Some of the pracs you are gonna are these, i ahve taken them straight from the syllabus :
- perform an investigation and gather first-hand information to observe the occurrence of different striation patterns for different pressures in discharge tubes
- perform an investigation to demonstrate and identify properties of cathode rays using discharge tubes:
* containing a Maltese cross
* containing electric plates
* with a fluorescent display screen
* containing a glass wheel
- perform an investigation to demonstrate the production and reception of radio waves
- perform an investigation to model the behaviour of semiconductors including the creation of a hole or positive charge on the atom that has lost the electron and the movement of electrons and holes in opposite directions when an electric field is applied across the semiconductor
- perform an investigation to demonstrate magnetic levitation
im not sure which ones use high voltages but im pretty sure you can do these if your school has the resources and as for the ones that you dont do, your teacher should give you a report on it anyway
