2 Introduction The primary objective of this course is to meet one semester of the science requirement for liberal arts majors, but it also serves to meet the chemistry requirement for Fire Science. In order to meet these varied needs we will spend the majority of time learning basic principles in chemistry. By the end of this course students will have learned about the basic substances in Nature; atomic theory and how it explains chemical bonding. They will also learn about physical and chemical reactions, and the energy changes that occur. They will learn how to balance standard chemical equations, along with basic stoichiometry. They will learn about Boyle s and Charles Gas Laws and how to apply them. They will learn about acids and bases and ph and practical applications. They will learn about oxidation and reduction; application to batteries. They will have a brief introduction to organic substances. They will learn about polymers, both synthetic and natural. They will also be introduced to very basic biochemistry, primarily carbohydrates, fats and proteins. They will learn about nucleic acids and their role in protein synthesis. There will also be a lab component to the course. There will be 1 experiment each week. A detailed discussion of the lab requirements will be given during lab. Each lab is designed to illustrate some concept that has been discussed in lecture. An attempt has been made to make these labs as interesting and enjoyable as possible. A lab report is required for each experiment, which will be graded. These grades will comprise about 33% of your final course grade. This package also contains a list of topics that we will cover during lecture. The pages dealing with these topics in your text are listed with the topics. You are strongly advised to read this material before coming to class. You will benefit much more from the lecture if you have read the material than if you have not. You will all receive a copy of my notes, which will be the basis for our class discussions. This package also contains a list of recommended homework for each chapter. This is a minimum amount that you should do. This does not prevent you from trying more or all of the questions within and at the end of each chapter. The more you do, the easier it will be for you to understand the material. Homework will not be collected or graded, however. It will be up to you to keep up with this work. The answers to all practice examples throughout the chapters plus the answers to the questions marked in red at the ends of each chapter are available in Appendix C at the back of the textbook and I am available during office hours or after class to explain any of the questions. There will be 3 exams given during class time. No make-up exams will be given, but to account for an unforeseen absence from an exam, your lowest grade will be dropped. If you miss an exam, that will be your drop. In addition to these 3 exams, there will be a final exam covering the entire course, which must be taken in order to get a grade in this course. Also, periodic short quizzes may be given, but all quizzes will be preannounced. There will be NO surprise quizzes. Each exam will be worth 100 points. The final exam will be worth 150 points. The quizzes will be worth 10 points each. The lowest quiz grade will be dropped. The lab reports are worth 20 points each. The lowest 2 lab report grades will be dropped. Your final grade will be determined by adding all your grades and dividing by the maximum total number of points possible and multiplying by 100.

3 Below is a list of grades: A - 93 and above A B B B C C D D F - < 60 Finally, you will be supplied with a CPS Response pad to use during class. These will be used during the lectures to monitor your understanding of the material presented. You will receive a grade for this class participation. However, it will only count as extra credit. The maximum points available are 30. This can add up to approximately 5% added to your final average. Although the points are extra credit, the use of the response pad is NOT optional. These bonus points added can easily mean the difference between a C or a B or the difference between a B and an A. The procedure for registering your response pad and its use, so you can receive these bonus points will be explained in the first class period. A schedule of experiments to be done during this course appears later in this package. The write-up for each experiment is available on the Internet at and then migrating to my Home Page under Faculty web sites and clicking the Course tab under the heading picture, and then clicking lab manual Each lab can be then printed out. If you do not have access to the internet at home, you are all permitted access on campus. You must print out each lab before you come to lab. You are strongly urged to read each experiment before coming to lab. Make sure you print out the correct lab. Check the schedule in this package. The experiments on the Web site are not in the same order. This Course Information Package is also available at that Web site.
