This sheet of questions goes with the
packet handed out in class including information from
Star-Finding with a Planisphere by
Alan M. MacRobert and The Edmund Sky
Guide by Terence Dickinson and Sam Brown.
Answer the following questions based on the handout and your planisphere. Use
complete sentences in your answers: some answers will require
frequent returns to the text to figure out and you will need to
use more than one sentence in some cases.
A few ideas for class presentations for this material. Do these after students have wrestled with answering the questions using their planispheres and imaginations.
Use SkyViewCafé to simulate the motion of the sky showing circumpolar constellations, rising in the East and setting in the West. Also show stars in the South seeming to move from left to right.
Use SkyViewCafé and the overhead projector to show how the height (altitude) of Polaris changes with latitude. You can just use the arrows on the keyboard to change the latitude north and south. Also, change longitude at constant latitude to show that a planisphere good at 45° N is good anywhere on that latitude.
Use SkyViewCafé to show stars at the zenith at 22:00 on 3/21, 6/21, 9/21, and 12/21.
Stars farther away look dimmer due to the Inverse Square Law./
Define the following terms in your own words.
