- A 12 pound weight
-A 16ft deep pool
-An underwater clipboard
-An underwater marker
-Scuba equipment
-A ruler
-Scuba equipment
-Graduated cylinder

Problem statement # 2
-Bike pump (with pressure measurer)
-Gradual cylinder (thin)
-Thin stick
-2 liter soda bottle
-Tape
-Shrader valve

Method


Problem statement #1
1. Set up 20ft stick/ruler in pool
2. Tie weight to end of stick/ruler and make sure
the ruler/stick stays straight
3. Go down in pool in 2 ft increments holding
graduated cylinder upside down, and measure the
volume of the bubble each time you descend 2ft
4. Do process as many times as you can

Problem Statement #2
1. Tape graduated cylinder to stick and place stick
inside soda bottle
2. screw on shrader valve hook up to bike pump
3. Pump in 14.7 PSI increments, recording volume of
air bubble each time
4. Do not exceed 88.2 PSI
5. Do experiment as many times as you wish, and
average results
*note-pressure on graduated cylinder is already 14.7
PSI because of atmosphere
