Strand V
Use Scientific Knowledge from the Earth and Space Sciences in Real-World Contexts

 

Science/Strand V
Content Standard 2
All students will describe the characteristics of water and demonstrate where water is found on Earth; describe how water moves; and analyze the interaction of human activities with the hydrosphere. (Hydrosphere)

High School

 

Science/Strand V/Content Standard 2/High School
Benchmark 1
Identify and describe regional watersheds.

Benchmark Clarification

Maps are commonly used to plan water management, evaluate potential disposal sites, and analyze pollution events that concern both surface and ground water. Watersheds include many political jurisdictions such as counties, municipalities, and townships, which makes management difficult.

Students will:

  • Outline local and regional drainage basins/watersheds on maps
  • Mark drainage divides on maps

Instructional Example

Benchmark Question: What are the characteristics of the watershed in which you live?

Focus Question: On a map of your county, what are the major watershed(s)?

The teacher will provide each student with a map of their county. The class will identify the surface streams (rivers, creeks, etc.), lakes, and ponds.

Students will:

  • Draw arrows on each stream indicating the direction of the flow of streams, lakes, and ponds
  • Draw drainage divides (lines where water on either side of the divide line flows in different directions)
  • Name watershed(s) according to the largest stream that flows out of the county
  • Compare and contrast (using information from the internet) their watershed map with watersheds identified by the USGS database

Suggestion: Consider using Michigan county maps outside your district.

Constructing: (SCI.I.1.HS.4).

Reflecting: (SCI.II.1.HS.1).

 

Science/Strand V/Content Standard 2/High School/Benchmark 1
Assessment Example

Provided with a map of your county emphasizing the surface streams (rivers, creeks, etc.), lakes, and ponds, each student will complete the four tasks listed below:

  1. Draw arrows on each stream indicating the direction of flow of streams, lakes, and ponds
  2. Draw drainage divides (lines where water on either side of the divide line flows in different directions, to different watersheds)
  3. Name watersheds according to the largest stream that flows out of the county
  4. From the internet, compare/contrast your watershed map with watersheds identified by the USGS database

Note: A stream is a general name for all rivers, creeks, runs, tributaries, etc. A tributary is a stream that flows into another stream.

(Give students rubric before activity.)

Scoring Rubric

Note: Because the map will be specific to the region, the total number of streams, drainage divides, and watersheds will vary. Therefore, specific numbers could not be indicated on the rubric but could be added at any time by a teacher to allow for adaptation to a specific area or region.
