You are expected to attend every lab. If you must be absent, see or phone your lab instructor or leave a message with the department secretary (593-2290) as soon
as possible. It may be possible to attend a lab later in the week. There will be no make-up quizzes or exams without a verifiable and University approved excuse.
RESPECT DEADLINES: Make-up quizzes, if allowed, are subject to a 10% penalty per day. Your training as a scientist includes learning to work within deadlines. Plan ahead and do not needlessly lose points. If you feel extenuating circumstances are preventing your progress, contact your instructor well ahead of the exam date to discuss the problem.
CLEANLINESS AND ORDER ARE IMPORTANT: A neat and clean lab is essential for the work we will be doing this quarter. Each student is responsible for maintaining the lab in good order. Failure to cooperate will result in lowering of your lab grade (a warning will be given for the first offense and a 5 point deduction for each subsequent offense).
ACADEMIC MISCONDUCT: Academic misconduct refers to dishonesty in examinations (looking on another's paper, allowing another to see your answers, using unauthorized crib notes, etc); presenting the ideas or writings of another as one's own (plagiarism); or giving false information to a faculty or staff member. If you are found to be involved in academic misconduct you will be treated in the most severe manner possible. This will include a grade of zero on the work in question and automatic referral to the Office of the Judiciaries. Further action may include F in the course, a record of the incidence in your permanent file and/or expulsion from the university. Refer to the Undergraduate Catalog for details.
GENERAL INSTRUCTIONS FOR LABORATORY WORK:
What you do in the lab helps you to correlate portions of the textbook and the Bios 172 lecture material with actual study of animal specimens. In some exercises you also gain experience in dissections, by which you can see structural relations and make comparisons with your own eyes.
Before lab, read the pages in both Buchsbaum and Bios 172 textbook and any handouts you have received. Read the objectives for the week and coordinate the microscope slides and specimens you will look at and dissections you will make with the information in the texts. When you arrive at lab, take notes as your lab instructor orients you to the location of the various materials in lab and instructs you how to proceed.
It is expected that you will use your scheduled lab time well by taking advantages of the resources available to you in lab (instructors, fellow students, computer, etc.). If you finish early go back over each objective to be sure you have not missed anything. POP QUIZZES that will be incorporated into the lab grade may be given near the end of the lab period at the discretion of the lab instructor.
TIPS ON MAKING DRAWINGS:
Drawings represent a shorthand method of recording observations. They must be accurate, original and reflect what you see and know. Drawing requires you to use the same observation skills you need for your nature journals. Look closely and pay attention to detail. Drawing exactly what you see will help you fix a mental picture of the structures and proper labeling of the structures will also provide you with a permanent record of all that you have seen. Careful, complete drawings will prove to be an excellent study guide for quizzes and the final exam (and you can save them to show your parents that you actually do go to class).
You need not be an artist to make scientific drawings. Before you begin, study the relationship of the structures in your specimen and look at the shape and relative size of each part you will draw. Plan the placement of the drawing on the page so that there will be enough room for labels. Use the entire space. Wee-little, dinky drawings are of no use.
Print labels horizontally, never at an angle. Draw a straight line from the structure to the label; never cross label lines. Estimate the magnification below each drawing (e.g., X40).
Write the genus name of the organism, begin it with a capital letter and underline it.
TIPS ON DISSECTING:
Follow the instructions and proceed with care. The objective is to separate and expose organs to see their relationships. Working blindly, without the instructions, may result in the destruction of parts before you have had an opportunity to identify and draw them. Learn the functions of the organs you dissect.
Please take proper care of lab equipment. All materials must be cleaned and in the proper place before you leave.
Lab instructors and assistants are here to help--ASK LOTS OF QUESTIONS! ENJOY LIFE!
