Understand laboratory report format and grading criteria. Use computers to assist in report preparation, as well as preparation of graphs using a spreadsheet and/or scientific programming package. Learn about data limitations and experimental uncertainties. Objective 2: Become proficient at handling chemicals and using laboratory equipment. Be trained in handling acids, bases, flammable and toxic substances. Be trained in proper use of balances, burets, ph meters, spectrometers. Objective 3: Reinforce material presented in the General Chemistry II recitation course. Perform experiments on colligative properties and chemical kinetics Perform experiments illustrating chemical equilibrium and acid base theory Perform experiments related to chemical analysis, electrochemistry, transition metal complexes, and organic chemistry. Students who successfully complete this course should have deepened their knowledge of the theoretical material discussed in General Chemistry II lecture. All topics covered involve fundamental principles of chemistry and they should serve as a basis for future studies in biology, chemistry, and other science.

If not, you need to register. Select Sign up, Activate your Net ID and follow the instructions. You will need to know your USF ID Card Number: (ten digits). You should find yourself in Blackboard click on Courses and Gen Chem II. After a little surfing you will find (search), which lists all members of the class and their addresses and Tools Check Grade or Calendar. Student Learning Outcomes: At the end of the course, students should demonstrate an appreciation and understanding of the scientific method of inquiry General Laboratory Objectives:

3 1) To think scientifically: make observations, collect data, make appropriate interpretations or calculations, draw a conclusion, and finally become confident in using results for further interpretations in the experiment. 2) To learn to be critical of data and observations, be quantitative in measurements and exact with calculations, including the proper use of significant figures. 3) To develop good laboratory technique and to follow proper laboratory safety practices. 4) To communicate scientific findings through written and oral expression. Laboratory Class and Safety Rules: Basic safety rules will be explained during the first meeting and must be followed when working in the laboratory. Individual safety rules pertaining to specific labs will be identified in the lab handouts. You will not be allowed to work in the laboratory if you violate the rules. -compliance Penalties for Violations of Class Rules, Lab Safety Guidelines and Rules, Safety Goggles and Proper Lab Attire: 1. Students wearing improper attire will receive a verbal reprimand for the first violation; thereafter, students wearing improper attire will not be allowed to remain in the laboratory and must change into proper attire to be allowed into the laboratory. However, those students will not be granted extra time to complete experiments. 2. Tardiness will not be tolerated. If you are more than 10 minutes late you will not be allowed into the lab and will earn a zero (0) for that lab. Please be sure you understand this as it is not a negotiable rule. 3. Lab Rule-Safety Penalties If you violate any of the safety rules in lab, we may deduct up to 5 points for that lab. Academic Conduct All submitted work must be your original and independent work. Please refer to University of South Florida s policy on Academic honesty and the consequences of academic dishonesty in the USF catalog. Violations of this policy include among others, cheating on quizzes and the exam, reusing previously submitted work by you or others, and plagiarism. Assignments in violation of the policy will not receive credit and further violations can lead to more severe consequences. Attendance and Late Policy: It is very important that students attend every laboratory period. Knowledge and techniques learned in one lab may be used in the next lab. Lacking this knowledge and these

4 techniques may cause difficulty during the next lab period, in class and on quizzes and exams. Late pre-labs will not be accepted. Pre-lab reports will be collected at the beginning of the lab period. If you do not have a pre-lab report you will not be allowed to do that lab and will earn a zero (0) for that experiment. Post-lab reports will be due in class the period after you finish an experiment. If you do not turn in your lab report in class on the due date you may do so within 24 h for a 25% deduction (please note that the deduction is applied beginning at the end of the lab period when the report is due; please note also that you will not be allowed to work on lab reports during the lab period). Lab reports will not be accepted if more than 24 h late. No re-grades unless there is a calculation error. NO MAKE-UP LABS allowed due to lack of room availability. If you do not attend a lab period you will earn a zero (0) for that lab. This is non-negotiable. You will be allowed to drop your lowest lab grade to account for any unforeseen circumstances once. Lab Preparation: 1) Read the experiment/activity BEFORE coming to lab. 2) Make a serious attempt to understand the lab and its purpose before lab 3) Prepare for the experiment/activity by completing the pre-lab report (including questions/problems) 4) During pre-lab, be prepared to turn in: -lab report due at the beginning of class -lab quiz if not available online 5) Final Lab reports are due at the beginning of the next lab period except where noted in schedule or verbally 6) Every effort is made to grade and return labs within 7 working weekdays. 7) Grades will be posted and updated every 14 working days on BB 8) However students are responsible for calculating and keeping up with their own grade. 7) Please keep these papers organized to study for the exams and grade verification. GRADES: The philosophy on grading is that it should be easy to pass if the student is a responsible learner, but that an A should represent excellent work. Hence, it should be relatively easy to get a D. Learning is where the student constructs their own knowledge and meanings through active involvement in their learning not the instructor teaching to the test or lab. Almost anybody who has made it to college should be able to get a C, but it may take some work. Many students will or may earn a B, but it will take a lot of work for some. An A student usually represents someone who has engaged

5 in perfect class attendance, comes to class prepared, actively participates in class & outside of, attends tutoring when needed, has a superior understanding of the material, and uses effective learning/study techniques. The average student spends an average of about 8 10 hours per week on this course including time in class. do not wait until after you get a poor grade to get help. For those who are truly concerned we suggest you find a tutor, form a class study group, incorporate the Internet, and also make an office hour appointment The letter grade assignments will be based on an accumulation of points as follows: Lab reports: 100 points per report (30 points for pre-lab, 70 points for the post-lab report). Your pre-lab report must contain the following: Your name; title of the experiment; background in this section you must write a brief summary of the experiment you will be performing, the theory/ies behind the experiment, relevant graphs and calculations, etc.; procedure here you must include in detail your procedure (including a flow-chart if relevant), you should be able to use your pre-lab procedure to carry out your experiment. Your postlab report must be typed and include the following: name; title of experiment; very brief statement of goal/s; your results; discussion; conclusions. In addition, you must staple on to the typed report your notebook pages for that experiment. Quizzes: 15 points each. Lab Notebook. 50 points. At the end of the semester students will turn in their laboratory notebook. Your notebook will be checked for neatness, your attention to following proper procedure. Lab Practical Final Exam: 200 points. Cumulative final exam will cover laboratory procedures, equipment, chemicals, the concepts and results of experiments using scenario-type problems situations activities at lab stations. Please note: Absolutely no make-up exam. Your final letter grade will assigned based on what percentage of total points you accumulate as follows: 90% or above A 80% or above B 70% or above C 60% or above D
