SCIENCE.1.8.A — Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

S.1.6.B

explain and predict changes in materials caused by heating and cooling; and

S.1.8.A

investigate and describe applications of heat in everyday life such as cooking food or using a clothes dryer; and

S.1.8.B

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.

S.3.6.C

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

S.6.6.E

identify the formation of a new substance by using the evidence of a possible chemical change, including production of a gas, change in thermal energy, production of a precipitate, and color change.

S.7.6.C

distinguish between physical and chemical changes in matter;

S.8.6.B

use the periodic table to identify the atoms involved in chemical reactions;

IPC.8.A

investigate how changes in properties are indicative of chemical reactions such as hydrochloric acid with a metal, oxidation of metal, combustion, and neutralizing an acid with a base;

CHEM.9.B

differentiate among acid-base reactions, precipitation reactions, and oxidation-reduction reactions;

CHEM.12.D

predict products in acid-base reactions that form water; and

CHEM.13.C

classify processes as exothermic or endothermic and represent energy changes that occur in chemical reactions using thermochemical equations or graphical analysis; and

Recurring themes and concepts — Connections to the content

Recurring themes and concepts provide a connective structure for scientific ideas across disciplines. The connection(s) below show some ways that teachers can help students understand how the content they are learning fits into the broader understanding of science. These connections do not represent all possible connections that might be made but highlight some that are appropriate for this grade level.

Cause-and-effect relationships

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.

As heat is applied or removed (cause), changes to materials can be observed (effect). Heating an egg causes the egg to change color and become solid. Heating wet clothes in a dryer causes them to become dry.

Flow of energy and cycling of matter through systems

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.

Heat is used in everyday applications to change materials when energy flows into the materials.

Stability and change

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.
