What You Should See (and Do)
As the Sun sets in the west on the evening of the 20th, the shadow of the Earth and the Moon will rise in the east. At sunset, the Moon will be in the Earth's penumbra, but the eastern side will be very close to the umbra, and within a few minutes of moonrise, a noticeable "chip" should be taken out of the full moon by the much larger, circular shadow of the Earth. Over the next hour or so, the Moon will gradually move into the umbra, until it is completely covered by our shadow. During this time, the portion of the Moon in the penumbra will be so much brighter than the portion in the umbra that you may not even notice that part of the Moon; but once the entire Moon is in the umbra, the lack of any brightly lit part will make the reddish glow caused by sunlight streaming through the atmosphere of the Earth very noticeable.
For maximum credit, draw the Moon as often as you can see some change in its appearance, and use word descriptions to clarify the changes you observed (especially if your drawings aren't a particularly accurate rendering). During the partial phases of the eclipse (while the Moon is moving into or out of the umbra), you may see changes in just a few minutes; but during the total phase (while the entire Moon is in the umbra), it may take ten to twenty minutes to see any change in its appearance. As indicated above, you should start your observations at sunset; ideally, you will end them when the Moon has completely left the umbra, and is far enough from it that you can no longer tell that it is being eclipsed, at all (around 9:30 or 10).
Your observations should be similar in size and quality to those for the Moon Project, showing the appearance of the Moon, and its direction at the time of each observation. Outline drawings are adequate for standard credit, but if more detailed drawings allow you to show the progress and appearance of the eclipse more accurately, extra credit will be awarded (more detail can also be shown, and extra credit earned, by adding photographic observations to visual observations).
Turning in Your Report
As with all lab observations (in or out of class), your name should be at the top of your "report" (the page or pages containing your observations), and the date of the observations (February 20, in this case). If you do the observations in class on the 20th, you should turn it in before leaving for the evening. Otherwise, you should turn it in at the next lab class.
