The laboratory component is a REQUIRED part of the introductory biology
course. The laboratory is designed to provide an investigative-based laboratory
experience with concepts covered in the course. Students will usually
work in pairs and are strongly encouraged to participate in class discussions.
1. ATTENDANCE TO YOUR ASSIGNED LABORATORY SECTION IS MANDATORY!
2. UNEXCUSED ABSENCES CANNOT BE MADE UP and will result in the following
- A single unexcused absence
from lab will result in a reduction in the final
lab grade by one letter grade.
- TWO or more unexcused absences
will result in a failure in the lab and the course.
3. EXCUSED ABSENCES MUST BE MADE UP IN ANOTHER SECTION THAT SAME WEEK
(with instructor approval).
- Excused absences must be approved
by the dean or by coach (student athletes must provide the instructor
with dates for missed labs prior to lab)
- If a student is unable to make up a single EXCUSED lab
it will result in a reduction in the final lab grade
by one letter grade. If a student is unable
to make up TWO or more EXCUSED labs the student will receive
an incomplete for the course and thus must
re-take BI 170.
The following materials are required for each student and must be brought
to each lab session:
. Lab manual (provided to you during your first lab meeting)
• Bound, quad ruled lab notebook (provided to you during your first
• Lab coat (required at all times in the laboratory; can be purchased
in bookstore or online: Allheart,
Uniform Advantage, Pulse
Uniform, Uniform City or
• Closed toe shoes
• Pens, pencils, scissors, ruler
- Your bound quad-ruled laboratory notebook must
be devoted solely to the laboratory is required of each student.
- Your laboratory manual must be brought to
every lab or you will be asked to leave.
- A laboratory coat must be worn in the lab
at all times. Students without their coat will be asked to leave the
- Before lab, students should prepare by reading the entire assigned
laboratory, and finishing the pre-laboratory writing assignment on a
sheet of paper.
- You will not be allowed to enter the laboratory with open-toed shoes.
- We cannot allow any students to attend lab sections other than their
own. Make-up laboratories are only permitted under very special circumstances
and by permission of the instructor.
- The use of cell phones or stereo headphones/music devices in class
is disruptive to others. Please turn them OFF and have them put away
while in class.
- There is ABSOLUTELY NO FOOD OR DRINK permitted in the laboratories
at any time - this includes OPEN LAB times - violators will be asked
to leave the lab.
- Individual students will not be permitted to leave lab until the entire
class is dismissed by the instructor.
Course Learning Objectives
To ensure success in subsequent biology courses, you will be learning
basic laboratory skills in BI 170 labs. Each student is expected to master
the following skills by the end of the semester:
- Having a completed lab notebook at start of each lab
as outlined in INSTRUCTIONS FOR THE LABORATORY NOTEBOOK section of your
- Having Pre-labs completed on a separate sheet of paper
as outlined below
- Ability to develop a testable hypothesis and a prediction
for an experiment
- Ability to identify dependent and independent variables
in an experiment
- Ability to graph data correctly - assign variables to
correct axes, use Excel to graph means and include standard deviation
as y-error bars
- Ability to focus a microscope independently, to view
a specimen while increasing magnification, and to draw a proper microscope
- Ability to accurately pipet using glass pipets
Components of the Lab
- Lab Notebooks
On the first day of lab we will give you a lab notebook that is to be
used exclusively for this course. Experiments will be recorded in the
notebooks and they will be checked for completeness at the end of each
lab period. Incomplete notebooks will be penalized. Although discussion
of labs and assigned questions with other students is encouraged, plagiarism
is obviously prohibited. Please review the guidelines in the document
INSTRUCTIONS FOR THE LABORATORY NOTEBOOK, found in the lab manual.
- Computers and Software
Several lab exercises will require use of a computer for data analysis
and graphing. You will need to use Microsoft Word and Excel or equivalent
You are expected to read the lab and complete any written pre-lab prior
to coming to lab to perform the experiments. Written pre-labs may include
the purpose for each experiment as well as some assigned terminology
- Lab Performance and Execution
You are expected to come to each lab prepared and follow all instructions
and all safety guidelines. It is also expected that you will complete
all clean up prior to leaving the lab.
YYou will be expected to take short open-notebook quizzes at the start
of most lab periods. These will cover the topic of that lab and the
previous week's lab. You will be able to use your pre-lab writing assignment
as a reference during your quiz, so COME PREPARED! Because everyone
can have a bad day, your lowest quiz score will be dropped.
- Lab Report
You will be asked to write a formal lab report on one of the laboratory
experiments. This will follow the format of a standard journal article,
which will be introduced to you, and is described in your laboratory
manual Appendices section. A rough draft of the report will be required,
and students will receive feedback for revising their final lab report.
- Lab Practicals
Two lab practicals will be included to test the laboratory concepts
and skills covered in the course.
- Open Labs
The laboratory classrooms will be open outside of scheduled lab times
so that you may come in and review material or complete lab notebook
write ups (if your instructor allows you to do so). Open lab hours are
posted on the doors to the labs. NO FOOD OR DRINK ARE PERMITTED IN THE
LAB DURING OPEN LABS. You will be asked to leave if you violate this
The laboratory component represents 25% of your final course grade. You
must pass the laboratory component of BI 170 in order to pass the BI 170
- Lab Notebook: 7.5% (based on overall notebook quality and 3 labs in
- Quizzes: 2.5%
- Lab performance/execution: 2%
- Lab Report: 5% (rough draft is required)
- Lab Practicals: 8% (4% each)
