Cardinal Directions, Activity 4-1<br />

The student should be able to identify the North Star and cardinal directions within<br />

the planetarium.<br />

Procedure<br />

• Set the projector for a particular date, time and latitude.<br />

• Have the student locate the Big Dipper (Ursa Major). Locate the two stars at the<br />

end of the cup. These are the pointer stars. (See diagram.)<br />

Note<br />

If you are observing from a latitude near 30°, the Big Dipper will actually<br />

appear to dip below the northern horizon within a 24-hour period as it<br />

revolves around Polaris.<br />

• Follow an imaginary line connecting these two stars approximately 5 times the<br />

length between the two pointer stars. Polaris (North Star) will be the moderately<br />

bright star nearest to that line.<br />

• Have the students establish that quadrant as north. Have the students face north.<br />

Now explain that south will be behind them, east to the right and west to the left.
