investigate and describe how wind and water move soil and rock particles across the Earth's surface such as wind blowing sand into dunes on a beach or a river carrying rocks as it flows;
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.
investigate and describe how water can move rock and soil particles from one place to another;
investigate and describe how wind and water move soil and rock particles across the Earth's surface such as wind blowing sand into dunes on a beach or a river carrying rocks as it flows;
model and describe rapid changes in Earth's surface such as volcanic eruptions, earthquakes, and landslides.
model and describe slow changes to Earth's surface caused by weathering, erosion, and deposition from water, wind, and ice; and
Patterns are regular sequences that can be found throughout nature.
There is a relationship (pattern) between the strength of the water or wind and the size or weight of the particles it can move.
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.
The force of the wind or water causes the movement of soil or rock particles (effect).
