Salt Creek Watershed Project

Activity Outline

The following is a list of the research activities that each grade level will be doing. By no means does this mean that 9th grade students have to do the soil chemistry or the 11th grade students have to do the water quality. At Waverly High School, freshman (9th) take Earth Science, sophomores (10th) take Biology, and Juniors (11th) take Chemistry. This is the best fit for us. Keep in mind that this is an interdisciplinary unit. The list below only represents the scientific research component. The Social Studies, English, and Math components will be represented in the Activities and Lesson Plans Link.

Student Activities by grade:

9th Grade

  • Soils chemistry (pH, Chloride, Nitrogen, Alkalinity, Phosphorus, etc.)
  • Flow rate of stream (pre- and post-channelization)
  • Soil composition identification (silt, sand, and clay)
  • Analyze CASDE infrared imagery based on soil composition
  • Topography mapping of Salt Creek Watershed.
  • Analyze their results of Salt Creek.

10th Grade

  • Analyze biodiversity of plants (pre- and post-channelization)
  • Analyze biodiversity of animals (pre- and post-channelization)
  • Analyze biodiversity of fish (pre- and post-channelization)
  • Analyze surface water results (Dissolved Oxygen, pH, etc.) from Junior class and relate to fish populations.
  • Analyze their results of Salt Creek.

11th Grade

  • Groundwater chemistry (Nitrates, Nitrites, Chlorides, Alkalinity, pH, Phosphorus, Iron, Dissolved Solids, etc.)
  • Surface water chemistry (Dissolved Oxygen, Nitrates, Chlorides, Alkalinity, pH, Dissolved Solids, etc.)
  • Analyze their results of Salt Creek.
  • Analyze results of all test (9-11) to make a summation of Salt Creek Watershed.

The study will be conducted at 6 sites along Salt Creek. 2 sites will be west and south Lincoln or in the pre-channelized portion of the Creek. 2 sites will be in Lincoln and the last 2 sites will be located north of Waverly and southeast of Ashland. The last 4 sites are in the channelized portion. Ashland is the area where Salt Creek dumps into the Platte River and ends the Salt Creek Watershed. The sites will be visited twice. This will give the students a snap-shot look at the effects of urbanization and channelization of stream as it flows through a major city and becomes channelized.
