Objective: Find the reaction of the wave (seismograph) when the weight attached

I.  GUIDING QUESTION/S:  
What will occur when different weights are added to the surface wave (Finding the work of seismographs)?

II.HYPOTHESIS:
Kyle: I believe that depending on which or how much the weight, the solution of the balance will vary.
Lukas Hypothesis: I Think that the balance will if we differ if you add more or less weight.
Philipp: I think if we change the weight it will swing different. I think if it gets more weight it will swing bigger.

III.  Exploration (PLAN & DO A TEST):

Materials:

Previous Fail Trial Materials:

Red Pen
Blue Pen
Chicken Wire
Scissors
Board Game for the bottom
Tape
Wagon Wood Wheel
Paper
Weight
String

New Trial Materials:

Pen
Weight
Tape
Paper
Ruler
Science Discovery Book
Chicken Wire
Table (As an earthquake)

Procedure (New Seismograph Procedure):

(After Gathering the Materials above)

1. First attach/tape the tip of 2 rulers to the wall horizontally and parallel
2. By using the tap attach the chicken wire to the rulers.
3. Then connect the pen to the wire, which holds the weight. (The objective is to see, if adding weight will affect the result )
4. The pen should be stationary; the pen will be producing seismogram.
5. When the pen with weight is connected with the rulers, slowly prepare the papers and the table to produce earthquake (magnitude).
6. Let one person move the paper slowly when one or two shakes and create earthquake movements.
7. As a result, the seismogram will show the wave vibrations.

Data of Seismogram Analysis:
                     


Kyle’s Analysis of the Seismogram:

The Graph shown above shows our final data of the new seismograph we made. As the seismograph reacted by the magnitude of the table, the wavelength and the frequency of the seismogram altered. The monitor up there shows how fast and how hard the magnitude reacted. In final consideration, the new seismograph we made was efficient, simple, and easy. I had discover that the seismogram will show difference results when depending on the weight; as more weights are included the shorter the wavelength will be and faster the vibration or the movement.

C.  Analysis of Data:

Kyle’s Analysis: I had figured out that the result and the affect of the wave movements will alter depending on how many weights are added to the pen.

Philipp’s Analysis: I figured out that if there is more weight on the pen then the pen will swing worse and smaller. We had the problem that we put the weight next to the pen and not over it. That’s why the first try was not working.(The weight was pulling the pen to the side where it was attached)

Lukas Analysis: I found out that if we add more weights to the pen it will swing less than the pen without weights. We had problems with the weight positioning. That gave us some dificulties.

IV.  Concept Acquisition (CONCLUSION):  

Kyle’s Conclusion: There are several conclusions to write down; mistakes and trials were made throughout the tests, some were successful but majorities weren’t. As our class started the seismograph lab, my group partners had left without a sign. Though this wasn’t the major problem it could had caused a huge impact. But the problem of this lab was that many attempts were made, however not a single we expected came out. All of us had discovered that the pen should had been stationary, if not we had to adjust the box (it was arduous to adjust since the box was about to be ripped). As my group mates knew this matter, we needed support or a change, we lost control when we were trying to aim higher.

Philipp’s Conclusion: I think that we had a lot of problems with the seismograph lab. We tried to fix up things, we can’t fix up. We also had the problem that we were sick and couldn’t come to school. We were trying ti finish it but our seismograph did not want to work. We finished our writing part very fast but we could not build the seismograph. After all we our teacher helped us and gave us a good idea and we build a good seismograph. I think that it was still fun to make our own seismograph. I think our last try of the seismograph worked pretty good. Our mistakes were that we tried to make the seismograph with to pens. After that the whole seismograph broke. That was the end of our idea. I think an
improvement was our second seismograph because it worked very good.

Lukas Conclusion: I think that we
