Geography Elements/Standard(s) Emphasized:
* Standard 7: The physical processes that shape the patterns of earth's surface
* Standard 15: How physical systems affect human systems
* Standard 17: How to apply geography to interpret the past
Time: The basic part of the lesson including the activity would take
one class period, however, this lesson has been designed to be integrated
into a thematic unit that could be a day or a week.
Materials/Equipment: world atlases, large (at least 12"x22" plastic
container, clear or white plastic sheet (at least 3x3), newspaper, water,
food coloring (optional), watering can or spray bottle, water-soluble colored
markers, Stream Drawing (master handout), white paper and drawing materials
Objectives/Goals:
* identify and illustrate parts of a stream
* describe how and why a stream develops
* design your own stream
Suggested procedure for teaching the lesson:
Introduce unit by reading A River Ran Wild by Lynne Cherry.
Use the Cause and Effect skill worksheet.
Do a vocabulary web.
Identify the six parts of a stream.
Open the lesson. Individually or in groups, have students locate the
Nile, the Amazon, and the Colorado rivers in their atlases. Identify their
common features: Their sources are in the mountains; they flow overland
for a great distance; and they eventually flow into an ocean, sea, or
gulf. Locate and describe their sources. Remind students that all streams
flow from higher to lower elevations under the influence of gravity. Review
the six parts of a stream.
Demonstration: Explain that students will experiment with water to demonstrate
*the force of gravity on water
*the way some rivers begin
*how all rivers flow from high to low points
Conclude the lesson. Have students draw and label the six parts of
a stream. Include features of the surrounding landscape, such as mountains,
hills, valleys; a lake, gulf, or ocean at the mouth; and people along
the banks using and enjoying the water. Students may want to tape their
drawings together to create a longer course for their river.
Extending the lesson: River Research
* Find out how great civilizations of the past depended on rivers for their
growth such as the Chinese and the Egyptians.
* Explore which cities, towns, and industries have been established in proximity
to rivers.
* Find out how the presence or absence of a river has affected your community.
* Other research topics-Erie Canal, Pittsburgh, trading on the Mississippi,
textile manufacturing, and the Grand Canyon Field Experience
As a class or as individuals, study a nearby river or stream. Visit it frequently
to note changes throughout the school year. How will the water flow affect
the bands and course of the stream? Use journals, photographs and drawings.
Compare and analyze throughout the year. Study the effects of floods
* Research the Mississippi River flood of 1993. Have students research one
aspect of this disaster and report to class.
* Role play: Have students debate whether or not people should move back into
an area that floods regularly. Have one group take the role of home owners,
and the other take the role of government leaders who want to keep people
from building homes too close to some rivers. Literature Links
