describe how some changes caused by heat may be reversed such as melting butter and other changes cannot be reversed such as cooking an egg or baking a cake.
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.
explain and predict changes in materials caused by heating and cooling; and
investigate and describe applications of heat in everyday life such as cooking food or using a clothes dryer; and
describe how some changes caused by heat may be reversed such as melting butter and other changes cannot be reversed such as cooking an egg or baking a cake.
conduct a descriptive investigation to explain how physical properties can be changed through processes such as cutting, folding, sanding, melting, or freezing; and
predict, observe, and record changes in the state of matter caused by heating or cooling in a variety of substances such as ice becoming liquid water, condensation forming on the outside of a glass, or liquid water being heated to the point of becoming water vapor (gas); and
Energy flows within a system or between systems through transfers and transformations. Matter is cycled within systems through physical and chemical processes. It is important to note that in kindergarten–grade 2, the foundation of flow of energy and cycling of matter is built by identifying the forms of energy and properties of matter. In grades 3–8, students learn that matter and energy are conserved, changing forms but maintaining quantities.
Energy flows into materials, causing changes that may be reversed by removing the energy from the materials.
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.
In most instances, materials remain in an unchanging, stable state. Modifying a condition or factor (heat applied or removed) can change one or more physical properties of the material.
