100%
*Final exam at the end of the course will cover all course material.
*At least a passing grade on lab marks must be achieved in order to write the final exam.
*You must pass both the lecture portion and the lab portion in order to pass the course.
*You must provide your own safety glasses. Prescription glasses are OK, but sunglasses are NOT. You must wear these safety glasses at all times while you are in the lab. You will not be allowed to carry out any experiments without safety glasses.
*Office hours are posted on the door. You can, however, drop by the office any time. Chem 120 is not an easy course and you might find that you will need help from time to time. You will not be wasting my time if you come for help. I’m here to help you learn.
Organization Of The Lab Report
Title of the experiment: State the title of the experiment you have just carried out.
Date: Write the date on which you did the experiment.
Name: Your name and lab partner’s name (if applicable)
Objective: State what you want to achieve by doing the experiment in one or two sentences. Be very brief and to the point.
Procedures: You can write the following: Please refer to Chem. 120 lab manual, 2007 Edition. pp. xx-xx. Record any changes to the given procedures.
Data: Organize any data, whether numerical or descriptive, in a neat table (or tables if applicable). Report such things as unknown numbers, concentrations of solutions, masses of reactants and products. Any relevant data recorded on a rough data sheet should be copied here. Do not forget to write chemical equations here.
Discussion and Calculations: In this part of the report, you will make sense out of the data you have obtained. If you obtain a product, calculate the percentage yield. Provide a physical description of your product. Show all the calculations you do, but there is no need to be repetitive. For example, if you perform 3 or 4 titrations using the same two solutions, then you only need to show the calculation for one trial. In cases where you have not obtained the results you were hoping for, provide a very brief explanation.
Conclusion: In no more than two sentences, state what you have achieved by doing the experiment.
Answers To Questions: In cases where questions are asked during or at end of experimental procedures, provide the answers here.
* Lab reports should be written in ink, including all calculations. The report does not have to be typed. If you are not using a computer to graph data, use graph paper. If your report does not follow the format given above, it may be deemed unacceptable and you may have to resubmit it. The new report will be considered late if it is not submitted on the same due date (see below).
* Lab reports are normally due one week after the assigned date for the experiment. You will be informed in advance if there are any changes to the due date.
* The report is marked out of 10. For every day the report is late, you lose 1 (one) mark.
* Make sure to staple the pages of your report together, including any rough data sheets. You lose 1 (one) mark if the pages of your report are not stapled together.
