I love Animoto (and have blogged about them in the past here and here). It’s an incredibly easy way to create a sophisticated video from still pictures. While you can create 30 second videos with a basic account, they also offer accounts for educators which allow you unlimited access.
It’s very simple to use. Just upload your pictures to the site, add text (if you want), and pick your music (they have a lot to choose from). Then Animoto does of the work for you by putting your music and pictures together in a professional looking way! Here’s a quick animoto of some of the younger grades at East Salem using technology.
