Students should be able to describe the big bang theory and provide evidence used to support the theory; compare the characteristics and evolution of more massive stars to that of the sun.
Relate Earth’s ability to sustain life to the sun’s current stage in its stellar evolution and proximity to the Earth; use the Hertzsprung-Russel diagram to classify stars and use this classification to determine the projected stellar life cycle.
Analyze the variations in chemical compositions of stars of different masses and relate to the process of fusion and the star’s stage in its stellar evolution
Understand the connection between fusion of elements in stars and the presence and abundance of elements that make up our solar system and its contents, including living organisms
Analyze recent research findings (i.e., from NASA) about the terrestrial and gaseous planets; compare their atmospheres, internal composition, surface conditions, size, and rotation; and interpret why each planet has such characteristics as related
