My results showed the trial with the greatest amplitude was trial three because the table was being hit with the most force, making the table and the pen move more than the other three trials.
The trial with the least amplitude was trial two because the table was hit with the least amount of pressure.
While observing the experiment, I noticed that the more vibrations or higher magnitude resulted in a higher amplitude on the seismograph.
The harder the table was being hit, the higher the amplitude rose. I believe the results are accurate because while the experiment was in progress, the frame moved at the same rate as the table.
Hypothesis: An increase in the magnitude of vibrations will result in an increase in amplitude of the seismograph.
Materials: clamp, metal bar, piece of string, rubber bands (2), table, pencil, two people Procedure: I laced a piece of paper directly beneath the pen and the clamp stand.
The 'then' part of the statement is an educated guess on the outcome of the experiment. Results include experimental (raw) data in the form of well-labeled tables, graphs, drawings and other observations.
A good lab report explains exactly what you have done.
Measuring the distance from the top and bottom of the spike represented the amplitude.
The data from each seismograph was recorded in the table on the following page.
Conclusion: This lab investigated how the magnitude of vibrations affects the amplitude of a seismograph.
In order to study the problem we created three magnitudes of movement and measured the amplitude of each with a seismograph.
