Principal emphasis is placed upon learning the fundamental biological characteristics of microorganisms, and in particular, of the prokaryotes. However, significant emphasis is placed also upon the relationship of microorganisms and the field of microbiology to the broader sphere of human history, social, ethical, and medical issues. STUDENT EXPECTATIONS Students are expected to bring to this the foundational knowledge provided in the Intro Biology 101 and 131 courses, including such topics as - Molecular biology ` - Energy harvesting and utilization - Genetics - Eukaryotic cellular biology - DNA structure and function - Photosynthesis Students should review these topics as required during the semester, using prior course notes and textbooks, and/or the textbook used for this course. ATTENDANCE POLICY Attendance will be taken in lectures and laboratories. I must be notified at least ONE WEEK in advance if you need to miss a lecture or laboratory due to a field trip, athletic event, etc. Because of the nature of certain laboratory exercises, make-ups may not be possible, and no make-ups will be given for unexcused absences from laboratories. Extraordinary circumstances will be dealt with on an individual basis. Students will need to periodically return at non-laboratory periods to complete an exercise or to observe results. There is adequate flexibility in the timing of these periods to accommodate most student schedules. Unavoidable conflicts should be discussed with me. GRADING POLICY Your final grade will be determined as follows. Lecture exams 3 x .110 Final exam Quizzes 4 x . 25 Laboratory grades . . . . 330 points 150 100 180 ----Total . 760 points An unexcused absence from lab will be a 20 point deduction. Grading Scale 97 - 100% = A+ 93 - 96% = A 90 - 92% = A87 - 89% = B+ 83 - 86% = B 80 - 82% = B77 - 79% = C+ 73 - 76% = C 70 - 72% = C67 - 69% = D+ 63 - 66% = D 60 - 62% = D< 60% = F Safe conduct in the lab: You are expected to follow safety practices as instructed the lab. Point deductions from your lab grade may result from repeated failure to dispose of materials in a correct and timely manner, adequately label cultures (name, organism and date), remove old cultures from the incubators, keep work space clean, and wear lab coat when working in the lab. 3 EXAMS AND QUIZZES Exams and quizzes will cover lecture materials and assigned readings. The final exam will be comprehensive. I must be notified at least one week in advance if you cannot attend class the day of an exam or quiz due to an athletic event, field trip, etc, then, at which time we will arrange an alternative exam time. You may not be allowed to makeup an exam if I receive "last minute" notification. There will be no make up exams for unexcused absences. Extraordinary circumstances will be dealt with on an individual basis. If you have special needs because of a documented learning disability or other disability, please see me immediately to discuss possible accommodations. Academic Dishonesty Academic dishonesty within the academic community is a very serious matter, because dishonesty destroys the basic trust necessary for a healthy education environment. Academic dishonesty is any treatment or representation of work as if one were fully responsible for it, when it is in fact the work of another person. Academic dishonesty includes cheating, plagiarism, theft, or improper manipulation of laboratory or research data or theft of services. A substantiated case of academic dishonesty may result in disciplinary action including a ‘0' on the assignment, a failing grade in the course, or expulsion from the College. LABORATORY GRADES (180 points) Results of Exercises (90 points) — For 9 lab exercises you will be required to turn in your results and their interpretation on the pages provided at the end of each exercise chapter. One copy of the results will be turned in for each lab group, at the beginning of the next lab period (unless indicated otherwise). Generally, ½ - 1 point deductions are imposed for instances of performing protocols incorrectly, incomplete work, misinterpretation of results, poor responses in written answers, and turning in ‘messy’ work. Late submissions will be docked 10% per day. Microorganism practical (20 points) — You will be asked to identify types of eukaryotic microorganisms and some of their characteristics while viewing projection slides. Gram Stain Practical (20 points) — Using a slant culture containing an unknown bacterium, you will prepare a Gram stain to identify the Gram reaction, and the shape and arrangement of the cells. You will also be graded on the quality of the smear and staining. Identification of Unknowns Lab exercise (30 points) — You will be asked to identify 3 unknown bacteria to the level of genus using techniques and skills learned previously during the semester. Each student will work independently as a demonstration of the skills you have acquired during the semester. Semester Unknown (20 points) — Students can earn extra credit for maintenance, analysis and identification of their semester unknowns. Each group will isolate, characterize, tentatively identify a bacterial unknown. The unknown will be isolated during the Basic Bacteriologic Techniques exercise and maintained throughout the semester in pure form. At the end of the semester each student will turn in a streak plate of the unknown demonstrating its colonial properties and purity; each group will turn in a summary of the properties that you determined during the semester, and a tentative identification. 4 Microorganisms and Historical Figures that you should become familiar with during this semester. Given the name you should be able to identify relevant topics, and vice versa.
