Coastal Habitats & Species—Salmon Studies

Summary: Through water quality monitoring, assess habitat suitability for salmon.

Concepts to teach: Adaptations, survival, migration, freshwater vs. saltwater habitats

Goals: Students will learn about the unique life cycle and migration habits of salmon and how they find their way back to their freshwater breeding grounds.

Standards:
H.2L.2, H.3S.1, H.3S.2, H.3S.3

Specific Objectives:

  1. Describe the importance of watersheds to salmon life cycles.
  2. Define the term “anadromous”
  3. For three measurable indicators of watershed health, determine the parameters within which salmon may survive and thrive.
  4. Collect and analyze water quality data to determine the degree to which a body of water is suitable for salmon.

  • The Oregon Watershed Enhancement Board (OWEB) website provides background information on how Watershed Assessments are conducted and used.
  • The 550-page Stream Scene curriculum is available in .pdf format on the ODFW website, and covers a variety of watershed topics.
    • The chapter Aquatic Organisms contains several classroom lessons having to do with salmon habitat, including:
      • Riffles and Pools, p. 357—“Students will apply concepts learned about habitat needs of salmonids during their life cycle by completing a work sheet analyzing riffles and pools.”
      • Home Wet Home, p. 393—“Students will recognize the habitat components necessary for salmonids in a stream, and analyze and describe how each stream structure contributes to salmonid habitat needs.”
    • See the chapter Field Investigations for protocols of complimentary outdoor investigations.
  • Salmon dissection resources available in the Elementary level Salmon Studies topic guide
  • Visit the Oregon Hatchery Research Center or a hatchery closer to your school
    • Do the self-guided OHRC Quest, which is a clue-directed interpretive hunt created by 8th graders at Crestview Heights School in Waldport
    • Make your own Quest or other interpretive guide that helps the public learn about salmon and salmon habitat

Assessment:

  • Post sampling data on StreamWebs and seek out similar data collected by others.
  • Determine whether your study site is suitable for salmon, and use data to explain why or why not.
