CHM151L-General Chemistry I Syllabus

General Information:

Offered Fall, Spring, and Summer

1-hour of Laboratory Science credit

Instructors: All faculty with appointments in the chemistry department are eligible to supervise CHM151L sections.  All sections will utilize graduate, and/or undergraduate teaching assistants.

Course Prerequisites/Co-requisite:  CHM151

Distribution Block: If taken with CHM151, student can receive 5 hours of lab science credit.

Course Description:

CHM151L is the first semester of a 1-year sequence appropriate for pre-professional, science, and engineering majors. Principles, practices, and applications of contemporary laboratory chemistry will be addressed.  As a liberal studies course, CHM151L addresses the essential skills of scientific inquiry and quantitative reasoning, and the theme of environmental consciousness.  Students will have hands-on experience using the scientific method to describe, quantify, and solve problems of a chemical nature including several chemical processes that have direct impact on the environment (such as chemical reactivity and acid/base reactions).

Course Objectives: Students will be able to:

1. Demonstrate mastery of basic laboratory skills such as quantitative weighing, pipetting, dilution, and titration. (Scientific Inquiry)

2. Describe and demonstrate safe laboratory practice including risk assessment using hazard codes and MSDS. (Scientific Inquiry)

3. Utilize scientific notation, significant figures, and dimensional analysis to solve problems of chemical interest. (Quantitative Reasoning)

4. Predict, analyze and test experimentally the chemical and physical properties of matter. (Environmental Consciousness, Quantitative Reasoning, Scientific Inquiry)

5. Determine the numerical value of chemical concentrations and physical states with precision and accuracy. (Environmental Consciousness, Quantitative Reasoning)

6. Predict, analyze, and experimentally confirm the products of a chemical reaction including the use of net ionic equations. (Environmental Consciousness, Quantitative Reasoning, Scientific Inquiry)

Specific Skills: By the end of this lab you will be expected to be able to accurately use a volumetric pipet, pipettor, buret, volumetric flask, mohr pipet, balance, thermometer, and graduated cylinder in safely conducting titrations, dilutions, weighings, and other lab procedures. You must master using molecular mass, moles, molarity, percent-by-mass, density, m₁v₁=m₂v₂, unit cancellation, significant figures, and graphs.

Course Structure and Approach:

CHM151L will address chemistry -- the science of change, through hands-on laboratory exercises.  Using standard laboratory practice and equipment, students will measure, quantify and describe chemical properties, and identify chemical unknowns based on the results of their measurements.

Course Outline:

I.          Measurement of mass, volume, density, and fermentation (2 periods)

II.          Identification and Quantification of a metal chloride solution concentration (1-2 periods)

III.         The study of chemical reactivity (1-2 periods)

IV.        Energy and Light (1-2 periods)

V.         Identification of ions in salts (1-2 periods)

VI.        Acid-Base Titration (2-3 periods)

VII.       Extra Credit: Ideal Gas Law & Molar Mass, Household Product Titrations, Thermochemistry

Instruction and Evaluation Methods:

The primary instructional methods utilized in CHM151L are hands-on laboratory exercises. Demonstrations of laboratory methods and techniques will prepare the student to make independent observations of chemical phenomenon, and measurements of chemical properties.

Assessment of Outcomes:

A report of experimental observations and results will be completed for each of the six laboratory exercises.  Each lab is designed to address the content areas listed in the course outline.  Assessment of student learning outcomes is based on the correct identification of the composition or concentration of unknown materials through application of the scientific method (scientific inquiry, quantitative reasoning), and on the results of a hands-on practical laboratory examination (quantitative reasoning).  Both of these assessment tools test the student's competence with basic laboratory methods and techniques.

Textbook and Required/Optional Materials:

Required: General Chemistry I Laboratory Manual, CHM151L, for 2011-2012 by Hayden McNeil and indirectly vented goggles.  Both items are available in the NAU bookstore or University Text and Tool. The lab manual must be purchased before the second lab period. If there are no manuals in the textbook area ask for help at the textbook desk. You will also need a pen for recording data and pencil (calculations). Goggles are required starting with exp. 2.

Optional: lab coat or apron. More information on this course can be obtained at the Chemistry Instructional Laboratories Homepage at: http://jan.ucc.nau.edu/~jkn/Labs.html

Academic Dishonesty:

The Department of Chemistry and Biochemistry strictly enforces the University’s policy on academic dishonesty. Sanctions imposed for academic dishonesty include receiving partial or no credit on the item in question without the chance to improve the score, receiving an F for the course, or expulsion from the University. All work in this lab is done individually except for fermentation in exp. 1 and solar oven data in exp. 4 and then only raw data is shared, not calculated values. Using another student’s unknown, unknown #, observations, data, or results will be treated as academic dishonesty. In addition, if you repeat an experiment you must check out a new unknown from the prep stockroom (216). Using the same unknown number twice will be considered academic dishonesty. If other offenses are found in department or university records for other courses repeat cases of academic dishonesty will have serious consequences.

Course Grade:

The course grade is based on a total of 1000 points. 650 possible points are earned by the proper identification of unknowns and completion of experiments. 200 points are based on the results of a hands-on practical examination. The online Loncapa Pre-lab and Post-lab questions are worth 60 points and pre lab quizzes are worth 90 points. Points and grades will be assigned as follows:

	Pass/ Full Credit	Partial Credit	Repeat		Points off for late unknowns   or repeats:	Grade Assignment: Percent of Point	Final
Experiment	Points	Points	Points	Points		Total	Grade
1 –  Mass ,Volume, Density, and      Fermentation	100	30	20	10		90-100	A
2 –  ID&Conc. Salt Solution	100	50	20	10		80-89	B
3 –  Reactivity	100	50	20	10		70-79	C
4 –  Energy and Light	100	50	20	10		60-69	D
5A – ID Cations	50	25	10	5		<60	F
5B – ID Anions	50	25	10	5
6 –  Acid/Base Titration	150	80	30	10
Pre Lab Quizzes	90	6x15pts
Loncapa Points	60	Pre/post labs online
Lab Performance		Can lose or gain pts
Lab Practical	10-200
Total      =	1000

Experiment unknown report sheets will be graded pass (full credit), partial (about half credit), or repeat (about 20%).  Points will be assigned as noted above. A pass indicates that the experiment was done correctly and the techniques were mastered.  Partial credit indicates that there were small technique and/or calculation errors but no gross errors. If you have time, it would be a good idea to do experiments with partial credit over with a new unknown. A repeat indicates that major technique and/or calculation errors were made and the experiment should be repeated. Any experiment can be repeated with a new unknown from the lab prep stockroom (216) but late points will be deducted from the score. To repeat an experiment, analyze a new unknown checked out from the Lab Prep Stockroom (216). Use a new report sheet from rm 221 (chemistry computer lab) and be sure to staple any new calculation checks and the original unknown report sheet to it!  Report sheets turned in after deadline dates listed later in the syllabus will face a penalty for late work as noted in the table above. Grades will be posted on the web and updated weekly. To view your current grades on the web go to:    http://jan.ucc.nau.edu/~jkn/Labs.html

Extra Credit:

When you have passed all of the unknowns, you may try to earn extra credit points by doing one or more of the following experiments worth up to 20 points each: Bonus Titration, Molar Mass by Gas Law, and Thermochemistry experiments found on the web at the CHM151L homepage. Be sure to read the requirements carefully. You must do all the experimental work, calculations, and writing yourself – do not use another student’s work. The TA must sign and date the piece of paper used to collect the data during the period(s) it is collected. Attach this data sheet to mini report.

Pre and Post Lab Questions, Outlines of Experimental Procedures, and Other Requirements:

In order to safely complete an experiment with understanding, students must prepare in advance.  Students must therefore:

1. Read the experiment.

2. Outline the experimental procedures and do a safety risk assessment (on the start of the report sheet provided at the end of the experiment or on an attached paper if you need more room).

3. Do a web-based pre-lab on Loncapa before coming to lab to start that experiment (loncapa will be available on Friday, 1/27 by 4pm).

4. When an experiment is completed many of the calculations can be checked using calculation checks

5. Do any graphs where required

6. Copies of graphs and the calculation checks along with the experimental procedure outline must be stapled to the report sheet

7. All experimental data and questions must be completed for the experiment report sheet to be graded, otherwise it may be returned un-graded (Five points may be taken off for minor issues of missing or incorrect answers). Make a copy of stuff you turn in for a backup record.

8. Finally complete the Loncapa post-lab questions for the experiment. Loncapa and the calculation checks are online resources that will be introduced by your TA

9. Exact due dates are listed later in the syllabus (No exceptions to these deadlines)

Pre Lab Quizzes:  A quiz will be given at the start of the period when a new experiment is begun. The quiz will include questions similar to ones in the loncapa module including 3-4 pre-lab questions for the current experiment and 1-2 post lab questions for the previous experiment. Each quiz will be worth 15 points for each of the six experiments for a total of 90 points. Some questions for the final may come from quizzes. The web based loncapa module for an experiment should be completed before lab on the day you start an experiment. To work safely in lab, students must be prepared. There will be questions on the experiment risk assessment on the quiz including hazards of chemicals to be used. No makeup quizzes will be given.

Lab Performance: Proper lab technique, safety, and work station cleanup procedures are required in this lab. Poor technique such as using the balance or pipettors incorrectly or unsafe behavior such as not wearing goggles can result in the loss of 1-30 points per incident. Extra points may also be given for excellent lab performance above and beyond. You will be completing a contract on issues regarding lab performance. Please be aware of the following requirements:

• You are required to clean any used glassware and your work station areas at the end of every lab period. To clean glassware rinse with hot tap water several times and once with RO water in RO tub or from your wash bottle. Fill your wash bottle with RO water for this purpose and other uses. Don't use the RO water tap for rinsing glassware. This valve is not designed for this level of use. Use soap if needed. Always wash glassware before you put it away.
• If you break or lose any glassware or equipment you must replace it at the prep stockroom. Your workstation must be clean and complete at the end of each lab period for the next student or you will lose lab performance points.
• Store any solutions you prepare in the “Student Materials Drawer” for your section and workstation.
• Make sure chemicals are labeled with your name and workstation #, chemical name and concentration, and hazard code or hazard.
• Always check the calibration of a pipettor before using it!
• All data and observations must be recorded in pen while pencil can be used for calculated values.
• Show an example using unit cancellation (dimensional analysis) for each type of calculation you do.

Safety: Safety in the laboratory is of great concern to the chemistry department. You are expected to be familiar with and adhere to the chemistry department safety policy noted in the lab manual at all times while in the laboratory.  Be informed about the hazards of chemicals before you use them by doing a risk assessment for each experiment. Every chemical in the laboratory is labeled with a hazard code to assist in this process.  If you would like additional information, material safety data sheets (MSDS) for every chemical used in this lab are available for your reading:

· In your lab in the safety binder in the first glass window cabinet as you enter the lab.

· In room 212 on the left as you enter the room.

· For NAU MSDS go to the Regulatory Compliance’s website: http://www.research.nau.edu/compliance/orc/

            (Click on the MSDS icon in lower left).

· You will do a web based MSDS tutorial-quiz to become more familiar with using them. You must print the certificate indicating you have completed the tutorial and turn it in to your TA before you are allowed to do any labwork beyond experiment 1 and checkout an unknown packet. This website is another source of MSDS. The tutorial can be accessed on Instructional Labs Homepage by clicking on the “Safety Information” link and then on the “Quiz” link. There is much useful information on this site, such as MSDS information.

· You can also google the chemical name with MSDS and quickly find them.

There is a remote possibility that medical issues such as respiratory conditions, allergies, pregnancy, etc. may be aggravated by chemicals used in this lab. Please talk to your instructor and TA if you have any questions about taking this class with special medical conditions. Phones are located in the hallways for contacting campus security at 3-3000 in the event of an emergency or dial 523-3000 if you use a cell phone. You will also be expected to immediately clean up any small spills you make and clean your work area with a damp sponge and rinse out the sponge then wash your hands at the end of every lab period to avoid losing lab performance points. Always wear goggles after the 3rd lab period.

Lab Practical: The laboratory practical will be given during the next to last lab period and will take 90 minutes.  The practical must be taken in your regular lab section.  The practical is an experiment using many of the techniques covered in this course.  The lab practical instructions and practice problems found on last page of your lab manual will explain more about the lab practical (Answer to practice problem is posted on CHM151L web page). A help session will be given before the lab practical. The lab practical may also include questions covering any other material covered in this lab. Unit cancellation must be shown for all calculations.

Put extra stuff in the lost and found. Put goggles and any labeled solutions you prepared in the TA drawer for your section.
8. Wash your hands at the sink in exit area, and exit the lab.

After the experiment is completed:

9. Do any calculations when the experimental work is completed and printout any graphs or spreadsheets.
10. Complete any web based calculation checks to insure your calculations are correct and print copies.
11. Answer any post-lab questions on the report sheet and staple the experimental procedure outline, risk assessment, graphs, spreadsheets, calculation checks, or post-lab questions to the report sheet. (for repeats of unknowns staple this old work on back of the new report sheet).
12. Copy the key information from your report sheet into the blanks at the end of the experiment in the lab manual and/or make a copy of any work submitted. If your report sheet is lost and this information is not copied down you may have to repeat the experiment again! Do not remove this page from your lab manual as it serves as a data backup!

Turn in the report sheet to the TA for your lab section. They will check to make sure the report sheet is complete. Finally complete the loncapa post-lab questions before the deadlines noted in the syllabus.

Makeup Labs: You may attend another section of CHM151L to make up a missed lab if you have been sick or miss a lab with an institutional excuse. To attend another lab section you must get your regular TA's approval to attend a makeup lab:

1. Your normal lab TA will fill out a “Make up lab slip”.

2. Take this slip to the TA of the lab you wish to attend to complete the makeup work.

3. If there is enough space (less than 24 students) and equipment, you will be allowed to work in the lab at the instructor's or TA’s discretion.

4. The TA for the makeup lab will complete the slip and give it back to your regular TA.

5. This process can also be done by and exchange of emails.

 You may not attend make up labs if you fail to attend you normal lab section regularly.

*Syllabus or schedule subject to change at instructor’s/TA’s discretion and circumstances.
