Stories 8-12


STANDARD 3: LIFE SCIENCE Grades 8-12

LIFE SCIENCE – The student will develop an understanding of the cell, molecular basis of heredity, biological evolution, interdependence of organisms, matter, energy, and organization in living systems, and the behavior of organisms.


▲ = High School Assessed Indicator

Benchmark 4: The student will understand the interdependence of organisms and their interaction with the physical environment.


  • ▲ understands the distribution and abundance of organisms and populations in ecosystems are limited by the carrying capacity.
  • understands organisms cooperate and compete in complex, interdependent relationships
  • understands human beings live within and impact ecosystems.

Teacher Notes:

The life science standards provide a framework for a variety of courses in the life sciences. Ecology concepts are key to understanding life; these indicators provide a framework for local curriculum for courses such as biology, botany, and zoology.

Learning Science in the Outdoors: Varied experiences in the outdoors make natural processes less abstract and are critical to developing scientific literacy. Teachers are encouraged to create outdoor learning experiences for their students.




STANDARD 3: LIFE SCIENCE Grades 8-12

LIFE SCIENCE – The student will develop an understanding of the cell, molecular basis of heredity, biological evolution, interdependence of organisms, matter, energy, and organization in living systems, and the behavior of organisms.

Benchmark 6: The student will understand the behavior of animals.


The student …

1. ▲ understands animals have behavioral responses to internal changes and to external stimuli.

2. understands most multicellular animals have nervous systems that underlie behavior.

3. understands behaviors are often adaptive when viewed in terms of survival and reproductive success.


Additional Specificity

1. a. Responses to external stimuli can result from interactions with the organism's own species and others, as well as environmental changes.

b. These responses can be innate and/or learned.

c. Animals often live in unpredictable environments, and so their behavior must be flexible enough to deal with uncertainty and change.

2. a. Nervous systems are formed from specialized cells that conduct signals rapidly through the long cell extensions that make up nerves.

b. The nerve cells communicate with each other by secreting specific excitatory and inhibitory molecules.

c. Sense organs, specialized cells that detect light, sound, touch and specific chemicals, enable animals to monitor what is going on in the world around them.

3. a. Common behaviors include seeking food, seeking mates, raising young, avoiding predators, and regulating body temperature.

b. Some organisms live in groups and have social behaviors that benefit both the individual and the group.
