For the first part of this section measurements were made with the dish pan empty - no water. A penny was used as the object. This section of the lab required more assistance from the instructor, only a couple images from this section was captured during the period.
Measurements were made along a diagonal away from the coin.
Measurements of the angle were begun directly over the coin. Angle measurements were repeated every ten centimeters. The measurement wwas of the angle displayed on the protractor.

As a thought for next term, on might take away the dishpan once the side of the pan eclipses the penny to allow measurements out to two meters. The 50 centimeter height worked well, but the in water data goes well out beyond penny eclipse.
The students used a bamboo skewer to "aim" at the coin.All measurements were made from a height of 50 cm. Measurements were repeated every 10 cm as the student moved away from the coin.

For the second part of the laboratory, the dish pan was filled with water until almost full. Measurements of the angle to the coin were repeated every ten centimeters. Student noted that the coin never really disappeared, measurements stopped out around two meters due to surface reflections from the water obscuring the coin.
