There Are Major Earthquakes In Here!

We made a seismograph for scientific research. It is made of a box, a cup, some jewels, a pencil, a marker, and some string.


I did pretty good on my first one.


Nova really whacked it!

We are testing and measuring the earthquakes.

I am finding the MAJOR earthquake.

Nova is trying to be like me.

This was my best seismogram.
