Lesson Plan

Erosion and mountain formation

Show how water erodes mountains to forming streams and depositing sediment in oceans and lakes. Then model how layers up sediment can be uplifted to form mountains.
Science content (2016 curriculum): 
Earth/Space: Water cycle, Water conservation (2)
Earth/Space: Landforms, Erosion (3)
Earth/Space: Rock cycle, Earth Materials, Natural resources (5)
Earth/Space: Fossil records, Geologic time scale (7)

Materials in the activities

Activities in this lesson plan: 

Students experiment with how water shapes the land in the erosion activity.
Discussion includes how sediments are carried downhill by the water and deposited in the "ocean", and then as the layers build, get compressed into sedimentary rock.

As tectonic plates push together, sometimes they both buckle upwards to form mountain ranges.
Sedimentary uplifting activity to show what happens to sedimentary rock layers as they are uplifted.

Discuss cycle of sedimentation, uplifting, erosion.
It happens over millions of years.
