Chem 1212 Lab Spring 2015 Instructor: Dr. Boatright Office: 2-118 Phone: 678-839-6028 email: dboatrig@westga.edu Office Hours: M 10-12, 2-4; T,R 9-9:30, 11-12, 2-4 W 9-12, 2-4 You must email me from your myUWG account or I will not respond. You will need a composition book to record your data and observations. Objectives: To apply the knowledge obtained in Chem 1212 lecture to problem solving in the laboratory. To develop good laboratory techniques; work safely; take data carefully; record relevant observation, and use time effectively. Tardiness / Missed Lab: Lab attendance is mandatory. Unexcused absences will result in a grade of zero. No makeup labs will be permitted. At the beginning of each laboratory we will discuss the laboratory. You must be present. Lateness will be penalized by deduction from the grade for that lab. Preparation for Each Lab: The labs will require preparation and careful work to complete in the allotted time. Read all laboratory material before coming to lab. It is important that you understand the theory and procedure of the experiment. The lab material will be posted on Course Den. You must print out lab material to bring to lab each week. During the lab: You must record all data and observations in your composition book. Use non-erasable ink, and never use white out. After the lab: Clean up the lab space, clean the glassware and put back in the drawer, and unplug hotplates. Reports: Laboratory reports are due before the next lab period. The reports are to be a minimum 200 words in length (discussion section), typed, and include the information requested in the lab material. Late reports will incur a 10% penalty for each day the report is late. Academic Misconduct: Honesty in reporting results is one of the essential characteristics of your laboratory work. Little of your grade depends on getting "good" quantitative results. You will be more severely penalized for misrepresenting results than for honestly reporting "poor" results. You may discuss the lab results with other groups, but copying lab reports (any part) shall be considered academic misconduct, and as a result, will be penalized to the fullest extent possible. Grades Lab Reports: 90% Instructor points: 10% points assigned based upon your efficiency, pre-lab preparation, cooperation, attitude, performance, and cleanliness. Learning Outcomes 1. To communicate chemistry with clarity. students’ abilities to: 2. Attainment of this learning outcome will be reflected by the Follow oral and written instructions to successfully complete laboratory assignments. Work with other students in assigned group projects. Write formal laboratory reports as chemists write. Use appropriate scientific tools and instruments to acquire data, process information, and communicate results.
