In looking at C-SPAN Classroom's collection of state history resources it appears that the clips and bell ringers cover a wide array of topics related to each state. For example, the collection of Maine resources includes a video of top policy issues according to former governor Paul LePage, the Missouri Compromise, and the removal of a dam on the Kennebec River. The collection of resources about Iowa includes a bell ringer about the history of the Iowa caucuses, a bell ringer about African American migration to Iowa, and a lesson plan about the Louisiana Purchase.
