Biology 160 Laboratory Syllabus by W656u9JN


									Biology 160 Laboratory Syllabus
Fall 2011   Spokane Community College

General Goals
The goal of the laboratory for Biology 160 is to provide
students with hands on experience that will reinforce important
concepts being taught in lecture. The laboratory provides
students with a working knowledge of lecture topics with hands-
on exercises that require technical expertise and critical
thinking. The lab provides the student with a deeper
understanding of biological concepts, gives an appreciation for
how science is done, provides experiences with collecting data
and helps develop technical writing and problem solving skills.
Upon successful completion of this course students will
understand the structure of the cell and how it is studied, be
able to describe how energy transfer drives living systems and
understand the structural and functional aspects of genetic
systems in living organisms. As you work on these concepts you
will be introduced to several biological techniques including
microscopy, chromatography, and DNA analysis.
Learning Activities
Exercises in the laboratory will consist of reading assignments,
laboratory exercises, group activities, quizzes and exams.
Laboratory Regulations
Laboratory attendance is required. If you do not attend lab you
will not be able to receive credit for that lab. There will be
no make-ups on lab quizzes or lab assessments. If you miss a
lab, you should get the data from your lab partner; you are
still responsible for the information.
Laboratory Participation and Professionalism (LPP) grade: You
will earn 75 points for reliable laboratory participation and
professionalism. To earn the LPP points, you must:
(1) Turn in a flowchart at the beginning of each laboratory that
outlines the protocol to be performed that day. This will
require you to refer to your laboratory schedule PRIOR to lab.
Next, you must read the lab(s) in your lab manual and write your
flowchart(s) to demonstrate that you are prepared and know what
you will be doing when you walk into the lab. The flowcharts may
be computer generated or hand-written, but MUST be turned in
before the lab begins and must be detailed enough that you could
perform the lab(s) by flowchart guidance alone. No flowcharts
will be accepted after the lab starts. If you fail to turn in
your flow chart on time, four points will be deducted from your
LPP grade.
(2) Arrive on time for each laboratory session. If you arrive
late to lab, two points will be deducted from your LPP grade.
(3) Stay in lab until you are dismissed. Leaving the laboratory
early will result in the loss of two LPP points.
(4) Attend every laboratory session. Ten points will be
deducted from your LPP grade for each laboratory that you miss
Microscope Assignment
You will be assigned a microscope. Always use the same
microscope and be sure to clean it properly before putting it
away. These scopes are used by several labs and consequently any
damaged or misused microscopes will be noted immediately.
Your lab grade will become a part of the total grade for the
course. Your lab performance will be measured as follows:
Lab quizzes: there are 15 scheduled lab quizzes. Each will be
worth from 10-20 points and will be given during the first 5
minutes of class. Please be aware if you are late or miss a quiz
no makeup will be allowed. Each quiz will cover the most recent
lab unless otherwise stated.
Summary reports: three summary reports are scheduled. Each will
be worth 30 points and should be done with your lab group.
Written reports are limited to two double spaced, typewritten
pages each, plus one additional page of data tables or graphs.
No hand-written reports will be accepted. The intent of the
reports is for you to consolidate the information you have
gathered from selected labs into a concise summary of your
observations and conclusions. These reports should focus
especially on your independent investigation. Specific
instructions on preparation and grading will be given in lab.
Lab notebook checks: Several random checks of lab manuals for
completion of results will be made during the term. Each is
worth 5 points. Lab book checks cannot be made up.
Lab assessments: There will be two lab assessments. These will
be practical exams showing materials, set-ups or asking
questions about the laboratory exercises and the results of
those exercises.
How to Succeed
To be successful in the laboratory portion of Biology 160 the
student should read the exercise in the lab manual PRIOR to the
lab period. Careful preparation before each lab including
reading the assigned material and familiarizing yourself with
the scheduled activities will produce better results in the lab
and on graded exercises. Answer all questions for which lab work
is not necessary. If you do not understand something in the
reading, make a note in your laboratory notebook and ask me to
explain before you begin work in the laboratory. The only dumb
questions are those that are never asked. It is your
responsibility to know what you are doing! Don't be late for
lab, and plan on remaining in the lab for the entire lab period.
Don't fool yourself. You will need the entire time to do a
decent job.
General Safety Regulations
You will be using glassware in several labs such as beakers and
test tubes. In the event that any glass is broken, consult your
instructor concerning cleanup procedures. Exercise caution near
hot plates. Take care when using scissors, knives, and razor
blades. In the event that you or your lab partners are cut,
consult your instructor concerning first aid procedures
1. Food and drink of any type cannot be brought into the lab at
any time. You may not put makeup on in the lab. Even if you
think everything is "clean", it may not be. This laboratory is
used by other classes throughout the semester, many of which use
preserved specimens and potentially toxic materials.
2. Never be in the lab alone. Accidents happen.
3. Before there is even a possibility that you will need them,
identify the sink, eyewash stations, and phone. Be sure you
understand how to exit the lab and building in an emergency.
4. Keep the top of your lab bench clear and clean, and keep the
floor around your bench clear. Coats, backpacks, etc. should be
placed well away from areas where others will be working.
5. Wash your hands thoroughly at the end of each lab, even if no
hazardous materials were used. You can never be sure what others
had on their hands when they handled things in the lab.
6. If anything spills, notify your instructor and get
instructions for cleaning it up. Wash any spilled material from
your skin or eyes immediately.
7. Assume that all human body fluids (e.g. blood, urine, saliva)
are infectious. When handling these fluids, wear gloves,
protective eye wear and a lab coat and take extra precautions to
avoid spills. All biological materials should be deposited in
orange biohazard bags and broken glass, glass slides and sharp
objects should be placed in a sharp’s container. Clean off your
bench top thoroughly even if you think no fluid was spilled on
8. Keep hair and loose clothing secured when in lab. You don’t
want to contaminate these by being dipped into the specimens or
caught by others moving around in the lab.
9. Please notify your instructor immediately if you have any
negative reactions (e.g. breathing problems, rashes) to
materials used in the lab. Please notify your instructor in
advance if you are pregnant or have any medical problems, which
might affect your safety in the lab.
10. Shorts and sandals are not appropriate laboratory attire.
11. Children are never permitted in the laboratory.
12. Only approved experiments are permitted.
