The Contour Model Kit by United Scientific teaches how contour lines represent elevation. Students fill an 11¼" x 6" x 3½" PET container holding a polystyrene landform model with water in stages and trace each waterline onto clear PET sheets to create a topographic map. Includes 5 tracing sheets, a wax pencil, a 6-inch ruler and an activity guide for groups of up to 5 in geography and earth science classes.
