Discussion Questions Lab 1
- Demonstrate how to use a star map (using one of the maps
from the lab book). Describe how to locate in the sky the
brightest stars on the map closest to today's date and time.
- Explain to the class how your local horizon is determined,
using a the `Blue Planet'' globe in the lab room and a sheet of paper or
a book. Show what portion of the sky would be visible to you and what
would be ``below'' your horizon.

(latitude 30 deg. South , longitude 70.8 deg West ). Suppose you were

constellations move in the night sky from sundown to sunup. Where
would they rise and set? Describe their path across the sky during the
course of the night. Explain to the class why the stars and
constellations move this way.
- If you traveled south toward the equator from East Lansing, how would
you observe the star Polaris the move in the sky? If you were standing
on the equator, where in the sky would you look for Polaris? Explain
