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 deflection-system. The pupils should know how the wave form is built up. Therefore you start with the deflection of the Y-Plates and then you move on to the deflections of the X-Plates. 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.

Tricks
it's not easy to explain such an instrument in English. But have a try!
