General:

• Co-requisite: CHM 2046. If you are not currently enrolled in CHM 2046 on the Clearwater Campus of SPC, you will need to provide proof of enrollment elsewhere. If you withdraw or stop attending lecture, you will be withdrawn from this lab class.

Safety and Conduct in the Lab:

Safety: This is the number one priority in the lab. It is your responsibility to know and follow the rules and procedures at all times.

General Laboratory Safety Rules:

4 Appropriate dress must be worn to lab or you will not be allowed to stay for the lab work and you will receive an unexcused absence.

o Clothing must be appropriate for laboratory work. Clothing should not have loose sleeves.

o Shoes must cover your feet; no sandals, flip(flops, etc.

o All books, purses and other personal items must be stored out of the way so that they do not interfere with the safe conductance of the lab

o Handle all chemicals, glassware, burners, and other lab equipment appropriately and carefully.

o Food and drink may not be brought into or consumed in the lab.

o Read all chemical labels on containers THREE times: before you pick it up, while you have it in hand (as you are dispensing) and when you put it back down. Many mishaps can be avoided this way. Many chemical names are formulas sound and look alike. Never assume anything!

o Each student is responsible for cleaning up any spills or broken items.

o Each student is responsible for cleaning all used items and returning them to their appropriate place.

o All chemical waste must be disposed of in an appropriate manner as per instructor or lab instructions

o Each student is responsible for replacing all caps and making sure that chemicals do not become contaminated or spill.

o Each student is responsible for making sure that the sinks are free of debris and that the work area is clean before leaving.

Attendance Policy:

• 100% attendance is expected. You will be automatically withdrawn from lab class if you miss more than one lab period prior to the withdrawal date for this semester – October 20, 2016.

• No makeup exams or quizzes will be given so please do not miss one.

• Tardiness to lab is not acceptable. You must be in your seat prior to the beginning of lab. If you are late for a quiz, you may not have time to complete it. If you miss the discussion at the beginning of lab, you will miss important explanations.

• You may leave the lab upon completion of the work.

Supplies to be furnished by each student:

▪ Prior to the first lab experiment, each student must obtain and bring to the lab the items listed below.

Custom CHM 2046L Lab Manual (ISBN:9781285886428). Since this is a custom manual, you will need to purchase it from the campus bookstore

Notebook. 8 x 8 composition book is fine.

Safety goggles (Not glasses), approved for use in chemical laboratories, according to American National Standards Institute (ANSI) Z-87.1-1989. (available on the Clearwater Campus Bookstore and some home improvement stores).

TI-30Xa, TI-30XIIs or similar calculator. No engineering or graphing calculators are permitted, nor any calculator that has advanced functions, such as numerator/denominator display, answers that are put into correct number of significant figures, etc. Other brands are fine also, but make sure that they meet the guidelines.

• Cellular telephones, tablets or other web enabled devices are not allowed in the lab. These items must be stored while in the laboratory with ringers off. Students who have or take a cell phone out during a quiz or exam will be given a zero for that test.

REQUIRED ASSIGNMENTS:

• Read the material pertaining to each experiment prior to the scheduled lab. It is very important that before beginning each experiment you have a very clear idea of the purpose, procedure, materials used, and safety concerns for that experiment. If you find an experiment that contains material you have not yet covered in the lecture, you should look up the information in your lecture text.

• In your own words, write a detailed procedure for the lab in your lab notebook (before coming to lab). You will need to follow the procedure in your lab notebook (not in your lab manual) each day in lab, so write your procedure carefully! Leave room to record data, perform calculations, etc.

• As you go through the procedure in lab, take detailed notes in your notebook. Record masses/volumes used, colors/odors detected, reactions performed, etc. Your notebook is your only source for completing the lab successfully, and can also be used during the Final Exam as a resource.

• Quizzes: Quizzes will be given before every lab, focusing on the work done for the previous lab. The quizzes will be the only assessment of your abilities in the lab.

• Final: There will be a Final lab Test given. This test will be open notebook, so if you keep a good notebook throughout the semester you will be well prepared for this exam.

TESTING / GRADING POLICY:

Criteria for grading in-class and experimental procedures are as follows:

• Ability to follow directions, both written and oral.

• Ability to follow correct experimental procedures.

• Ability to follow safety rules and lab course policies.

• Dexterity in handling laboratory equipment properly and safely.

• Accuracy in calculations, experimental outcomes, use of critical thinking skills as documented in your lab reports, quizzes, and exams.

• Preparedness to perform the experiment.

The following weights will be given to exams, quizzes, and lab reports:

Lab Quizzes 70 %

Final Exam 30 %

Final grades will be assigned as follows:

90% and above A

80%-89.9% B

70%-79.9% C
