Nuclear Fusion Core Simulator, Years 11–12
Students vary stellar-core temperature, density and hydrogen content and observe changes in proton–proton fusion rate, energy output and pressure support. The full interactive is available to licensed Education Universe users.
Years 11–12, UndergraduateExplorer
Learning outcomes
- Describe proton–proton fusion in a stellar core.
- Relate core temperature and density to fusion rate.
- Explain how fusion supports a star against gravity.
Teaching guidance
Change one variable at a time and ask students to predict the direction of change in energy output.
