Physics 222 Syllabus Spring 2011

Instructor: Catherine L. Jahncke

Office: 225 Bewkes Phone: 229-5496

Text: None

Course overview: This sophomore level lab accompanies the Modern Physics Course. Some experiments are designed primarily to reinforce the material learned in the classroom. Others aim primarily to teach you laboratory skills.

Course requirements: The requirements for this course will consist of keeping a detailed lab notebook and writing two lab reports with drafts. Lab experiments will last two weeks. Before beginning each experiment you will find out some background information using your textbook, the library, or other resources. This information should be in your lab notebook when you come to lab with appropriate citations regarding your sources. You will not be able to begin the experiment until this information is in your notebook.

Formal Lab reports: You will need to turn in two formal lab reports. These should follow a formal lab write up procedure that will be handed out in class. For the first Formal lab report you may choose any experiment completed prior to Spring Break. For the second formal report you may choose any experiment completed by April 25. Each report will have two drafts. A half a letter grade will be deducted from your report grade for each day that the report is late.


Lab Notebook: Your lab notebook is an important part of this course. Each experiment that you conduct should be well documented in your notebook. In order to determine if you have been complete, a good question to ask yourself is "could someone repeat this experiment if they were given my lab notebook?" In this course your labnotebook will function as an informal lab report. You should think of the lab notebook as a journal of what you do in lab. It is best to record what you do as you go along. If you are setting up an experiment, make a sketch. If you are collecting data, explain how you are collecting it. Make a data table where you clearly define all of your variables. If you make a graph, put it in your notebook, and talk about what it means. If you make a calculation, include the equation and at least a sample calculation in your notebook. One way to think about your notebook is in terms of sections, but remember that it is more imporant to be detailed and inclusive than to be orderly.

Lab notebook sections
Introduction This contains background information obtained from written sources and should be accompanied by references. You will be expected to complete this section before you come to lab. You will be required to use at least one source other than your textbook and other than the internet. You may use another Modern Physics text.
Procedure This section describes your apparatus, how it is connected, and how your data is obtained. If you measure anything, you should describe how you measured it. Sketches are very useful here.
Data Any data you collect should be in your notebook in tables and in graphical format when possible. Whenever you measure something, you should think about the sources of uncertainty in the measurement and record them quantitative and qualitative.
Analysis What is the theory you use to analyze your data? What does your data tell you? What equations are you going to use? Where do they come from? What do the symbols mean? What is the uncertainty in your result?
Conclusions BRIEFLY summarize your experiment. State your primary results both quantitative and qualitative. Explain what you can conclude based on your results. How might your experiment be improved on?

Academic Honesty:

The student handbook states that "All students at St. Lawrence University are bound by honor to maintain the highest level of academic integrity. By virtue of membership in the St. Lawrence community, every student accepts the responsibility to know the rules of academic honesty, to abide by them at all times, and to encourage all others to do the same." You are responsible for your own work. In this class you will be expected to use reference materials to complete the introduction of your lab reports. The materials you use should be cited properly. You are expected to cite the lab instructions if you draw from them in your reports. You are also expected to create your own images using a digital camera or a drawing program where appropriate.
