Course Requirements Communication Students must have a current and usable VSU e-mail account through which they will send communications to and receive communications from their instructor. Students are expected to read their VSU e-mail daily. E-mails originating from Yahoo, Hotmail, Gmail or any other non-VSU account will not be read. Students should check electronic forms of course announcements daily. Electronic Access All experimental descriptions and procedures for each meeting period will be posted electronically. Access to computers and printers is required and locations and assistance in finding such access can be ascertained from The Learning Resource Center located in Harris Hall room 104. Course Activities   Students will participate in weekly experiments that are provided electronically on the course website. Students will come to lab on time and expect to participate for the full 2 hour period. Students will come to lab prepared by reading the lab and performing Pre-Lab Exercises. Students will maintain a laboratory notebook and produce laboratory reports.

Student Assessment Modes    Lab reports are collected the week following each experiment. The precise format of these reports is enumerated on the course Blackboard or website. Three lab exams will be administered the may consist of both practical and conceptual components. Pre-lab exercises are due at the beginning of each lab period and required in order for the student to participate in lab activities. The student performance is based on the successful completion of pre-lab exercises, active participation in the lab activities, diligence in performing experiments, ability to follow safety protocol and ability to maintain an orderly, clean and professional workspace.

A schedule of the experiments and dates of midterm are posted on the Blackboard or course website and will vary by semester. Weighting of Assessment Modes: 30% Lab reports 40% Lab Exams 30% Performance

Final grades will be computed as follows: (Average laboratory reports(drop lowest) x 0.30) + (Average lab exams (drop lowest) x 0.40) + (Average performance grade(drop one) x 0.30) = percent grade. The Grading scale is as follows.


A= B= C= D= F=

≥90-100% 89≤80% 79≤70% 69≤60% <60

Attendance and Exam Make-up Policies Students must attend during their scheduled lab period and recitation. There will be NO “makeup” labs or attending a lab at a different time other than scheduled. There will be NO “makeup” exams (midterm or final). Students who miss more than three laboratory sessions or fail to turn in four lab reports will not be allowed to return to lab. (see "University Policies." for addition information on the University attendance policy). All students will be allowed to drop all materials related to one missed laboratory period. This allowance will cover any unpredictable emergency. Students are still responsible for all testing materials that are related to the experiments that they may have missed. Students arriving more than 15 minutes late are counted absent and will not be allowed to enter the lab. The student will loose all credit for the lab. Homework Assignments Students are expected to complete a pre-lab assignment and a written report for each laboratory experience. The precise format required for these materials is described on the course website. Learning Outcomes, Activities and Evaluation Procedures OUTCOMES Students will learn…  The general procedures for conducting various elementary qualitative and quantitative experiments.  How to collect and organize experimental data.  The identity of typical chemistry laboratory equipment.  The procedures for operating common laboratory equipment.  The important safety precautions that should be practiced in the laboratory.  Proper and professional manner in which to present graphical data ACTIVITIES Students will …  participate in weekly experiments planned for each semester (see attachment)  prepare a laboratory plan or pre-lab  review all safety requirements  collect data through the use of laboratory devises and electronic instrumentation  record data and observations  perform data analysis  keep a professional notebook  provide professional reports


EVALUATION Evaluation will occur through the administration of assessment modes including: weekly quizzes, assessing overall preparation, and midterm and final exams combining both written and practical components testing comprehension. Evaluation modes include the graded laboratory notebook, reports and technique performance. Technique performance includes assessment of safety practice. Additional Information Students who are covered under the American Disabilities Act should privately inform the instructor of this fact so that appropriate instructional arrangements can be made. Appropriate Classroom Decorum Students are expected to behave in a manner that is conducive to the professional workplace; of primary importance is adhering to safety protocol. Safety will be discussed at length during the first laboratory period and a standard safety agreement must be signed in order to participate in weekly experiments (see attachment). If the student has any questions regarding safety at any time during the course, ask the primary instructor. The primary instructor will have specific rules for safety infractions. Academic Integrity The Student Academic Code is the prevailing policy regarding the academic standards and policies of the University. By accepting admission to Virginia State University, students are automatically subject to the provisions of the Student Academic Code, and are expected to uphold and support this Code without compromise or exception. The instructor may enumerate consequences of academic dishonestly that may include loss of credit for the work in question, loss of credit for the course, suspension or expulsion from the University.

TYPICAL LAB REPORT REQUIREMENTS (Will vary by instructor) PRE-LAB DIRECTIONS Obtain the experimental description from Blackboard, Website or handout for the lab. Inside the student notebook include the following in your pre-lab write-up before you attend your laboratory. A pen should always be used – never a pencil. PRE-LAB EXERCISE If required, usually completed on a separate printout and turned in with the notebook copy pages. NOTEBOOK PRE-LAB Top portion of note book. Experiment #, Title (Experiment/Subject), date, name, partner’s name, desk #, section #. OBJECTIVE: Explain the objective of the experiment using your own words in full sentence/paragraph format. CHEMICAL EQUATIONS - if any chemistry or dissolution process is relevant for the laboratory, those relevant equations should be shown. If multiple potential reactions are part of the lab, then a few representative equations should be shown. MATERIALS. List any materials that might be required. Do not list the obvious such as computer, notebook, pen etc. CHEMICALS AND PRECAUTIONS. List all Chemicals with concentrations and any potential dangers associated with those chemicals PROCEDURE. Draw a figure to represent any relevant set-up. In flow chart format, describe the procedure. Do not copy exactly as stated in the lab description. Do not copy your lab partner or any other student’s work. You must be able to complete the experimental procedure using only your notes. Handouts are not allowed. TURN IN STAPLED YELLOW COPIES OF THE ABOVE BEFORE LAB. START A NEW PAGE>>>> DATA TABLES: Prepare any data tables if needed neatly before lab so that you may record data carefully during lab. OBSERVATIONS: Record any relevant observations. POST LAB CALCULATIONS: Show all work if applicable in a separate section. Multiple calculations that are redundant need not be shown, just show one example calculation in those cases.


GRAPHS: According to the instructions given for each lab. Always in Excel format and in proper format with labeled axes and proper units. CONCLUSIONS: A conclusion section is a relevant discussion of the data collected in some greater context. The questions provided give and indication of the context a student should be able to identify with and should be answered completely, thoroughly and in full sentence paragraph format. Chemical equations if needed to draw conclusions or summarize data can be written in line-by-line form as they are not convenient in paragraph format. Any numerical answers should be written in the conclusion section even if the calculations are shown in the calculations section. Numbers without units are meaningless. The “prelab” and “postlab” combined together make up the student report.


GENERAL LAB RULES 1. Write the number of your desk drawer and your lock combination in your notebook. If you forget your lock combination, go to the stockroom and give your name, drawer number and student ID. 2. Do not put anything in your lab drawer except the equipment on the list provided to you. 3. Be sure to lock your drawer at the end of the lab period.
