Section:

The student is expected to:

(a) Introduction.

(A) Within the natural environment, students know that earth materials have properties that are constantly changing due to Earth's forces. The students learn that the natural world consists of resources, including renewable and nonrenewable, and their responsibility to conserve our natural resources for future generations.  The students will recognize that our major source of energy is the Sun.

(B) Within the living environment, students know and understand that living organisms within an ecosystem interact with one another and with their environment. The students will recognize that plants and animals have basic needs, and they are met through a flow of energy known as food webs. Students will explore how all living organisms go through a life cycle and that adaptations enable organisms to survive in their ecosystem.

(b) Knowledge and skills.

7. (A) examine properties of soils, including color and texture, capacity to retain water, and ability to support the growth of plants;

Soils and Decomposition

7. (B) observe and identify slow changes to Earth's surface caused by weathering, erosion, and deposition from water, wind, and ice; and

Landscape Formation screens

8. (A) measure and record changes in weather and make predictions using weather maps, weather symbols, and a map key

Refer to Climate screens

8. (B) describe and illustrate the continuous movement of water above and on the surface of Earth through the water cycle and explain the role of the Sun as a major source of energy in this process; and

Water Cycle

Mechanisms: Water Cycle; Endangered: Climate

9. (A) investigate that most producers [plants] need sunlight, water, and carbon dioxide to make their own food, while consumers [animals] are dependent on other organisms for food [, producers, and consumers] ; and

Food Web screens

Refer to Dependency Web screens

Build-A- Desert

9. (B) describe the flow of energy through food webs, beginning with the Sun, and predict how changes in the ecosystem affect the food web such as a fire in a forest.

10. (A) explore how adaptations enable organisms to survive in their environment such as comparing birds' beaks and leaves on plants;

Adaptations: Animal, Plant; refer to Organism screens

Biodiversity; Study screens: refer to Organism screens

Study screens: Adaptations; Organism screens

10. (B) demonstrate that some likenesses between parents and offspring are inherited, passed from generation to generation such as eye color in humans or shapes of leaves in plants. Other likenesses are learned such as table manners or reading a book and seals balancing balls on their noses; and
