\subsubsection*{Instructions for Experiments}

\begin{enumerate}

\item Read each experiment thoroughly before coming to lab.

\item Come prepared to ask questions.

\item Review the pertinent material in the Physics Lab Help-Ware 
software on the Apple computers before lab.

\item Work in groups of 2 or 3 whenever possible.

\item Discuss the procedures and analysis carefully with your group.

\item Think before doing.  Consider ways you can reduce errors and 
uncertainties.  If your percent difference comes out large go back and 
re-examine your measurements and calculations.

\item Take precautions for safety.  Also handle equipment carefully 
to prevent breakage.

\end{enumerate}

\subsubsection*{Instructions for Lab Write-ups}

\begin{enumerate}

\item Use pencil.

\item Don't forget to report units with your measurements.

\item Indicate the quantity and units on each axis of your graphs.  
Spread graphs out to cover as much of the page as is reasonable.

\item Show all calculations, including calculations of slopes of lines 
and calculations of percent differences.

\item Write a conclusion section for each lab summarizing what you 
learned.  In your conclusions indicate which special steps you took in the 
procedure to minimize errors.

\item Report uncertainties and percent errors honestly and carefully. 
Don't report 0\% difference.  Percent difference is meant to indicate the accuracy of your measurements
and there is \emph{always} some error or uncertainty, so don't record 0\% as your
difference; instead, if it first seems to be 0\%, use some other method to
estimate the error (by, for example, using the number of significant digits
to give an estimate of the error).

\item Make your drawings and explanations so clear that a layman 
could understand them (and so you can still understand them in three 
years).  Sketches should show the important aspects of the operation of the apparatus.

\item Please staple multipage write-ups.

\item Neatness counts.  Clarity of communication is very important.
