This paper outlines a design study conducted in an after-school program setting with middle-school aged children in an urban district in the North Eastern United States in order to: 1) design a microworld for Density in order to deepen students' content knowledge of Density, 2) design a set of content knowledge items to assess and characterize students' prior knowledge with regard to density, 3) characterize their inquiry skills before using the microworld, and 4) characterize their inquiry processes via their log files generated as they work within the microworld.
