Water Levels in Wells
1) Which Well
Number were you assigned? (Well numbers are 1, 2, and 3)
2) Find the depth to water in your well.
3) Find the total depth of the well.
4) Determine the volume of water
in the well.
5) Determine how many five-gallon
buckets of water it would take to hold half the volume
of water in the well.

the time (to the nearest second) before you begin (or use a stopwatch
starting at time zero).
b) Remove from the well
the volume you calculated in Step 5. Immediately
after withdrawing this volume of water, measure depth to water
7) Monitor water
level frequently for the next several minutes,
recording time and depth measurements.
8) Prepare a graph of the data you
recorded in Steps 6 and 7. Plot time on the horizontal axis, and
depth on the vertical. Label the graph with your names and the
Number, and post the graph on the chalkboard.
9) In no more than two paragraphs, explain your
observations and any differences between the graphs for the different

of steps for a tester to follow) for such a test.

including a neat table showing

hand in one report per group. All group
members will receive the same grade on the work.
