Star Projector Training Worksheet

| Star Projector Operation | Anatomy |

Name: ____________
Date & Time completed: _________

Other students in your group:

Check each of the following items when completed:

• I have turned the Goto Star Projector on.
• I have turned the Goto Star Projector off.
• I have set the sky to just after sunset for the current date.
• I have parked the projector.
• I have set the star projector to the latitude of Shawnee (35°N).
• I promise to be a good steward of natural resources by turning any lamps off, or the entire the star projector off, when they are not in use.
• I understand the use of Fixed Stars:
  To prolong the life of the bulbs that project the fixed stars, always turn the fixed stars on slowly. Go from off to fully on in no less than two seconds. (Once they are fully on, turn them down 1/10th of a turn or so, which allows the magnitude-differences to become more apparent.) To turn them on suddenly, in one quick turn of the knob, risks blowing out the bulbs and shocks them with a surge of current that decreases their longevity.
• Starting with the star projector in a parked position, I have located the Winter Hexagon and brought it into view using diurnal motion.
• With room lights off, I have turned on every light and run every motion controlled by buttons or knobs on the vertical panel of the console.
• With room lights off, I have turned on every light controlled by buttons or knobs on the horizontal panel of the console.
• With room lights off, I have run every motion controlled by buttons or knobs on the horizontal panel of the console.
• With the Goto spotlights on, or by holding a flashlight upon the star projector, I have run every motion (in order to identify how the projector moves) and turned on every light (in order to identify the source components on the projector).
• I can identify on the star projector all the parts labelled on the diagram.
