Today we investigated how lines on a contour map help us make inferences about elevation change. What does it mean when the lines are close together? What does it mean when lines are far apart? Would we rather have a short, steep climb or a long, gradual climb? Where should we start our hike? What will the top of the mountain look like? Can we use contour lines to tell the difference between the shape of Mt. Everest and Mt. Kilimanjaro? After we made a physical model of some contour maps using craft foam, we designed our own mountains with a contour map and built another 3D foam model.
