investigate and explain how soils such as sand and clay are formed by weathering of rock and by decomposition of plant and animal remains; and
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 document the properties of particle size, shape, texture, and color and the components of different types of soils such as topsoil, clay, and sand;
investigate and explain how soils such as sand and clay are formed by weathering of rock and by decomposition of plant and animal remains; and
Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.
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.
Weathering (effect) is caused by wind, water, and ice breaking larger rocks into smaller pieces.
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.
Soil types are composed of differing proportions of decomposed materials mixed with various types of weathered rock.
Matter and energy are conserved, changing forms but maintaining quantities. Energy flows within a system or between systems through transfers and transformations. Matter is cycled within systems through physical and chemical processes.
Weathering is the cycling of matter from large rocks to smaller particles.
