Manual: “General Chemistry Laboratory Experiments (Experimental Procedures for Chem 124 Honors)” by R.W. Kluiber, Edgardo Farinas and Somenath Mitra.
This laboratory course is designed to give chemistry laboratory learning and research experience for Honors students, students who expect to major in chemistry or a related discipline (physics, mathematics, etc.) and/or students with strong background and interest in science. Some experiments in the course are designed to provide students with practical experience and basic techniques in the chemistry laboratory. Others will introduce honors students to the field of biochemistry and biotechnology. Our goal is to provide a logical framework for training students in how to approach research problems and conduct and evaluate scientific research. These experiments provide extensive background on the principles underlying methods used in research, followed by experiments designed to illustrate those principles.
This course is required to be taken concurrently with Chem 126 Honors. Two days will be scheduled for each week with six sections. Students are allowed to switch among sections. This means that students have added freedom via a choice of attending lab and completing experiments at any section. The students must read the course manual and complete the pre-lab quiz (there are no prelab quizzes for Green Chemistry: Microwave Induced Reactions, Gel Filtration Chromatography, and Colorimetric Methods for Quantification of Proteins) prior to beginning each experiment. Instructions are in the lab manual and concepts are from the text and lecture of the Chem 126 Honors lecture course and your Chem I / II Text.
Lab hours for the Spring 2011 semester are as follows:
Tuesday: 11 AM – 2 PM; 2 PM – 5PM; 5PM – 8PM
Thursday: 11 AM – 2 PM; 2 PM – 5PM; 5PM – 8PM
• Attendance is mandatory. You must attend one section of lab each week.
• Students should sign the attendance sheet each week when arriving in lab.
• If there are 30 people working you will not be allowed to enter, for both logistical and safety reasons, until the next section begins. No lab session will run with more than 30 students.
• All experiments must be completed during the same lab period. In other words, you may not begin an experiment and complete it on the following day or any other time period.
• The last week of the semester will be reserved for students to make-up labs which were missed. At this time, students will be permitted to make-up two experiments only. (You will not be able to make up “Green Chemistry: Microwave Induced Reactions”, “Gel Filtration Chromatography” and “Colorimetric Methods for Quantification of Proteins” labs.)
• For each experiment (except for Green Chemistry: Microwave Induced Reactions, Gel Filtration Chromatography and Colorimetric Methods for Quantification of Proteins), students must pass a prelab quiz prior to beginning the experiment. Instructions for completing the web-based prelab quizzes will be given on a separate handout and on page iv of your lab manual.
• Students cannot begin an experiment until they have completed and passed the prelab quiz.
• The completed prelab quiz accounts for 10 % of each lab grade.
• A lab report will be handed in for each experiment. The report consists of the completed data sheet found in your lab manual, plus a separate page containing your calculations.
• A complete lab report including Title, Introduction, Materials and Methods, Results, and Discussion is required for three labs, Green Chemistry: Microwave Induced Reactions, Gel Filtration Chromatography and Colorimetric Methods for Quantification of Proteins.
• For most experiments, lab reports must be handed in immediately following completion of the lab. For these experiments, late lab reports will not be accepted. For the final 3 experiments of the semester and the three labs mentioned above, students will be given one week to complete the report. Any reports turned in late will lose 10 points per week.
Working in Groups
• Students may perform experiments alone or with one other person. Any students found working in a group larger than two will receive a zero for that lab grade.
• Students working in pairs must arrive at lab and begin the experiment at the same time. Both students must remain in lab until the experiment is completed and the lab reports have been handed in.
• Students working in pairs can perform the experiment together and work on calculations together, but each student much hand in a separate lab report, which includes data and calculations which are their own work.
• Grades for the class will be determined solely upon the grades received on lab reports. Your grade will be simply calculated from the average of your 11 lab report grades.
• Remember, the completion of the prelab quiz is a part of your lab report grade. Each quiz is worth 10 points out of the total 100 points for each lab report. Failure to complete prelab quizzes is likely to affect your overall grade significantly.
Laboratory Schedule for Spring 2011
Below is a tentative weekly schedule. I will try to stick to this schedule as closely as possible. Students will be consulted with to reach an agreement on any modifications or deviations from the syllabus throughout the course of the semester.
