Principle

The pupils should recognize

that one can demonstrate electrical charging with an electroscope but that the type of charge is not revealed,
that from the extent of pointer swing the strength of the charge can be inferred,
that using a known polarity of charge on the electroscope the type of charge of a test body can be determined,
that one can discharge the electroscope by touching with the hand.

Benefits

Quick and easy experiment for qualitatively understanding of electrostatic phenomena

Tasks

What does an electroscope indicate? Investigate how an electroscope reacts when you touch it with an electrically-charged object and then, afterwards with the hand.
