Develop a model based on evidence to illustrate the life span of the Sun and the role of nuclear fusion in the Sun’s core to release energy that eventually reaches Earth in the form of radiation.
Clarification statement: Emphasis is on the energy transfer mechanisms that allow energy from nuclear fusion in the Sun’s core to reach Earth. Examples of evidence for the model could include observations of the masses and lifetimes of other stars, as well as the ways that the Sun’s radiation varies due to sudden solar flares (“space weather”), the 11-year sunspot cycle, and non-cyclic variations over centuries.
Assessment boundary: Assessment does not include details of the atomic and sub-atomic processes involved with the Sun’s nuclear fusion.
Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.

NGSS Dimensions
Performance expectation HS-ESS1-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and using models: Develop a model based on evidence to illustrate the relationships between systems or between components of a system.
- The universe and its stars: The star called the sun is changing and will burn out over a lifespan of approximately 10 billion years.
- Energy in chemical processes and everyday life: Nuclear Fusion processes in the center of the sun release the energy that ultimately reaches Earth as radiation.
- Scale, proportion, and quantity: The significance of a phenomenon is dependent on the scale, proportion, and quantity at which it occurs.
