Subject: seismographs

Does anyone have a good model for building a simple seismograph for high
school students, one that would have the basic parts yet not be too
complicated? I would like to avoid any electronic parts if possible. I
just need it to demonstrate the basic functions of a seismograph.

Thank you.
