Students watch a video about the Snake River. They learn about river formation and the power of water. Students label a map of the Snake River and define the different parts of a river.
This lesson is part of "Great States: Idaho Unit 2: Geography" in which students will come to understand that the physical environment is not static. Through geological processes and human action, seemingly fixed aspects of the landscape are constantly changing and have always been doing so. As the earth influences how people live, how people live in turn effects the earth.
Standards: 4.SS.2.1.1 Use geographic skills to collect, analyze, interpret, and communicate data.
- Video: Rivers | Science Trek
- A smart board, projector, or other screen to show videos to the class
- Class set of Snake River Map handout
- Image: The Tetons and the Snake River
Tell students they will be watching a video about the Snake River. Instruct them to pay close attention to the terms the video explains, such as a meander or oxbow.
Play the video, Rivers | Science Trek [3:40].
Ask students: where does the water that feeds a river come from?
Distribute the Snake River Map handout and have students follow its instructions.
Project the image, The Tetons and the Snake River by Ansel Adams.
Based on the information in the video, ask students to define the terms: inner bank, outer bank, and a meander. Then ask, “can anyone in the class point to these spots on the river image?”
- Creeks and streams, underground springs, snowfall and rain
Inner – where sediments are deposited by water
Outer – where water erodes and washes away the land
Meander – the curve of a waterway
On the closer curve, the inner is the east and outer bank is the west. Meander is the turn.
