Course Objective: Students will be able to complete a lab experiment in a safe manner using proper analytical techniques (specific goals are noted below). Students will be able to discuss and interpret their results in a lab report. Course Outline: CHEM 113 is a second-semester, one-credit introductory general chemistry laboratory course meant to complement the lecture course CHEM 112. The course builds on material learned in CHEM 111 with emphasis on quantitative analytical procedures. Essential material covered includes proper use of a laboratory notebook, writing of a formal laboratory report, use of the chemical literature, experimental design, interpretation of data using statistics, laboratory safety procedures, and an appreciation for what instruments can and cannot do. The course introduces laboratory experimentation in the context of a variety of specific topics, for example: chemical kinetics of a simple chemical reaction; volumetric analysis; acid-base equilibria and titrations; oxidation-reduction reactions and electrochemistry; separations using gas chromatography.

Prerequisite: Chem 111 Requirements or concurrent: Chem 112

Safety First!

Safety: Students are required to sign a safety contract. Failure to abide by the Safety Contracts that each student signed, will result in the student being dismissed from the lab and ultimately removed from the course.

· Turn off cell phones, beepers, mp3 players, and other distractive devices during lab

· No food or drinks allowed (lab is three hours long, please eat before you come to lab)

· Goggles and appropriate clothing required at all times (no skirts, shorts, or sandals)

Materials required:

· Laboratory Notebook with permanently numbered pages and carbon pages

· Scientific Calculator (capable of logarithms and exponential notation)

· Goggles according to OSHA regulations must be worn at all times unless instructor says otherwise

· A black or blue ballpoint pen with indelible ink for data recording in your lab notebook.

· USB flash drive or you must email data to yourself at end of each lab.

Attendance: University regulations state that a student should attend every scheduled class (Policies and Rules for Students section 42-27). Absence from class is unacceptable. If an absence occurs the student is responsible for finding out what material was missed due to the absence. As stated in the above mentioned Policies and Rules, "If an evaluative event will be missed due to an unavoidable absence, the student should contact the instructor as soon as the unavoidable absence is known to discuss ways to make up the work. An instructor might not consider an unavoidable absence legitimate if the student does not contact the instructor before the evaluative event."

Experiment Make-ups: Make-up labs will be made up at my convenience before the end of the semester. There are no scheduled make-up days. You will be given zeros for uncompleted labs.

Lab Report due dates: Lab report due dates will be announced in class. Enough time will be given to complete the lab report, therefore overdue lab reports will be graded with a 10% each day overdue. It is the student's responsibility in finding a way to turn in their lab report via directly the instructor in person or through email; a confirmation will be given when the report was received. In order for a make-up to be validated, the student must contact the instructor within 24 hours before or after the day of absence by email or by phone. If one is a Penn State Athlete and will miss a lab due to a sporting event, then the student must give a copy of their schedule to the instructor within the first two labs of the course.

Lab with partners: Each student will turn in an original lab report even if the lab was completed with a partner. Twin lab reports will each receive a zero and other corrective actions may occur up to the instructor’s discretion (i.e. copying word for word another person's typed lab report). Remember to include your name on all completed projects.

Class Cancellations: Lab will not meet if there is a two-hour snow delay for Penn State Altoona. Other cancellations will be posted Penn State Altoona’s Website, lab room door, or announced in class.

Quizzes/Preparation: You should read the handout prior to coming to lab and be prepared to start the laboratory experiment as soon as you come into lab .If students are not properly preparing for class before hand; quizzes will be given at the beginning of each lab period. If you are late and miss the quiz, then you will receive a zero for that quiz.

Lab Reports: (specific expectations will be given for each report):

Each experiment will require a formal typed lab report.

Grading: There is no curve for this course

Dropping the Course: Contact the Office of the Registrar.

Academic Integrity: The Campus Statement on Academic Integrity, adopted by the Altoona College Faculty Senate states: “Academic integrity is the pursuit of scholarly activity free from fraud and deception and is an educational objective of this institution. Academic dishonesty includes, but is not limited to cheating, plagiarism, fabrication of information or citations, facilitating acts of academic dishonesty by others, unauthorized prior possession of examinations, submitting work of another person or work previously used without informing the instructor, or tampering with the academic work of other students.” (Policies and Rules for Students Section 49-20 at www.aa.psu.edu/academic/integrity.htm). All incidents of cheating and plagiarism will result in 0 points awarded for that particular assignment or exam. Further action will be taken if warranted

Goals for Chem 113 Laboratory
