Understand how karst topography is created. Learn the geographic vocabulary that is used to explain karst development. You could also have students read the articles on the Ozark Highlands and ask them to explain karst topography. Divide students into groups of three or four. Give each group a box of sugar cubes, a tube of caulking and a pie plate.
Students are to construct a rectangle by gluing the cubes together with the caulking.
The box of cubes should be 6 X 10 X 5 cubes. Suggest students use just enough caulk to make the cubes stick together. Layers of cubes should not be water proof. Cover the outside of the completed sugar mountain on all sides, including the bottom. It is better if each sugar mountain is different, so don t worry about making each one the same.
