Contour Lines and Topographical Maps

We've spent the last two days working outside (what a great two days of weather too) learning about contour lines.  Contour lines are lines on a topographical map that connect points of the same elevation.  Using a simple hand level and a six-foot rod that has been measured into one foot increments, students developed ways to create a contour line based on a specific elevation.
