How does the system behave and how does it 'feel'?

When I squeeze the bottle, water climbs up the vertical tube, and the water

in the pressure tube moves up.

Length of the air column in units of your measuring device:

I'm just going to use standard meter stick, which measures up to millimeters.

I honestly chose this because it is the measurement that I am most

comfortable with. I haven't had much practice with levels of reduction, and

the other measurements are smaller than I think I can read precisely

Your report of the vertical position of the first mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials.

10.9 cm.

I had a paper meter stick that I taped together very carefully. I held it up to

the tube and measured very carefully the length of the air column.

Your report of the vertical position of the second mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials.

10.9 cm

5.0 cm, 8.6 cm

5.1 cm, 8.7 cm

5.3 cm, 8.8 cm

5.3 cm, 8.9 cm

Your report of the vertical position of the highest mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials.

5.2 cm, 10.3 cm

5.1 cm, 10.5 cm

5.2 cm, 10.4 cm

5.2 cm, 10.5 cm

5.3 cm, 10.6 cm

Your report of the vertical position of the 'in-between' mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials.

5.3 cm, 11.5 cm

5.4 cm, 11.4 cm

5.5 cm, 11.3 cm

5.7 cm, 11.5 cm

5.6 cm, 11.6 cm

about an hour and a half.(getting the set up right took me a really long time)
