Continuum of Activities

Continuum of Activities

The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.

This continuum of activities offers:

  • Instructional activities designed to be integrated into planned lessons
  • Questions/activities that grow in complexity
  • Opportunities for differentiation for each student’s level of performance

Activities

  1. Define habitat.
  1. Identify one way a habitat can change.
  1. What is a possible effect of trees from an animal’s habitat being knocked down so a city can build a parking lot?
  1. Deer eat grass. Predict what may happen to a deer population as the availability of grass changes.
  1. Beavers build dams that cause water to back up. The water floods the surrounding land. Hypothesize the effects this could have on the ecosystem.
  1. In a prairie, coyotes feed on prairie dogs. Predict what might happen if a new species that feed on prairie dogs was introduced to the ecosystem.

Answer Key/Rubric

  1. Habitat is defined as the place where an animal lives.
  1. Acceptable responses may include, but are not limited to:
  • Examples of change are: if an animal or plant is no longer in the habitat, a change in weather, a natural disaster, human-made changes, etc.
  1. Acceptable responses may include, but are not limited to:
  • Effect: an animal may have lost its home.
  • Effect: more animals might be found in the city due to lack of home.
  • Effect: animals could lose their food source.
  • Effect: species could die out from lack of food and shelter
  1. Acceptable responses may include, but are not limited to:
  • As the amount of available grass increases, the deer population will thrive and increase.
  • As the availability of the grass decreases, the deer population will also decrease, because they depend on the grass for their survival.
  1. Acceptable responses may include, but are not limited to:
  • The beavers will be better suited to survive.
  • The dryland might turn into a wetland ecosystem, so new animals and plants can live there.
  • This could negatively affect the plants and animals that already live there.
  • They might not be able to survive in the changed ecosystem.
  1. Acceptable responses may include, but are not limited to:
  • There might be competition for the prairie dogs between the coyotes and new species.
  • The prairie dog population might decrease/become extinct because a new predator was introduced.
  • The coyote and the new species may not survive if there are not enough prairie dogs.
