Measurement and Uncertainties


Complete the measurements in each of the following stations in sequence

Station A: Mass of a Beaker of Water

Select a clean empty beaker from the variety provided - co-ordinate with the other members of the class to insure that there is a wide variety of beaker sizes used, i.e., 50, 100, 200, 400 and 600 ml. Using a meter stick or ruler, measure the diameter of your beaker and record the value in your notebook. Partially fill your beaker with water at room temperature from the reservoir in the lab. Then carefully place on an analytical balance to measure an initial mass. Using a stopwatch, remeasure the mass at 30 second intervals for a total of four minutes (9 total measurements).

 

 

Station B: Measuring Resistance

Choose ten resistors of each type from the two types of resistors provided. Using multimeters determine the resistance of each resistor

 

 

Station C: Measuring an unknown mass

Using a spring and the set of known masses devise a method for measuring the unknown mass.

 

 

Station D:

  1. Speed of an electron beam

    2. Determine the velocity of the spot on the screen of the oscilloscope.

  2. Volume of water in a burette

    3. Determine the volume of water in the burette.

  3. Diameter of a wire

Measure the diameter of each of the three wires.
