East-West Constellation Movement,<br />
Activity 4-5<br />
Objective<br />
The student should be able to observe and discuss the general east to west movement<br />
of constellations.<br />
Background<br />
Constellation configurations do not actually move above us, but only appear to move<br />
due to the rotation of the earth and the gradual revolution of our planet around the<br />
sun.<br />
Procedure<br />
• Set the projector for 7 p.m. on a specified date and latitude. Identify any one of<br />
the constellations visible on that date. With the students, make note of the location<br />
of the constellation.<br />
• Now move the projector to the 8 p.m. setting and observe the changes. Continue<br />
the process for each hour (ex. 9:00 p.m., 10 p.m., etc.). Students should note<br />
the general east to west movement.<br />
• Select a specific time to observe. Set the projector for the first day of the month<br />
you are observing. Note the location of a selected constellation.<br />
• Next move the projector to the first of the following month, same time of night.<br />
Note location of the constellation. Continue this date movement for each of the<br />
12 months. Discuss the yearly motion and compare it to the nightly motion.
