# SPS4: Fission, Fusion, and Decay

Obtain, evaluate, and communicate information to explain the changes in nuclear structure as a result of fission, fusion and radioactive decay.

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

## Expectations

- **SPS4.a**: Develop a model that illustrates how the nucleus changes as a result of fission and fusion.
- **SPS4.b**: Use mathematics and computational thinking to explain the process of half-life as it relates to radioactive decay.
- **SPS4.c**: Construct arguments based on evidence about the applications, benefits, and problems of nuclear energy as an alternative energy source.
