Task: Make a seismograph that detects the Earths movement
Materials: wire, shoebox, washers, string, masking tape, maker, paper.
Original Construction: We made the base of the seismograph out of a box and cut a hole at the top. Through the hole we put the pencil and lots of washer to keep it stable.
Trials with the original construction: the original construction didn't work out because the pencil moved to much and couldn't record.
Modification 1# We added one set of wires to stabilize the pencil.
Trials with Modification 1# The pencil continued to move and the results weren't good we couldn't record anything.
Modification 2# We added a second set of wires lower so it stabilizes the pencil.
Trials with Modification 2# We had a couple trials here and they were all successful the seismograph worked.
Observations:
I noticed that for the seismograph to work we need to make the pencil stationary
I also Noticed that in order for the seismograph to work you need to move the desk in a specific order.
Conclusion: I conclude that Seismographs a really important to scientists. It helps them to measure the magnitude of an earthquake. We can measure when seismic waves start arriving, Scientists can warn people a couple minutes before the earthquakes climax so they get to safety. We can see the magnitude and damage using a seismograph.
Further Inquiry: Does the distance of the seismic waves or the focus affect the readings of the seismograph.
This seismograph was a complicated one but with multiple modifications you and Roy were able to make it work. It was complicated to get the readings on the paper that you wanted when the seismograph was attached to the table, but in the end we can clearly see moments of higher and lower seismic activity. You did well with the conclusion and realizing that the pen in fact needs to be stationary. Good job overall, however for this assignment you needed to have the lab format: guiding question, hypothesis, materials, procedure, data, data analysis, conclusion and further inquiry. Only parts of this were included. Please revise according to expectations.
