Unformatted text preview: y of thinking about Cell and Molecular Biology issues changed, but the rate at which our knowledge is being accumulated has increased dramatically. We feel that these changes make it imperative that we emphasize the processes by which knowledge is generated and changed. In addition, it is our hope that we encourage the students to actively participate in these exercises rather than passively absorb facts and figures. A concluding thought. This manual is presented as a guide for your efforts in lab. In order for it to have its intended outcome, you must read it carefully and think about what you read. This thought is summarized in the sage words of an emeritus faculty member of this department: “You can’t read this stuff like you’re reading a comic book!” The Laboratory Examination: A comprehensive laboratory examination is part of the course curriculum. It will be given week 10 8/28/12 - further details regarding the exam are given in lab. One half of your BIOL 5LA course grade will be based upon your performance on this exam. Therefore, you must do well on this examination if you expect a B or an A in the course. The coverage of the exam is outlined, in part, in the “Learning Goals/Desired Outcomes” sections that appear at the end of each laboratory exercise. These clearly and explicitly state what is expected of you for each of the labs. You should refer to these listings both before and after each of the laboratory exercises. You should be able to prepare written responses (in your lab notebook) for most of the listed items. Do this as soon as possible after you have completed each lab. These responses should be written at the highest level possible with the available resources; your lecture notes, the Campbell text, and the lab manual. Further, you should review these responses periodically in the time between when they were written and the exam. Your TA has been instructed to monitor your progress in this activity and to help you in this effort. The exam will also cover topics that should be a part of the write-ups that you will prepare for the two experimental labs. iii Biology 05LA – Fall Quarter 2012 Introduction Record Keeping and Some Suggestions about Lab Preparation The laboratory notebook is your record of your work. As mentioned above, you will be examined on all laboratory exercises performed this quarter. The laboratory notebook will become a valuable resource for preparation for these evaluations. You are encouraged to keep a record of your laboratory activities in a manner that will make your notebook entries useful for later study. Some suggested guidelines follow. The labs for Biology 5LA may be classified into three basic types: “tool box” laboratories, investigative laboratories, and the tutorial laboratories. Each type has somewhat different requirements for adequate preparation and record keeping. 1) The “toolbox” laboratories. Labs 1 & 2 fall into this category. These exercises are so named because they are intended to provide some basic laboratory skills and/or conceptual tools that are required for Biology 5LA and many other science courses that you will be taking here at UCR. a) Before your lab period, you should carefully read the entire lab exercise in this manual – including the “Learning Goals/Desired Outcomes” sections that are posted at the end of each lab exercise. Once this is done you should write down (in a sentence or two) the purpose of each part of the day’s lab exercise. b) During the lab period, you should describe all of the observations you have made or the techniques you have learned in your lab notebook. For the former, accurately labeled and scaled drawings or sketches will often serve this purpose. It might be necessary to accompany these drawings with some verbal commentary when there are features of your subject that do not lend themselves to being recorded in the form of a diagram. For the latter you should focus on the aspects of the technique that you found particularly difficult or different than what you had expected. c) After the lab period, you should make sure that you can adequately respond to every item on the “Learning Goals/Desired Outcomes” listings found at the end of each lab. Further, you should write down any problems you had with the techniques, the observations, and etc. If you had such problems, you should attend your TA’s office hours so that you can discuss them with your TA. 2) The investigative laboratories. Labs 5 & 6 fall into this category. These are open-ended experimental labs that are truly investigative in nature. In addition to being instructional about particular subject areas of the course, these laboratories are also intended to familiarize you with the process of Hypothesis-Based Science (a thorough discussion will be presented in Lab 4). a) Before your lab period, you should prepare the “Introduction” for the day’s lab exercise following the instructions presented in Lab 4. A copy of this introduction will be handed for grading in on the day tha...
