Test 1 Comments.

The test will probably have some free response, multiple choice, and some numerical work.  You are expected to show work, and give units when needed, and make statements supporting your work. 

You should be able to understand the relation between speed, distance and time.   The bold or summary definitions in the chapters.  Astronomic units, calculate speed of the Earth or Moon in it's orbit.  Light time to a given planet.  Universal law of gravitation (lab).  Lunar phases, rise and set times, eclipses.  Ecliptic plane.  Relative size and distances.  North, South celestial poles.  Ecliptic.  Horizon, Meridian, Zenith, Altitude, latitude, longitude.  Angular distance, arc minutes, arc seconds.  Circumpolar.  Prime meridian.  Celestial sphere.  Zodiac.  Sidereal, Solar day/year/month.  Summer/Winter solstice, spring/fall equinox.  Reason for season, moon phases, precession.  Tilt of earth's axis, and moons orbit.  Lunar and Solar eclipse, nodes, umbra, penumbra,  partial eclipse, annular eclipse.  Retrograde motion. Stellar parallax.

This is not necessarily a full list, but gets you started.  Also make sure you review each of the worksheets and lecture tutorials as these contain important information.
