Ecology

   By the End of Grade 3
Students know and are able to:

3.3.12 explain that habitats provide basic  needs, (i.e., food, water, shelter, energy) for the organisms living in them.

NatureWorks Episodes

5. Habitat
6. Marine Communities
7. Fresh Water Communities
8. Terrestrial Communities
   By the End of Grade 5

Students know and are able to do everything required at earlier grades and:

3.5.12 cite evidence that individuals and groups of organisms interact with each other  and their environment  (i.e., food chain, reproduction, decomposition).
