APE MAN

TEKS 8.1(G)Instructional support

Represent atomic structure as modeling practice and high-school preparation; subatomic-particle arithmetic is enrichment, not current 8.6(B) content.

A hands-on atomic structure tool with a dry-erase surface for working through science concepts.

Chemistry

Interactive Bohr Model

TEKS 8.1(G)Instructional support

Use and critique an atomic model as enrichment. This is not a direct match to identifying atoms in reactions under 8.6(B).

Students place electrons into orbital slots and build a physical picture of atomic structure.

Topographic Maps

TEKS 8.1(G)Instructional support

Develop and use a terrain model. Current grade 8 content does not explicitly require topographic contour-map reading.

Bring a three-dimensional perspective to your lessons on terrain and topographic maps.

Physics

Speed Formula Triangle

TEKS 8.2(C)Instructional support

Practice quantitative relationships using motion data; average speed is prior-learning support, not a grade 8 speed-calculation content requirement.

Work with the relationship between speed, distance and time.
