Camp Bible Wahoo! a "church camp themed" Sunday School program that can be used as a VBS, or summer program, or anytime you want to create a special set of classroom spaces. Similar to the Rotation Model, it was designed to use readily-available materials to create special indoor learning spaces for teaching Bible stories. You might change the "theme" depending on your chosen stories.
The camp theme can work for just about any Bible story.
Lake Bible Wahoo! had a real sand floor!
The inspiration came from an old "seaside with the Savior" curriculum.
