I Have To Read That???

As a Biological Sciences major, we are often assigned many articles, journals, books, and lab manuals to read. During my first semester of my sophomore year, we had to read and perform lab experiments for my Chemistry 107 class. I took the class once a week from 2:30-5:05. The book was entitled "Chemistry II Lab Manual" by Tina Masterson.
The lab manual included roughly around twenty different lab experiments for us to perform. These experiments included titrations, solution preparation, melting/boiling points, and solubility. Each experiment varied in the amount of time taken to complete each one. While most of the experiments took the entire two and a half hours to complete, some took only an hour and a half. In the manual, Mrs. Masterson is discussing many of the areas that make up the chemistry world today. As previously stated, many of these areas include titrations, solution preparation, melting/boiling points, and solubility. Because I took many biology classes in high school and my freshman year of college, I am pretty knowledgable when it comes to biology and chemistry.  The motivation behind the creation of this lab manual was to teach students the proper techniques and procedures behind performing certain experiments in a lab setting. There are many things to consider when reading this lab manual and performing the experiments. One of the major issues is health/safety. During these experiments, many toxic chemicals and reagants are used so it is very wise to take all necessary precautions. The first safety rule is that one must always wear safety goggles while in the lab. In addition, if any toxic chemical touches the skin, the first thing one should do is wash the surface with tap water.
As previously stated, the author's name is Tina Masterson. She is over the chemistry department here at the University of Southern Mississippi. She is a really smart and nice lady. She is always in the chemistry tutor ceneter willing to lend a helping hand to anyone who is having trouble with their work. Her purpose of writing this manual is to ensure that her students are following proper directions and learning about chemistry in the proper manner. I know this because Mrs. Masterson is a very passionate person and knows quite a lot of information about chemistry. The intended audience for the Chemistry II Lab Manual is anyone who may be interested in chemistry or students who are enrolled in the course. Directly, Mrs. Masterson is targeting one certain group of people. That group of people is the chemistry students here at Southern Miss. Because of the language used in this manual, Mrs. Masterson is assuming that the students using the manual have a chemistry background and already have a basis with the chemistry concept. She uses terms that people outside of the discourse community of chemistry students may not know about. These terms include flasks, beakers, and burets. Her tone is strong and very direct.
In my opinion, the writer did an excellent job in writing the lab manual. Her directions were very easy to understand and follow. They led to a very successful  and fun lab experience. However, one improvement that could have been made is that she could have taken out some of the steps in certain experiments because they were very repetitive. Overall, the Chemistry II Lab Manual was a success, and I received a B in the class. :)
