Over the past five weeks, you have use the Stellarium planetarium software to plan an observation, examine a number of celestial objects, and test astronomical hypotheses for yourself. In a 1-2 page length paper in APA format, please reflect on the past work you have done and answer the following questions:
How did the previous laboratory exercises help you to understand the scientific method and how astronomy uses observations to test hypotheses and theories?
Which of the five activities did you find to be the most interesting or educational?
Did you find the Stellarium program easy or difficult to use? What would you recommend to the programmer of Stellarium to make any changes or add any additional features?
If you had to use Stellarium to devise your own new laboratory exercise, what aspect of the program would you use? What astronomical objects would you focus on?
