Diversity
1. Many different kinds of plants and animals live throughout the world and can be classified or sorted into groups based upon appearance and behavior.

Interactions Within the World Around Us
1. The Earth consists of living and non-living things. All living things interact with each other and the non-living parts of their surroundings - air, water, soil, and sun.

NatureWorks Episodes

5. Habitat
6. Marine Communities
7. Fresh Water Communities
8. Terrestrial Communities

2. Living things depend on each other in many ways. Animals use plants for shelter, and eat plants and other animals for food. Plants depend on animals to carry their pollen and to disperse their seeds.

Structure/Function Relationship
1. Living things have structures that function to help them reproduce, grow, and survive in different kinds of places.

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

Flow of Matter and Energy
1. All living organisms interact with the living and non-living parts of their surroundings to meet their needs for survival. These interactions lead to a constant exchange of matter and energy. Plants derive energy from the sun for growth and survival. Animals eat plants or other animals that have also eaten plants to satisfy energy needs. When plants and animals die, they are eaten by decomposers.

10. The Wildlife  Web II
11. Decomposers and Scavengers

Regulation and Behavior
1. Living organisms are composed of parts that work together to ensure the survival of the whole organism. The behavior of an organism is influenced by internal clues such as hunger and external clues such as air temperature.

NatureWorks Episodes

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

Diversity
1. Organisms have many distinct and unique features which they use for survival. Specialized features include those for finding food, building shelters, evading predators, and reproducing. Scientists use similarities and differences in these features to classify and group organisms.

NatureWorks Episodes

1. Adaptation
2. Coloration
3. Natural Communication
4. Migration
13. Species Diversity

Evolution
1. Organisms of the same species have variations which may provide an advantage in reproduction and survival.

Interactions Within the Environment
1. All living organisms interact with the living and non-living parts of their surroundings to meet their needs for survival. These interactions lead to a constant exchange of matter and energy. Plants derive energy from the sun for growth and survival. Animals eat plants or other animals that have also eaten plants to satisfy energy needs. Dead plants and animals are eaten by decomposers.

Changes in Environment
1. Organisms adapt in order to live and reproduce in certain environments. Those organisms that are best suited for a particular environment have adaptations that allow them to compete for available resources and cope with the physical conditions of their immediate surroundings.

NatureWorks Episodes

1. Adaptation
2. Coloration
3. Natural Communication
4. Migration
16. Life at Risk

2. Changes in an organism's environment can either be beneficial or harmful. Organisms may be affected by other organisms, by various physical factors (e.g., rainfall, temperature), by physical forces (e.g., storms, earthquakes), and by daily, seasonal, and annual cycles.

NatureWorks Episodes

15. Invasive Species
16. Life at Risk

3. Pollution and human activities can change the environment and adversely affect the health and survival of humans and other species. Careful planning and safe practices are required in waste disposal, recycling and waste management, pest control, and use of resources to ensure the well being of humans and the environment.

   Grades 6-8

Matter and Energy Transformations
1. Plants make their food by the process of photosynthesis. Using light energy, green plants convert water and carbon dioxide into energy-rich simple sugars and oxygen. Sugar is the source of food used by most plants, and ultimately, by all other consumers. Oxygen produced during photosynthesis is required for the survival of most plants and animals.

NatureWorks Episodes

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

2. All living things obtain energy from food. Energy is needed for living cells to carry out all the processes of life such as growing, disposing of wastes, making new cells, and using food.

10. The Wildlife  Web II
11. Decomposers and Scavengers

Evolution
1. Natural selection is the process by which some individuals with certain traits are more likely to survive and produce greater numbers of offspring than other organisms of the same species. Conditions in the environment can affect which individuals survive in order to reproduce and pass their traits on to future generations. Small differences between parents and offspring accumulate over many generations and ultimately new species may arise.

NatureWorks Episodes

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

Diversity
1. Organisms are currently classified into five kingdoms (monera, protista, fungi, plantal, animalia) based on similarities in structure and
behavior.

NatureWorks Episodes

13. Species Diversity

2. A species is an important biological grouping of organisms whose members have similar structures, normally interbreed, and produce fertile offspring.

NatureWorks Episodes

13. Species Diversity

1. An ecosystem consists of all the organisms that live together and interact with each other and their physical environment.

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

2. Interactions in an ecosystem result from the transfer of matter and energy from producers to consumers and eventually to decomposers. The total amount of matter and energy in the system remains the same even though its form and location changes.

NatureWorks Episodes

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

3. Matter is recycled in an ecosystem, and energy which enters the system as sunlight is either stored in the bodies of organisms, used by
consumers to support their activities, or dissipated to the environment as heat energy. Loss of heat from an ecosystem is compensated for by continuous input of solar energy.

NatureWorks Episodes

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

1. Changes in the physical or biological conditions of an ecosystem can alter the diversity of species in the system. As the ecosystem changes, populations of organisms must adapt to these changes, move to another ecosystem, or become extinct.

NatureWorks Episodes

12. Population Dynamics
15. Invasive Species
16. Life at Risk

2. The size of populations in an ecosystem may increase or decrease as a result of the interrelationships among organisms, availability of resources, natural disasters, habitat changes, and pollution.

NatureWorks Episodes

12. Population Dynamics

Interaction of Humans Within Ecosystems
1. The extinction or introduction of species can affect the stability of ecosystems. With careful planning, humans may be able to sustain ecosystems for their use as well as preserve their biodiversity and natural beauty.
