Phases of the Moon

9: Organisms and environments. The student knows and understands that living organisms within an ecosystem interact with one another and with their environment.

9.A: The student is expected to: investigate that most producers need sunlight, water, and carbon dioxide to make their own food, while consumers are dependent on other organisms for food; and

Forest Ecosystem
Prairie Ecosystem

9.B: The student is expected to: describe the flow of energy through food webs, beginning with the Sun, and predict how changes in the ecosystem affect the food web.

Forest Ecosystem

10: Organisms and environments. The student knows that organisms undergo similar life processes and have structures and behaviors that help them survive within their environment.

10.B: The student is expected to: explore and describe examples of traits that are inherited from parents to offspring such as eye color and shapes of leaves and behaviors that are learned such as reading a book and a wolf pack teaching their pups to hunt effectively; and

Inheritance

10.C: The student is expected to: explore, illustrate, and compare life cycles in living organisms such as beetles, crickets, radishes, or lima beans.
