Some of you may already know about this resource, but I just learned about it today! WatchKnowLearn has indexed over 20,000 educational videos in over 3,000 categories. The videos are available without any registration or fees to teachers in the classroom adn to students at home 24/7. WatchKnowLearn believes everyone should have the same opportunity to learn. They will even accept suggestions for videos to be added to their directory. The videos on their site are guaranteed kid safe! WatchKnowLearn is a non-profit program and was the idea of the Community Foundation of Northwest Mississippi and a Memphis-area philanthropist. Dr. Larry Sanger, a co-founder of Wikipedia, was tapped to help plan the educational video service.
Very quickly I was able to find some videos on Ferdinand Magellan, using the History > History of Exploration > Magellan, Ferdinand path. The first video listed was a cute song about Magellan's journey performed by the Animaniacs. The second was a beautiful video with music and images, plus different facts about Magellan. It was so quick to find something I could use if I was teaching about the exploration period of human history.
I also noticed you can filter by age, so that would help if you were looking specifically for primary school or high school videos. There are even some informational videos which adults would find helpful - such as "Using an Asterisk in Google Search" which explains how the * is used in a Google search as a placeholder.
