Diversity of LifeBy the end of the 5th grade, students should know that A great variety of kinds of living things can be sorted into groups in many ways using various features to decide which things belong to which group. Features used for grouping depend on the purpose of the grouping. NatureWorks Episodes6. Marine Communities7. Fresh Water Communities 8. Terrestrial Communities 9. The Wildlife Web I 10. The Wildlife Web II 11. Decomposers and Scavengers 13. Species Diversity 14. Niche 15. Invasive Species 16. Life at Risk By the end of Grade Eight students should know that NatureWorks Episodes9. The Wildlife Web I10. The Wildlife Web II 11. Decomposers and Scavengers 13. Species Diversity Animals and plants have a great variety of body plans and internal structures that contribute to their being able to make or find food and reproduce. NatureWorks Episodes1. Adaptation2. Coloration 3. Natural Communication 4. Migration 5. Habitat 6. Marine Communities 7. Fresh Water Communities 8. Terrestrial Communities 9. The Wildlife Web I 10. The Wildlife Web II 11. Decomposers and Scavengers All Animal Focus Sections For sexually reproducing organisms, a species comprises all organisms that can mate with one another to produce fertile offspring. NatureWorks Episodes13. Species DiversityAll organisms, including the human species, are part of and depend on two main interconnected global food webs. One includes microscopic ocean plants, the animals that feed on them, and finally the animals that feed on those animals. The other web includes land plants, the animals that feed on them, and so forth. The cycles continue indefinitely because organisms decompose after death to return food material to the environment.

Interdependence of LifeBy the end of the 5th grade, students should know that: For any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all. NatureWorks Episodes5. Habitat6. Marine Communities 7. Fresh Water Communities 8. Terrestrial Communities 15. Invasive Species 16. Life at Risk Insects and various other organisms depend on dead plant and animal material for food. NatureWorks Episodes11. Decomposers and ScavengersOrganisms interact with one another in various ways besides providing food. Many plants depend on animals for carrying their pollen to other plants or for dispersing their seeds. NatureWorks Episodes9. The Wildlife Web I14. Niche Changes in an organism's habitat are sometimes beneficial to it and sometimes harmful. NatureWorks Episodes5. Habitat14. Niche 16. Life at Risk Most microorganisms do not cause disease, and many are beneficial. NatureWorks Episodes11. Decomposers and Scavengers
