Curriculum connections

Direct connections address a component of a standard, not the entire expectation. Supplemental connections support instruction or extend a lesson. Summaries are paraphrased from current official TEA standards.

Middle school

6th Grade Science

TEKS 6.1(G)Supplemental connection

Develop and use models representing phenomena, systems, processes or engineering solutions.

Develop and use an atomic model as enrichment; subatomic-particle arithmetic is not a direct grade-level content requirement.

7th Grade Science

TEKS 7.1(G)Supplemental connection

Develop and use models representing phenomena, systems, processes or engineering solutions.

Develop and use an atomic model as enrichment; subatomic-particle arithmetic is not a direct grade-level content requirement.

8th Grade Science

TEKS 8.1(G)Supplemental connection

Develop and use models representing phenomena, systems, processes or engineering solutions.

Develop and use an atomic model as enrichment; subatomic-particle arithmetic is not a direct grade-level content requirement.

High school

Chemistry

TEKS Chem.6(B)Direct connection

Describe atoms and ions, including subatomic particle masses, charges and locations.

Use particle models or counts alongside discussion of masses, charges and locations. Contrast fixed shells with the modern electron cloud.

TEKS Chem.6(A)Direct connection

Model the historical development of atomic theory.

Represent the Bohr stage and compare its limitations with other historical atomic models.

Integrated Physics & Chemistry

TEKS IPC.7(A)Direct connection

Model basic atomic structure and relate it to bonding, reactivity and periodic-table placement.

Model the atomic-structure component; bonding and reactivity need additional instruction.

TEKS IPC.7(D)Supplemental connection

Explain higher-to-lower electron transitions and emission of photons at different frequencies.

Use shells to discuss energy transitions with additional instruction on emitted photon frequencies.
