π Topic Summary
Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing a tremendous amount of energy. This is the energy source that powers the Sun and other stars. In high school, demonstrating nuclear fusion directly is challenging due to the extreme temperatures and pressures required. However, we can explore the principles through analogies and thought experiments.
This activity will explore the core concepts of nuclear fusion. We'll touch on key vocabulary, explore the energy aspects, and think critically about the challenges and potential of fusion energy.
