60 Second Civics has long been one of my go-to resources for lessons on U.S. civics and government. 60 Second Civics is a daily podcast produced by the Center for Civic Education. Each 60 Second Civics episode offers a short lesson about US Civics. Along with each episode is a one question quiz about that day's episode. As of today there are 3,550 episodes.
You can find 60 Second Civics on the Center for Civic Education's website, on Stitcher, or you can subscribe to it on iTunes.

Playing 60 Second Civics could be a good "starter activity" at the beginning of a US History or Civics class. You might consider combining and or alternating the use of 60 Second Civics with a resource like CNN 10, PBS Newshour Extra, or one of the other news sites I featured here.
