The Smithsonian Channel features fabulous FREE content, including full episodes and lots of video clips. Learn about eating bugs, the making of the Monkees and the space shuttle Discovery. The amount of content is amazing!
I love educational videos like this, but won't let my kids watch even good videos on YouTube due to the unpredictable nature of the related videos that show up on the side. I feel great about letting my kids explore and learn with this app! It's currently featured in iTunes as a New & Noteworthy app. And it's FREE!
