Experiment 1. Introduction to Scientific Measurement and Experimental Error - Determining the Density of Glass
The purpose of this experiment is to demonstrate the uncertainty of scientific measurements due to a number of possible errors in the measurement process. First, the student will make a number of measurements, including length, weight, and liquid volume determinations. Second, the student will determine the variation in measurements of the same items by multiple students. The student will, as an option, determine the standard deviation (variability) of these measurements. Third, as an additional optional exercise for this experiment, the student may determine the density of glass by measuring the mass and volume of glass shards.
