Condition :   Good  
Principle :   Star Patterns  
Area of Study :  Astronomy   
Equipment :   Planetarium with fresh batteries.
Procedure :   The planetarium works well if you understand its limitations. Since it has a very low intensity light bulb the projected star patterns are very dim. Therefore this must be used in a very small room of approx. 9 ft diameter. One of the plastic blow up bubbles in the sixth floor lab would work for this but since these have a small student capacity we don't deem this worthwhile to do in lecture.
