Electricity can seem like an abstract concept to students that it is difficult to picture and they find it tricky to describe what is happening inside a circuit or device. It needs to approached with clarification of key definitions (even when these have been covered before, such as current) and with a critical eye on any models used during teaching. Some students also find it difficult to relate practical work observations to models used and calculations undertaken so this process should be included in lesson and guided by the teacher.
Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to Health and Safety and that they carry an appropriate risk assessment. Further information is provided in our Health and Safety guidance.
