   Grade 3
3. Adaptations in physical structure or behavior may improve an organisms' chance for survival.

a. Students know plants and animals have structures that serve different functions for growth, survival, and reproduction.

NatureWorks Episodes

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

b. Students know examples of diverse life forms in different environments, such as oceans, deserts, tundra, forests, grasslands, and wetlands.

NatureWorks Episodes

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

c. Students know living things cause changes in the environment in which they live: some of these changes are detrimental t the organism or other organisms, and some are beneficial.

NatureWorks Episodes

9. The Wildlife Web I 
10. The Wildlife  Web II
11. Decomposers and Scavengers
12. Population Dynamics
14. Niche
15. Invasive Species
16. Life at Risk

d. Students know when the environment changes, some plants and animals survive and reproduce; others die or move to new locations.

NatureWorks Episodes

12. Population Dynamics
16. Life at Risk

e. Students know that some kinds of organisms that once lived on Earth have completely disappeared and that some of those resembled others that are alive today.

16. Life at Risk
   Grade 4

2. All organisms need energy and matter to live and grow.

a. Students know that plants are the primary source of matter and energy entering most food chains.

NatureWorks Episodes

9. The Wildlife Web I 

b. Students know producers and consumers are related in food chains and food webs and may compete with each other for resources in an ecosystem.

NatureWorks Episodes

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

c. Students know decomposers, including fungi, insects, and microorganisms, recycle matter from dead plants and animals.

NatureWorks Episodes

11. Decomposers and Scavengers
   
   Grade 5

2. 2. Plants and animals have structures for respiration, digestion, waste disposal, and
transport of materials. As a basis for understanding this concept:

e. Students know how sugar, water, and minerals are transported in a vascular plant.
f. Students know plants use carbon dioxide (CO 2 ) and energy from sunlight to build
molecules of sugar and release oxygen.

NatureWorks Episodes

9. The Wildlife Web I 

g. Students know plant and animal cells break down sugar to obtain energy, a process
resulting in carbon dioxide (CO 2 ) and water (respiration).

NatureWorks Episodes

9. The Wildlife Web I 
   Grade 6

5. Organisms in ecosystems exchange energy and nutrients among themselves and
with the environment. As a basis for understanding this concept:

a. Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs.

NatureWorks Episodes

9. The Wildlife Web I 

b. Students know matter is transferred over time from one organism to others in the
food web and between organisms and the physical environment.

NatureWorks Episodes

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

c. Students know populations of organisms can be categorized by the functions they
serve in an ecosystem.

NatureWorks Episodes

14. Niche

d. Students know different kinds of organisms may play similar ecological roles in similar biomes.

NatureWorks Episodes

14. Niche

e. Students know the number and types of organisms an ecosystem can support
depends on the resources available and on abiotic factors, such as quantities of
light and water, a range of temperatures, and soil composition.

NatureWorks Episodes

12. Population Dynamics
