Experiment 1: Tools for Lab Measurement Jonathan M. Brate October 6 th , 2008 Monday 2:00-5:00 Andrea Kravats Introduction: The purpose of Experiment 1 was to allow the class to get used to laboratory equipment, learn how to use the MeasureNet system by measuring the temperature of water before and after the probe was calibrated, and practice measuring mass and volume using different tools. Also, discovering which instruments are more accurate and precise that others.

Concepts from lecture that are being investigated in this experiment include how temperature can change over time and the fact that you can divide mass by density to find the actual volume of a container. A lab technique used to investigate these results were calibrating the MeasureNet system to measure the change in temperature of water over a time period of six hundred seconds while a beaker of water is on a hotplate. Another is a comparison of measurements by hand using different instruments such as a beaker, a pipet, a buret, and a graduated cylinder, and measurements found using another main objective of Experiment 1 which is to find actual volume, absolute error, and relative error of the measurements made by hand. Experimental Procedure: For Part A the procedure followed was that given in the lab manual: rd ed. pp. 1-4 to 1-5. For Part B the procedure followed was that given in the lab manual: Sprague, rd ed. pp. 1-5 to 1-10. Data and Results:
