I enjoy playing Discovery Education videos for my students, but don't enjoy when they try to nap or shut down.
My solution to them 'not paying attention' was to preview and make a test, question set, that follows along with video clips.
This question set goes along with the Discovery Education video entitled: Landforms Number One. All of the various landforms (examples: desert, plateau, plain, canyon, etc.) are discussed throughout while taking a vitual trip around the world.
