SCIENCE.7.8.B — 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.3.8.A

identify everyday examples of energy, including light, sound, thermal, and mechanical; and

S.7.8.B

investigate how thermal energy moves in a predictable pattern from warmer to cooler until all substances within the system reach thermal equilibrium; and

CHEM.10.A

describe the postulates of the kinetic molecular theory;

CHEM.13.A

explain everyday examples that illustrate the four laws of thermodynamics;

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.

Patterns

Patterns are regular sequences that can be found throughout nature.

Thermal energy moves in a pattern from warmer to colder, and students can make predictions based on this pattern.

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.

The movement of energy from warmer to cooler areas (cause) will eventually result in a balance of temperature (effect).

Flow of energy and cycling of matter through systems

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.

Thermal energy moves between particles of substances from warmer to cooler substances. The flow of energy continues until both substances reach a balance in temperature (thermal equilibrium).

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.

Thermal energy flows between the particles of substances, moving from warmer to cooler (change). The flow of energy continues until both substances reach thermal equilibrium (stability).

Cross-curricular Connections

The cross-curricular connections are designed to help educators make content connections between the science TEKS and math, English language arts and reading, social studies, and technology applications. The standards below illustrate alignment between grade level content areas which may help educators develop cross-curricular lessons. These connections do not represent all possible connections that might be made.
