Essential Question:
How do rivers change as they flow across Earth’s surface?
Overview
In this lesson, students learn about key physical features and human activity that affect river systems as they flow across the surface of Earth. Students examine photographs of important features along the Nile River that show how the river changes in its journey from source to mouth. They use longitude and latitude coordinates to plot the features on a map of the Nile and annotate the map to explain how those features reflect changes in the river.
Objectives
Students will
Geoterms
Students will define and explain the importance of these key geographic terms: hydroelectric potential, perennial irrigation, river basin, water cycle, cataracts, confluence, runoff, reservoir, delta, infiltration.

Objectives
Students will
- understand key physical features and human activity that affect river systems by identifying how the Nile changes from source to mouth.
- examine how hydroelectric dams impact river systems around the world.
