# SAST3: Solar System Formation

Obtain, evaluate, and communicate information to illustrate the formation of the solar system and the properties of celestial objects within it.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SAST3.a**: Develop and use models to explain the formation of the solar system. (Clarification statement: This includes the nebular theory.)
- **SAST3.b**: Develop and use models to explain the chemical composition and characteristics of the Sun and other solar system objects. (Clarification statement: This should include addressing the role of nuclear fusion in the formation of elements in the sun and the role that hydrostatic equilibrium plays in the formation of different objects in the solar system.)
- **SAST3.c**: Ask questions to investigate and communicate major properties of our solar system bodies and the zones they inhabit. (Clarification statement: This includes planets, dwarf planets, major moons, asteroid belt, comets, Kuiper belt, and the Öort cloud.)
