Oklahoma Science Standards

   Grades K-3

Plants and animals need to take in air, water, and food. In addition, plants need light.

NatureWorks Episodes

5. Habitat
9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/Scavengers

Plants and animals have features (e.g., breathing structures, limbs, skin covering, seed dispersal,  roots, stems, and leaves) that  help them live in environments such as air, water, or land.

NatureWorks Episodes

1. Adaptation
2. Coloration
5. Habitat
6. Marine Communities
7. Fresh Water Communities
8. Terrestrial Communities
14. Niche

Each plant or animal has different structures that serve different functions in growth and  survival (e.g., the way it moves, type of food it needs, and where it lives).

NatureWorks Episodes

1. Adaptation
2. Coloration
5. Habitat
6. Marine Communities
7. Fresh Water Communities
8. Terrestrial Communities
14. Niche

All animals depend on plants. Some animals eat plants for food. Other animals eat animals  that eat the plants.

NatureWorks Episodes

9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/Scavengers

Hibernation, migration, and camouflage are ways organisms increase their survival.

NatureWorks Episodes

1. Adaptation
2. Coloration
4. Migration

Plant and animal materials decay and are reused in the environment

NatureWorks Episodes

11. Decomposers/Scavengers

   
   Grades 4-5

Plants and animals have different structures that enable them to function in their environment (e.g., feathers for flight or cactus  needles for water conservation and protection).

NatureWorks Episodes

1. Adaptation

Living organisms can be classified using various characteristics (e.g., habitats, anatomy, behaviors, and other features).

NatureWorks Episodes

6. Marine Communities
7. Fresh Water Communities
8. Terrestrial Communities
13. Species Diversity
14. Niche
15. Invasive Species

Some source of energy is needed for all organisms to stay alive and grow. Energy transfer can be followed in food chains and webs.

NatureWorks Episodes

.9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/ Scavengers

Changes in environmental conditions can affect the survival of individual organisms and/or entire species.

NatureWorks Episodes

4. Migration
5. Habitat
12. Population Dynamics
16. Life at Risk

Organisms in a community depend on each other for food, shelter, and reproduction.

NatureWorks Episodes

6. Marine Communities
7. Fresh Water Communities
8. Terrestrial Communities
9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/Scavengers
14. Niche

Human interactions, such as building, pollution, and clearing the land impact the environment.

NatureWorks Episodes

4. Migration
5. Habitat
12. Population Dynamics
16. Life at Risk
   Grades 6-8

Individual organisms with certain traits are more likely than others to survive and  produce offspring.

NatureWorks Episodes

1. Adaptation
2. Coloration
3. Natural Communication
4. Migration

Sunlight is the ultimate source of energy.

NatureWorks Episodes

9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/Scavengers

Population growth and decline are dependent n various factors.

NatureWorks Episodes

12. Population Dynamics

In all environments, organisms  with similar needs may compete with one another for resources,  including food, space, water, air, and shelter. Other relationships may be beneficial.

NatureWorks Episodes

9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/Scavengers
12. Population Dynamics
14. Niche
15. Invasive Species

Organisms within an ecosystem are dependent on one another and on nonliving components of the environment.

NatureWorks Episodes

9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers/Scavengers
14. Niche

By classifying organisms, biologists consider details of internal and external structure.

NatureWorks Episodes

13. Species Diversity

Organisms have a great variety of internal and external structures that enable them to survive.

NatureWorks Episodes

1. Adaptation
2. Coloration
3. Natural Communication
4. Migration
