Need testing items for oscilloscope experiments

[PeterM]

My 12 year old grandson likes to learn and watch how an oscilloscope works.
I have a Tektronix 335, and like to help him, but I know less then he does.
So I'm wondering if there are any items I can buy from you that I could use
to show him how things work and look like on the screen. Any books on the
matter, for beginners of course would be much appreciated as well. I do have
the manual of course. I really like to have some electrical gadgets to
test, homemade ones are ok as well, I'll pay for your items..........Peter

You might try a photecell: point it at a flourescent light, or a
microphone, stuff like that.

I try anything to see what it looks like. I guess it depends on the probes
I have, right? thanks for the tip...........Peter
