Notebooks will be collected and graded during the semester and at the end of the term. Notebooks are to be kept current. Do not bring the written handout material from the notes to the lab with you. Do not write data on the left hand page and then copy neatly on the right hand page. You should have your notebook sufficiently well organized that you have places on the right hand side to record all of the data in a neat and clearly legible fashion.
Notebooks are to be kept in ink.
The balances must be clean and have readings removed and the doors closed when you have finished a weighing. Hot materials should not be weighed on the balance. Reliable weights cannot be achieved. Do not weigh anything that has solvent on the outside of the container. Wet containers lose water rapidly and will not give accurate weights.
