Lesson Plan

  • Teacher will model and teach how to make quiet observation at “Benjamin” or “Turtle” and then, in a separate trip observe interactions (60-90 mins).
  • Teacher will provide examples of Spokane and other cultural models of abiotic/biotic relationships.
  • Teacher will explore how a peoples’ culture is shaped by their environment. Ceremonies revolved around salmon; with the dams in place, Spokane’s no longer practice.
  • Teacher will have the students create a project that represents our objective using a menu of different types of models they can select from using different mediums (e.g. picture, videos, songs, clay, models, powerpoint.)


  • Each day – exit ticket. Written reasoning for creation of their project.
  • Day 1: ID biomes for tomorrow.
  • Day 2: Provide a list of organisms (don’t forget plants ☺).
  • Day 3: Select how you are going to represent your model.
  • Day 4: List of materials needed for model.


Have student write their own “coyote” story about their project. The story must reflect a lesson for different interpretations – DO NOT state the moral/lesson.
