\subsubsection*{Instructions for Experiments}

\begin{enumerate}

\item Read each experiment thoroughly before coming to lab.  Quizzes 
are likely.

\item Come prepared to ask questions.

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

\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 Try to get as much of the analysis done during the lab period as 
you can.

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

\item Please staple multipage write-ups.

\item Neatness counts.
