Capacitors
This is a topic in which there is plenty of scope for practical work, and the experiments tend to be reliable. The topic is also rather mathematical; the use of exponential equations can reinforce students' experience with radioactive decay equations, if this has already been covered.
It is unlikely that your students will have met capacitors before unless they have studied some electronics, perhaps in technology.
