Instructor:        Dr. Matthew Junker    

314 Boehm Science Center

Phone:  610-683-4199      Email:  junker@kutztown.edu

Office hours:   Tue. 3-4pm; Wed. 2-5pm; Fri. 11am-12pm

Lab time and location:  Monday, 2:00-5:00 pm, Boehm Science Center, room 207 (2nd floor)

Textbook:        Biochemistry Laboratory: Modern Theory and Techniques by Rodney Boyer,

                        Benjamin Cummings, 2006, ISBN: 0-8053-4613-9.

Notebook:        A bound notebook is required.  Spiral notebooks are acceptable.  Entries

                        must be made with ink (not pencil). 

Co-requisite:  CHM 312  Biochemistry II

 

Grading:          The total final score for this laboratory will be comprised by:

                                    average of all prelab assignments                    5%

                                    average notebook grade                                 10%

                                    average of all worksheets                               20%

                                    average of all reports and presentation          65%

            This total final score plus problem sets will count 20% towards your grade in

            Biochemistry II (see lecture syllabus).

 

Course structure:

The laboratory meets once a week for a 3 hour lab.  All glassware and equipment must be cleaned and stored by the end of each laboratory session.  Handouts with instructions for each lab will be distributed during a CHM 312 lecture during the preceding week.  Students are responsible for reading the handouts and assigned sections of the textbook before coming to lab.

 

Graded assignments:

1.  A written pre-lab is to be brought to each lab.  The pre-lab includes an Introduction and Experimental section with a flowchart.  The pre-lab format is described on page 7 (and Figure 1.4) in the Boyer textbook.  For the experimental section, you only need to make a flow chart.  The pre-lab can be hand-written.  (Pre-labs 5% of grade)

 

2.  For some labs, notebooks will be handed in at the end of the lab session.  They will be graded for organization, clarity, and content.  Proper notebook organization is covered in Boyer on pg. pg. 5-7.  (Notebooks 10% of grade)

 

3.  For some labs, the report that will be handed in will be in the form of “worksheets” with answers to specific questions.  These may be hand-written.  (20% of grade)

 

4.  For several labs, formal lab reports will be handed in.  The format of the reports (which will include the prelab) is described on pg. 7-8 of Boyer.  THE REPORTS MUST BE TYPED.  Due dates will be specified in the lab handouts (typically one week after the lab session).  (65% of grade)


Important notes on grading: 

1.  Getting experiments to work is always great, but the main emphasis of this course is learning the basic principles of experimental biochemistry, including how to trouble-shoot when things don’t “go right.”  Consequently, the grading of all reports and worksheets will be heavily weighted by demonstrated comprehension, as well as clarity, organization, and thoughtfulness. 

 

2.  The worksheets and reports will also be graded for the quality of writing: organization and logical flow, grammar and punctuation, and spelling.  Use complete sentences, proper paragraph construction, etc.

 

3.  You will work in teams of 2-3 people for many of the experiments.  However, all handed-in written assignments are to be your own work only, without collaboration with other students.  You may come to me for help (office hours, pre-arranged times, or email) as often as you like.

 

Course objectives:  Upon successful completion of this course, a student will be able to:

            - Use traditional and modern techniques of biochemistry

            - Explain the concepts on which the laboratory experiments are based

            - Write scientific reports, keep a laboratory notebook, and interpret laboratory data
