Measurements and Standards
Purpose:
A quick introduction to the concept of units of measure.
Procedure:
 To give concept of primary and secondary standards, use aluminum block to 'calibrate' meter stick and calipers.
 Measurement of fundamental units and their standards.
 Length: Beyond common examples already shown, discuss use of monochromatic light as a standard reproducible anywhere.
 Time: From ordinary to atomic clock, i.e., show clock, pendulum, electronic oscillator, stable atomic clock.
 Mass: Explain gravitiational and inertial mass. Compare unknown to known masses on balance and obtain density of three red blocks and determine the material they are made of.
