\section{Indoor: visualizing the sky}

\subsection*{Materials} seasonal star chart or planisphere

\subsection*{Instructions}

Orient a planisphere or star chart for the current season with the
real cardinal directions (roughly). \textbf{Notice anything odd about
where N, S, E, and W are on the chart? How do you have to hold the
chart for the directions to match up with the real directions?}

Pick out a few of the brightest constellations and visualize being
outside and looking up to see them in the sky. \textbf{What direction
would you face? What landmarks would you see on the horizon? How high
up in the sky would the constellation appear (make a guess in
degrees)?}

Actually practice this indoors: face in the appropriate direction and
point up at the angle above the horizon where you expect the
constellation to appear. Now swing your arm to indicate the path of
the constellation through the sky over the course of the night. Show a
TA.

\section{Indoor: constellations in the Milky Way}

\subsection*{Materials} star chart or planisphere, large
Milky Way panorama

\subsection*{Instructions}

Now use your star chart or planisphere to pick out constellations in
the photographic panorama of the Milky Way. \textbf{Sketch whole Milky
Way with the constellations you have found in your lab notebook.}


\section{Computer: using planetarium software}

\subsection*{Materials}

computer with planetarium software, ``Seasonal Objects'' page from
Consolmagno and David, \textit{Turn Left At Orion} 2nd Edition: 1998,
, Cambridge University Press)

\subsection*{Instructions}

Make sure you each understand how to do the following:

\begin{enumerate}

\item Figure out how to set the time and viewing location. View the
  sky as it looks right now from our current location.

\item Find all of the current seasonal ``guideposts'' from the
    \textit{Turn Left at Orion} book.

\item \textbf{Find out what solar-system objects will be up tonight
    and where they are in the sky and record this in your lab
    notebook.} Think about going out on the roof at 8:00pm:
    \textbf{what direction would you face to see each planet that is
    up then, and how high up in the sky will it be?} 

\end{enumerate}
