My 4th grade students participated in making several stop motion videos with me.  For some reason, the video clips look great in After Effects but turn to a blurry mess when I upload them to YouTube. I'm not sure which setting I'm missing.  The stop motion below was made using biography bottles that were made to go with a biography project this year.  The kids helped with the background and did all of the movement in the photos.  I edited out several arms but missed a few fingers in some shots.  
The last two bio-bottles are Bill Gates and Steve Jobs.  A little humor...Steve Jobs bowls Bill Gates over with an apple.  
I would love to learn more about stop motion in the future.
