This is an in class activity to demonstrate to students typical features associated with streams in different topographic settings from headwaters to the mouth of the stream.
This activity is used in an introductory earth science course for non-majors.
Skills and concepts that students must have mastered
Students need a basic knowledge of erosional and depositional processes in fluvial environment and a basic understanding of river systems.
How the activity is situated in the course
This is a stand-alone exercise to help students understand fluvial systems.
Content/concepts goals for this activity
The concept goals of this exercise are (1) help students to connect fluvial landforms with the topographic setting in which they occur and (2) helpt ehm to understand the forces affecting fluvial systems.

Description of the activity/assignment
The exercise is a virtual fly through of a river system from its headwaters in the mountains to its mouth at the ocean. As a classroom activity we travel (via satellite images) through a stream system and observe the changes in gradient, stream channel pattern, discharge, and depositional and erosional features. Students are able to observe the topographic settings in which various fluvial systems form.
