Another video, STEM, created on a black dry erase board with neon markers.  We used this as an introduction to a video about our STEM academy.
 
Links to some stop motion videos my students and I created.
Nileometer  This was interesting, we tried to green screen a stop motion - forgetting the green "riverbank" would disappear, along with a lot of the yellow and white!  We used an editable video from Discovery for the background.
Here is a link to the stop motion base file.

Friends  Students created this video with no narration needed - it uses foam letters.

Respiratory System  Created using WikkiSticx and a black line master.  Although narration was added later in iMovie, this version is before the addition.  It is very short, it was copied several times into iMovie to make it long enough to fit the narration.
