Focus Concept:
The propagation and importance of kelp to the marine community

Sub-concepts:
Anatomy of kelp; Interactions between kelp and marine species; Effect on habitat of otters preying on sea urchins and sea urchins feeding on kelp; Biodiversity of kelp forests; Propagation of kelp forests in Glacier Bay; Botany: plant or protist; The effectiveness of a marine preserve for protecting species, such as giant kelp; Special adaptations to a marine environment

Generalization:
Kelp forests promote marine biodiversity. In the absence of predators such as the sea otter, kelp forests can be decimated by grazers such as sea urchins. With the return of the sea otter to Glacier Bay, the kelp forests have returned. A wide variety of living creatures could not survive in the urchin barrens but thrive in the kelp forests.

Guiding Question:
What is kelp and why is it important to biodiversity in Glacier Bay?

 

Critical Content
Students will know ...

  1. The anatomy of kelp

Skill Objectives
Students will be able to ...

  1. Compare a protist and a plant using classroom models.
  2. Use Venn Diagrams to determine if a organism is a protist or a plant.
  3. Compare temperate rainforests to kelp forests.
  4. Create a mural to compare the biodiversity of a kelp forest to that of a temperate rainforest.
  5. Use comparisons to prove the importance of kelp forests to the planet.
