Demonstrate understanding of stars and planetary systems
This standard asks you to show you understand how stars work and how planets form around them. You need to describe what stars are like (including where they sit on the Hertzsprung-Russell diagram), the different stages of a star's life from birth to death, and how planets and moons form. You'll apply this knowledge to explain real examples and interpret diagrams.
You identify and describe the main features of stars, stages of star life, and moon/planet formation processes, showing you understand the basic concepts.
You explain how star characteristics link to the Hertzsprung-Russell diagram, use diagrams to support your thinking, and connect ideas like gravity and mass to how stars evolve and how moons form.
You give detailed explanations of how luminosity, surface area, fusion, and gravity all work together in star evolution and death, justify moon formation theories with evidence, and link original star mass to final outcomes like neutron stars or black holes.
