I use this overview digestive system assignment to get the students seeing the overlaps of our intricate body system. Instead of just drawing the digestive system on to a poster board, they are to use several layers of paper to show how "opening" a flap/layer would reveal more structures.
Initially, the students would struggle with the complexity of the assignment, but once they get going, and understand what it means to "open a flap/window", they love working on this project! Check out the previews.
