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.
Human activities may cause changes to abiotic factors in the environment, leading to changes in a region's climate. For example, deforestation (cause) changes the availability of plants that absorb carbon dioxide, which may increase carbon dioxide in the atmosphere (effect).
It is important to consider how changes in scale, proportion, or quantity affect a system’s structure or performance. Scale refers to the size of an object in relation to another object or its environment. Proportion is the ratio of one quantity to another. Quantity is a count of a set of objects or a measurement of a substance.
Various natural events can impact the proportion of gasses in the atmosphere and the quantity of heat energy that those gasses can absorb.
A system is a whole made of parts that work together. It has components and boundaries. It can interact with or be part of other systems.
The climate is a system which is impacted by the interactions between the hydrosphere, atmosphere, and human activities that affect them.
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.
Climate is a stable pattern of weather in a region over a long period, but it can be disrupted by human activities (change).
