Big Ideas
  • The sun's life span and energy output are determined by nuclear fusion processes occurring in its core.
  • Developing and using models based on scientific evidence helps us understand how nuclear fusion drives the sun's radiation and its stages of life.
Essential Questions
  • How does nuclear fusion in the sun’s core sustain the sun over its life span?
  • What evidence helps us understand the different stages of the sun’s life cycle?
  • In what ways does the sun's emission of radiation relate to its internal fusion processes?
  • How do models help scientists illustrate and predict the life cycle of stars like the sun?
  • What role does evidence play in building accurate models of the sun’s energy production and life span?
