So here is a good project to try with the kids. Have them do both an open and closed composition of the same subject matter and display the 2 together. For the closed composition you can just set up the still life but for the open you may have to get them to view it through a old mat or frame. You can also add a photography component. Get them to photograph an open composition and then paint the view.
