Explore how a smoke detector works in a home. Make smoke in a kitchen to trigger the beeping sound of a smoke alarm. Look at a circuit diagram and magnified view to see how an isotope interacts with ionised gases within a circuit gap. Test a range of isotopes to see which will work in the smoke detector.
Objective
Students explore the movement of ions in a smoke detector.
Students identify isotopes suitable for use in a smoke detector
