Lesson plan

Mountain landforms and their erosion

Build models of mountains from a contour map, then use sand and water to explore how water erodes mountain sides.
Science content
Earth/Space: Landforms, Erosion (3)

Build mountains using a contour map, to understand how their shapes are represented on maps.
Discuss how mountain shapes are changed by water flow and erosion.

Watch erosion in action with a demo of the sand and water erosion activity (or student groups can each have their own, but this adds quite a bit of time to the lesson).

Erosion by water, as well as ice and wind, slowly over thousands of years, changes the landscape. Maps need to change to reflect that.
