A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

Cause-and-effect relationships are relationships between two or more variables or phenomena whereby one variable or event leads to a predictable response. Events have causes—sometimes simple, sometimes multi-faceted.
When floods or droughts occur (cause), the populations of organisms in the environment will change (effect).
Stability describes a system that does not change at the observed scale. In a stable system, a small disturbance will die out and the system will return to a stable state. Change in the system can come from modifying a factor or condition.
A stable ecosystem does not have large fluctuations in the population sizes of the organisms within it. If a condition in the ecosystem is significantly changed, the population sizes of some organisms will greatly increase and some will greatly decrease.
