Can you use things around your house or the hardware store to design your own seismograph to record earthquakes? Try building it to see if it would work. A good design should
- not do anything when there’s no vibration
- be able to record even small vibrations, like if you jump up and down next to it
Can you also make the seismograph tell you what direction the vibration is coming from? How about telling you how strong the vibrations were?
Build your own seismograph
Hint: one way to start is to hang a pen from a string so that it won’t move, with the tip just touching a piece of paper.
