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.

The classification of different types of galaxies is dependent on the shapes and other characteristics (patterns) of those galaxies.
