Date report submitted: June 18‚ 2015 Title: Lab Techniques and Measurements PURPOSE: The purpose of this experiment is for the students to get a better knowledge with the laboratory tools and techniques. This experiment taught me how to convert between SI units and standard American units of mass‚ length‚ temperature‚ volume and time as well as how to measure the units. Students become proficient in laboratory techniques such as measuring temperature and volume and calculating within them. Procedure:

PHY 114: General Physics Laboratory Lab 1: Absorption of Nuclear Radiation 09/04/13 Abstract Nuclear physics was practiced to find the value of tau. After 8 trials of using a G-M counter and 8 different mass thicknesses of polyethylene‚ a graph was formed and tau was calculated to be 0.1931 cm^2/g‚ an error of 3.57% from the accepted value of 0.2 cm^2/g. Experiment was also used as an intro to using basic lab equipment‚ computer programs and calculating errors. With many different
