Durchführung 
First of all you start with explaining the
theory of the cathode ray tube. You start by explaining the electron
gun
and then move on to the deflectionsystem. The
pupils should know how the wave form is built up. Therefore you start
with the deflection of the YPlates and then you move on to the
deflections of the XPlates. Always discuss zero voltage, dc voltage
and ac voltage. After this the students work on their own. Give each of
them
a frequency and let them determine the time of period and the voltage. 
Resultate möglichst quantitative 
Every student has at least once worked with
an oscilloscope and is able to determine at least the time of period
and the voltage. 
Bemerkungen & Tricks 
it's not easy to explain such an instrument
in English. But have a try!
