SCIENCE.8.9.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.8.9.B
categorize galaxies as spiral, elliptical, and irregular and locate Earth's solar system within the Milky Way galaxy; and
illustrate the structure and components of our Milky Way galaxy and model the size, location, and movement of our solar system within it;
compare spiral, elliptical, irregular, dwarf, and active galaxies;
describe the Local Group and its relation to larger-scale structures in the universe; and
SCIENCE.8.9.B — Breakout of skills
Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.
The student is expected to
categorize galaxies as
elliptical
irregular
spiral
locate Earth’s solar system within the Milky Way galaxy
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.
