1. Use the first page at the beginning of the notebook for a table of contents.
2. Information for each experiment.....

   Number each page

   Title and date on each page

   Write a brief procedure at the beginning of each experiment. You will need to read it ahead of time.

   Show all raw data, labeled and with units and appropriate sig. figs.

   Show all calculations

   At the end of the experiment, do a summary of your results- at table may work.

   Make any notes or observations you think may assist you later in lab practicals.

3. Data obtained in any scientific experiment must be recorded directly, in ink, into a sewn-bound, serially numbered notebook. All calculations and unknown information must be included. You may use the notebook to keep notes and equations on each experiment.
4. All data must be entered into the notebook as it is obtained. DO NOT RECORD DATA IN ANY OTHER NOTEBOOK OR ON ANY LOOSE PIECES OF PAPER. Such actions will result in lost points for the notebook score!
5. Show calculations and all constants used.
6. Label all data precisely so that another person, (the laboratory instructors mother, for example), who is not familiar with your organization and idiosyncrasies can tell what you have done).
7. Keep data chronologically; you may skip pages to leave room for additional data provided you eventually void all pages which are not used.
8. Errors will undoubtedly occur. When they are detected, cross out the erroneous data with only one line as you may want to read it later. Refer to the page in your notebook where the correct results can be found.
9. Never remove a page from the notebook!
10. You must have your notebook to enter the lab! It might be best to leave it locked in your laboratory drawer. Your notebook will be graded during the laboratory. Occasionally you may be asked to turn in your laboratory notebook for grading, usually at the end of the week The notebook must be handed in at the end of the term for a final grading.
