Students will prepare for the lab by reading a description of gravity meter operation. After a brief quiz, the students will assemble with the meter in the stairwell of the building and measure the elevation to each level. After this, they will take multiple measurements on each level going up the stairwell, and then repeat the measurements on the way down, making sure to record the data values and the time. They will then convert the raw data to mGal using the conversion factor from the meter, and then use the data from the lower level to correct for drift. The corrected data are then plotted vs. elevation, a slope determined and the slope compared to the elevation correction term. The students will then write a lab report describing the procedure, presenting the data and their analysis, example calculations and their results. Has minimal/no quantitative component
