Snag Learning offers free access to high quality documentary films from notable producers like National Geographic and NOVA. Snag Learning categorizes documentaries by grade level and content area. Additionally, Snag Learning offers a series of guiding questions for each film. You can embed previews of each video into your blog, but you have to watch the full-length versions on Snag Learning.
