|
| Laboratory Reports |
|
|
|
|
|
Laboratory reports should be neat and concise (3-4 pages, excluding graphs) based on the following format: |
|
|
|
|
Title: |
|
|
Introduction: A brief discussion of the topic and the lab's objectives. |
|
|
Materials and Methods: Keep it short, there is no need to repeat handout information. |
|
|
Results: Include tables of raw and/or transformed data; equations and graphs. |
|
|
Discussion: Think, check if results make sense; explain their significance and the associated physical process; integrate concepts from class; discuss assumptions and limitations. |
|
|
Literature Cited: List in alphabetical order literature you have consulted and mentioned in the report |
|
|
|
|
Use
your computer's word processor and spreadsheet software for your lab report. Lab reports are due at the beginning of the following lab session. Lab reports turned in late will not be graded! |
|
|
|
|
| Lab Quizzes |
|
|
|
|
|
In the beginning of each lab session there will be a small multiple choice quiz. |
|
|
| Handouts |
|
|
| Downloadable handouts with instructions will be posted in pdf-format approximately one week prior to the lab sessions. Paper copies will be available at the beginning of each session. |
