Lab 1Laboratory Fundamentals and Data Analysis5 September 2012Emily BrevilPartners:Ashley JohnsonVerline Jean
INTRODUCTION AND PURPOSE OF EXPERIMENT:In order for something to be valid according to the scientific method, it has to be agreeable with the predictions made and the answer can be found over and over again if it is repeated the same process and get the same results. In this lab, data was recorded in SI units, which is used in the scientific world so everyone will be on the same page. The purpose of this experiment is to learn how to take data, and familiarize oneself with the SI units, and learn to determine and errors in measurements.DIAGRAM:See graph paper
