2 LABORATORY STRUCTURE AND OBJECTIVES Laboratory Structure and Objectives: Laboratory sections in BIO 102 are much smaller than lecture class in order to give students direct experience with a number of methods commonly used in biology and to provide opportunities for interactive learning, both with other students and with the teaching assistant (TA). Each of the exercises addresses an important biological question. These questions may require you to formulate hypotheses, design an experiment, collect data, answer a number of questions, or use a computer to analyze your data and interpret your results with respect to your initial hypotheses. Lecture and laboratory portions of the course complement each other but may not coincide exactly. You will generally be introduced to subjects in lecture first, however, so that you have adequate background for the exercises planned. Expectations: Along with completing each lab exercise and assignment, we expect you to: Attend all laboratory meetings . If you miss a lab, contact your TA immediately to try to attend another lab during the same week to complete the assignment. Because each lab exercise requires its own equipment, make-up labs will not be scheduled. Your lowest score for one of the weekly quizzes will be dropped and not calculated into your final lab average. Be on time . Most of the exercises require the full laboratory period (1 hour, 50 min) to complete. Important announcements or instructions for the day's exercise are given at the beginning of lab. The weekly quiz will be given and completed within the first 15 minutes of lab. Be prepared for each exercise and have your lab manual with you. The lab manual contains all the instructions for each assigned exercise. Read each week's exercise BEFORE coming to lab ; your quiz will include questions from the day’s lab to encourage you to be prepared. Your preparedness will make the lab exercises more useful to your overall learning experience. Students attending lab without their lab manual will lose 10% on their weekly quiz. Observe all lab safety rules. Follow instructions from your TA. No food or drink allowed in the lab EVER. No cell phones in the lab. Please leave the lab to talk or text. Wear closed-toe shoes to protect yourself. Students not following safety rules or the TA directions will be asked to leave the lab. Students with documented special needs should notify their TA immediately.
