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.


ATTENDANCE TO YOUR ASSIGNED LABORATORY SECTION IS MANDATORY! Labs that are missed for unexcused absences can NOT be made up. A single unexcused absence from lab will result in a reduction in the final lab grade by one letter grade. TWO labs missed for unexcused absences will result in a failure in the lab (which means a failure for the course).

Labs missed for EXCUSED absences (requiring written approval from the Dean or coach) must be made up by attendance to another lab section within that same week (with instructor approval). 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.

Required materials:
The following materials are required for each student and must be brought to each lab session: Lab manual
• Bound, quad ruled lab notebook
• Lab coat
(lab manual, lab notebook and a lab coat will be given to you during your first lab meeting)
• Closed toe shoes
• Pens, pencils, scissors, ruler


  • Your grid-style laboratory notebook should be devoted solely to the laboratory is required of each student. This must be brought to every lab or you will be asked to leave.
  • A laboratory coat (available at the bookstore) must be worn in the lab at all times. Students without their coat will be asked to leave the lab.
  • Before lab, students should prepare by reading the entire assigned laboratory, and writing the hypothesis (or purpose) and predictions for that lab in the lab notebook.
  • 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. See "Attendance Policy," above.
  • 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.
  • Individual students will not be permitted to leave lab until the entire class is dismissed by the instructor.

Components of the Lab

  1. Lab Notebooks
    Notebooks are sold pre-packaged with the laboratory manual and are exclusively for use in this course. The instructions for the notebook will be found inside the front cover. 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.
  2. 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 software such as Pages and Numbers (Apple), or Google Docs and Google Sheets.
  3. Pre-labs
    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 definitions.
  4. Quizzes
    You 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.
  5. Lab Report
    You will be asked to write a formal lab report on your Genotyping for Sickle Cell Anemia experiment. This will follow the format of a standard journal article, which will be introduced to you, and is described in your laboratory manual. A rough draft of the report will be required, and students will receive feedback for revising their final lab report.
  6. Lab Practicals
    Two lab practicals will be included to test the laboratory concepts and skills covered in the course.
  7. 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 safety rule.

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 course.

  • Lab Notebook: 7.5% (based on overall notebook quality and 3 labs in detail)
  • Weekly Quizzes: 2.5%
  • Lab Report: 5% (rough draft is required)
  • Lab Practicals: 10% (5% each)
