Moon Activity

Moon Activity (due as part of Quiz 3)

Brief Overview of Activity: Over a period of at least three consecutive evenings, you will make careful observation of the Moon's changes in appearance and position.

Required Items: a notebook to take notes or make a sketch (bring your red flashlight), you may take digital photos if you wish.   

Number of Observations needed: 3

Timing of Observations: 3 consecutive nights, around (and after) sunset, a few days after the Moon is new. Your instructor will inform you what the appropriate viewing days are in the term.

Procedure:

Choose a location with a good view of the western horizon from which you can clearly observe the Sun at sunset. Since we will be timing our observations a few days after the Moon is new, the Moon should be visible in the sky at (and for a while after) sunset. It is important that you make all of your observations from the same location and at the same time. You may want to mark the location with a piece of tape to insure you are observing from the same location each time.

First measurement: This measurement is important. It will be used as a reference point for all future measurements. Arrive a little early and try to find a suitable reference object in the distance near the horizon. Look for a distinctive tree, building, rock formation, or other object. Pick something you will remember and be able to easily spot each time you come to observe. Mark the location and description of your reference object in your notebook.

For Each Observation: Make a note in your notebook about appearance of the Moon and its location in the sky. You may make a sketch if you wish. Note any changes from the previous day's observation. Be sure to note the location, date, and time of your observations.
