As we set out to learn how looking at the sun, the moon, the planets and some stars can lead to an accurate fix of our position on the Earth's surface, it is important for us to understand several systems of coordinates.  Let's begin by understanding the lines we often imagine are drawn on the Earth's surface, the parallels and meridians.

With this lesson, as with the others, you'll proceed through a number of activities.  The buttons on the left take you through those activities.  In this set of activities, you'll first

  1. read through the summary material on the topic,

  2. read relevant textbook sections,

  3. do some paper and pencil problems,

  4. report your results to the instructor or the group,

  5. converse with your classmates about the ideas, and

  6. review the summary material again.

You'll notice that there are two kinds of homework assignments on the chart table, which are generally pencil and paper exercises which you do on the chart table (or kitchen table), and on the desktop, which are discussion topics shared with the group by computer.
