entries, there also are articles and videos that teachers might find helpful.

SciCheck

FactCheck.org’s SciCheck feature focuses exclusively on false and misleading scientific claims that are made by partisans to influence public policy. It was launched in January 2015 with a grant from the Stanton Foundation. The foundation was founded by the late Frank Stanton, president of CBS for 25 years, from 1946 to 1971.

From the independent Tampa Bay Times, this site tracks who's telling the truth -- and who isn't -- in American politics. Updated daily, the site's entries fact-check statements made by elected officials, candidates, and pundits. Entries are rated on a scale ranging from "True" to "Pants on Fire" and include links to relevant sources to support each rating. Overall, the site's content is written for adult readers, and students may need teachers' help with context and direction.

This popular online resource is all about internet rumors. Fact-checked entries include everything from so-called urban legends all the way to politics and news stories. Teachers should know: There's a lot here, covering a variety of topics -- some of it potentially iffy for younger kids. It's a great resource for older students -- if you can keep them from getting distracted.
