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. Grading 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 RULES FOR SAFE USE OF THE LABORATORY 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 it. 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. .
