Density Formula Triangles

TEKS 6.6(D)Content connection

Calculate density from measured mass and volume, then compare substances' densities relative to fluids. Pair the triangle with a relative-density investigation.

TEKS 6.2(C)Instructional support

Use mathematical calculations to assess quantitative relationships in mass and volume data.

Cover the value you need and the triangle shows whether to multiply or divide—so students set up density problems instead of guessing at the algebra.

Chemistry

Interactive Bohr Model

TEKS 6.1(G)Instructional support

Develop and use physical models. Atomic structure beyond atoms as building blocks is enrichment, not a grade-level subatomic-particle requirement.

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

Topographic Maps

TEKS 6.1(G)Instructional support

Use a layered terrain model to represent landforms and discuss the model's limitations. Contour-map interpretation is not a direct grade-level content requirement.

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

Physics

Speed Formula Triangle

TEKS 6.2(C)Instructional support

Practice quantitative relationships with distance and time data. Average-speed calculations are enrichment, not a grade 6 motion content requirement.

Work with the relationship between speed, distance and time.

Lunar Cycle Science Manipulative

TEKS 6.1(G)Instructional support

Develop and use a lunar-cycle model as enrichment. Lunar phases are not a direct current grade 6 content requirement; do not confuse phases with seasons or tides.

Model the lunar cycle and discuss the changing appearance of the Moon.
