Nightly Position of Constellations,<br />

Activity 5-4<br />

Objective<br />

The student should be able to describe the comparative positions of the circumpolar<br />

constellations in a given 24-hour period.<br />

Background<br />

The constellations, Ursa Major, Ursa Minor, Draco, Cassiopeia, and Cepheus, can<br />

easily be seen circling Polaris in a 24-hour period.<br />

Procedure<br />

• Using standard setup procedure with the Constellation Cylinder, locate the Big<br />

Dipper (Ursa Major) and Polaris. Show students how the Big Dipper appears<br />

to rotate around Polaris. You may do this by turning the projection cylinder one<br />

complete rotation.<br />

• Locate the other major circumpolar constellations and note the motion by turning<br />

the cylinder one complete rotation again.<br />

• Place the Starfield Cylinder on the projector and locate the Big Dipper and<br />

Polaris.<br />

• Give the students the worksheet of circles. Have them draw the position of the<br />

Big Dipper in the appropriate section of Circle #1.<br />

• Move the projection cylinder through 4 hours of the night time sky. You may or<br />

may not wish to identify the particular time. Have the students again draw the<br />

position of the Big Dipper in the appropriate section of Circle #2.<br />

• Continue this same procedure of 4 hour movements and drawing the Big Dipper<br />

in the rest of the sections of each circle. This will show the position of the Big Dipper<br />

through a 24-hour period. You may follow the same procedure for the other<br />

circumpolar constellations.<br />

Note<br />

It should be emphasized that in the real sky all of the positions would not be<br />

seen due to daylight hours.
