Description of Laboratories

 

The laboratories for this course will be a mixture of computer-based human physiology labs, dissection, and more traditional ÒwetÓ physiological labs. 

 

The computer labs will use software and hardware that is part of the Vernier Human Physiology Laboratory package.  This package was chosen partly because it allows modern physiological monitoring in humans (i.e., you) to illustrate physiological principles.  The other attractive feature of the Vernier labs is that the software allows students to design their own experiments and measure several physiological variables simultaneously.  This provides substantial flexibility you can take advantage of in designing your independent projects.

 

The ÒwetÓ labs will involve experiments on invertebrate animals like cockroaches, crayfish, and water bears.  Invertebrates are used here because of animal care considerations, because more than 95% of living animals are invertebrates, and because the basic principles underlying their physiological functioning are identical to those of vertebrates usually.  Indeed, much of the early and modern research that gives us understanding of these processes involves invertebrate animals.

 

We will also have demonstrations set up for you to examine in many labs and A.D.A.M. Interactive anatomy software to allow you to compare what you see in invertebrates with human anatomy and functioning.

Grading

 

The laboratory portion of the course will count for 100 points or 25% of your final course grade.  Laboratory grades will be based on performance in quizzes (best 5 of 6 @ 5 pts each for 25 pts total; dates noted above by asterisks), written reports and a lab practical (best 2 of 3 @ 15 pts each for 30 pts total), a written proposal for your independent project at 5 pts, a written report for your independent project at 20 pts, oral presentations @ 10 pts, and general participation and completion of worksheets (+/- grading) @ 10 pts. 

 

Please note the following:

 

1)    We will use the best of the two marks for your reports on the class wide experiments and lab practical.  While you may elect to use your report grades and not take the lab practical (i.e., the lab practical grade would be the one ÔdroppedÕ), we will require that you complete both reports on the class-wide lab exercises.  Failure to hand one of these in will result in a grade of 0 points being assigned for that lab report and this grade being one of the two that is used for calculating the final lab grade.

2)    Late laboratory reports will be docked 10% of the report credit for each day they are late.  Laboratory reports will be due in your scheduled laboratory period during the week indicated on the schedule above or at times and dates announced by your T.A..

3)    The report you write for your independent project will be averaged into the final lab grade calculation (i.e., this is not one of the reports which can be dropped from this calculation).

4)    Participation marks will be based on your general participation in laboratory exercises with a component from ÒcitizenshipÓ (Clean up is expected.  Do not leave it to your T.A. to clean up after labs; this is everyoneÕs responsibility).

Laboratory Practices and Safety

 

All students are expected to follow safety guidelines announced by the T.A.  in laboratory.  Emergency procedures, exit routes, and fire extinguisher locations will be discussed during the first laboratory period.  Special clothing in the form of full, enclosed shoes and full-length pants will not be required for some laboratories and your T.A. will inform you if it will be necessary for a given laboratory exercise during the preceding laboratory period.  Please be conscientious and cooperative in this regard. 

 

Attendance

 

Attendance of all of your scheduled laboratory sections is required for credit.  Unexcused absences from a section will result in zero credit being given for that dayÕs quiz, no credit for that weekÕs report or presentation if applicable, and subtraction of 50% from the participation portion of your grade (i.e., 0.625% of your final course grade plus the point value of the report and/or quiz that you miss).  A missed report or quiz for which a zero grade is given will be averaged into your final grade calculation – these will not be used as the Òone that is droppedÓ.  There will be no exceptions to this policy.  Remember that it is your responsibility to inform your T.A. that you will miss/have missed a section, preferably in advance, and provide documentation outlining university –sanctioned reasons for your absence.  We discourage attending other lab sections, but this may be allowed in unusual circumstances.

 

Note on the writing of laboratory reports

 

Goals: We understand that these reports represent a considerable effort.  Our goal is to give you experience in this form of writing to help you better understand the concepts being explored and, more generally, to help you succeed in the future.  Success in the work force and on aptitude tests for graduate and professional schools increasingly depends on solid written and oral communication skills.  Some individuals are Ôborn writers,Õ but it requires hard work for the vast majority of us and this is the reason for the emphasis on writing in the sophomore portion of the Zoology core sequence.

 

Individual Reports: You will be working in pairs or groups of four in the laboratory this semester.  We encourage you to talk about and work through your data together.  However, the actual writing for the reports you will complete is intended to be your work and only your work.  You can and should work together to talk about interpretations of your data, but you should be working alone when you sit down to write the actual reports.  Writing your own reports means more than token word changes.  Having students write something together and then make minor word changes for their separate reports is not what we are looking for. 

 

Proper Attribution of Sources:  Academic and intellectual work primarily produces ideas.  It is critical to give proper credit for ideas and analyses to those who formulated them.  For this reason, plagiarism is a very serious issue that is at the heart of concerns about academic integrity.  We expect all work presented in lab reports to be your own unless properly referenced.  If you have questions about whether something represents plagiarism or whether you are giving credit to an author or authors properly, please do ask your TA. for guidance.
