The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

Abstract This report contains the background information on gram positive and gram negative bacteria‚ which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of identification used are also described in this report to give an explanation

A streak culture was performed on a Tryptic Soy Agar Plate for isolation and purity and then incubated at 37 degrees Celsius for 24 hours. A gram stain was performed to determine whether the bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed‚ there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating‚ identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance
