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.
compare the properties of puddles, ponds, streams, rivers, lakes, and oceans, including color, clarity, size, shape, and whether it is freshwater or saltwater; and
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;
Patterns are regular sequences that can be found throughout nature.
Patterns can be seen in human trade routes, migration of oceanic organisms, and ocean currents.
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 humans harvest too many organisms of the same species (cause), then the population of that species cannot recover to sustainable levels (effect). When fertilizer runoff from human agriculture enters the ocean (cause), it can cause algal blooms (effect), depleting the dissolved oxygen in the water and causing dead zones.
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 ocean system consists of the biotic and abiotic factors in the ocean and the currents that move them around. Human dependence on ocean systems for food, transportation, and energy production can impact parts of the system.
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.
Ocean systems have been stable for millennia; however, whaling in the 19th century (change) caused a decline in top predator populations, destabilizing oceanic food webs.
