The Math lab evaluation Have you ever been to a place that is depressing‚ gloomy‚ and absolutely apathetic? If not then by all means make a point to go by and visit the math lab. As a student of the University of South Alabama I have been asked to evaluate the math lab by my supervisor. My supervisor had received various complaints by students‚ for that reason I have been asked to observe the math lab record what I saw and write down any suggestions for change. During this evaluation I will discuss

The Crime Lab Project is a non-profit corporation with a blog created for “raising awareness of public forensic science needs and challenges”(What is the Crime Lab Project 1). By reinforcing forensic science education and research‚ forensic science can contribute to a more just society‚ and in turn better everyone’s lives. ¨A recent congressionally mandated report by the National Academy of Sciences found¨ that there are serious deficiencies in the nation’s forensic science system and are in much

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

The goal of this lab was to create and purify DHFR from BL21 ecoli using column chromatography. To know if we isolate DHFR their will be one band at 53 KD or above 50 KD and in our desalted eluate page should have the highestOD₂₈₀ which translates to the highest enzyme activity .Column chromatography is a method used to purify individual chemical compounds from mixtures of compounds. The main advantage of column chromatography is the relatively low-cost and disposability of the stationary phase used

with this optional observation lab was a great experience overall‚ just as I had expected it to be. I was much more interested in participating in the observations versus sitting in a classroom every week and attending the labs like in 1010. The first event that I attended was the courtyard telescope setup on January 31st‚ in which we were observing a couple of different provinces and sunspots located about 10 o’clock region located directly on the sun. (See lab book for illustration.) We were

Introduction The general purpose of the Transformation Lab was to observe the difference in bacterial growth under differing media conditions to help understand the process of transformation and how it contributes to the life of living organisms. "Transformation" is what occurs when a cell receives and expresses

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity
