Lab Hours CHEM 1A: SCI 211 http://chem.aellumis.org Monday 2:00-4:50pm Wednesday 2:00-4:50pm

Course Description The laboratory provides the student with experience in applying the principles developed in General Chemistry I lecture. Quantitative experiments that illustrate the fundamental laws of chemistry are emphasized

Required Equipment:  Chemistry 1A laboratory textbook can be found online at http://www.chemistrylabmanual.com or purchased from the bookstore  Safety Goggles  Student Notebook  Scientific Calculator

Learning Outcomes  CSLO-1: Understand laboratory procedures, safety, scientific method, and lab notebook recording.  CSLO-2: Understand the concepts of random error, systematic error, precision and accuracy, and their relationship to significant figures.  CSLO-3: Master chemical laboratory techniques such as measurement, determination of density, pipetting, titration, and spectroscopy.  ISLO-2, Reasoning – Scientific and Quantitative: Students will locate, identify, collect, and organize data in order to analyze, interpret, or evaluate it using mathematical skills and/or the scientific method 1. Ground Rules:  You must be here on time, attendance at every class is mandatory unless told otherwise  You cannot use a part-time job or some other obligations as an excuse for not attending class on time or for staying the entire 3 hours  You must read through the experiment before class on the first day of the experiment  Missing two weeks of class is grounds for being dropped  If you miss a class, you can only make that experiment up if we are still set up for the experiment

2. Grade Assignment

Lab Write-ups & Prelabs (pre-labs 5%, reports 25%, post-lab 10%) 40% Lab Quizzes 20% Unknowns/ Lab Technique 20% Lab Final 20% Total 100% Lab write-ups/ Post-Labs: The write ups include experimental measurements/observations and calculations of experimental quantities. The post-labs are question that probe your understanding of the experiment. These are due in the class following the completion of that experiment.

Pre-labs: The prelaboratory assignment is designed to prepare you for the upcoming experiment making sure you understand what you are doing and what is needed to fulfill the experiment objectives. These are due at the beginning of the class on the day your class starts that experiment.

Lab quizzes : These are given first thing, in the class following the completion of the lab, and are based on the material of the previous lab. Their purpose is to encourage independent assimulation of the material as we go. (Keep a record of your answers in the pre-lab for the test in your laboratory notebook).

Unknowns: In the laboratory schedule certain have either a quantitative or qualitative unknown to elucidate, using techniques that you will learn in the class. These test your care to detail and your analytical skills, which are skills vital to an experimental chemist.

Lab technique: Lab technique is a synonym for careful experimental technique and adherence to lab safety procedures, (wearing safety goggles where closed toed shoes etc). I will during the course of the course observe your experimental technique on several occasions. I assess your attention to detail, to measure carefully, to use clean glassware, to remain calm and clear about the steps in the experiment, your attention to safety etc. Accidents, where avoidable will adversely affect your grade that day. One accident in itself will not be crippling to your overall grade.

Lab final: On the last day of class there will be a final based on the work during the lab portion of the chem. 1a course. It is an opportunity to reflect over the course and bring it once more into your awareness before moving on to other things. It is longer version of the lab quzzes given during the semester. It is mandatory and normalized to 20% of your overall grade

3. When to hand in work  The prelab assignment is due on the day that the experiment commences, it should be handed in to me at the beginning of class.  The report sheet on the experiment itself along with the post lab questions should be handed in at the beginning of class on the day that you start the new experiment. The dates of when experiments start and finish is given on the attached sheet.  The lab quiz is given at the beginning of the lab class on the day the new experiment is to be started.

4. Breakages Accidents do happen, it will probably happen to everyone. If you do break something tell the instructor, and fill in a breakages form (you will not be charged, it is so we can keep track of inventory) Fall 2016 Chemistry 1A Laboratory Schedule
