I saw this project at a teacher's workshop that I attended. My Sister-in-Law and nieces teach these workshops. You can see more ideas I saw here: http://kidsbibledebjackson.blogspot.com/2012/08/bible-teachers-workshop.html
We also made this Mt. Sinai foam visual. Click on the picture above to see the directions.
