This article describes a series of demonstrations used to illustrate the difficulties that astronomers face when they observe astronomical objects from Earth. The concepts covered include atmospheric distortion, atmospheric absorption, and the effect of the inverse square law on the intensity of light. These demonstrations were presented using predict-observe-explain tasks that promote active engagement and highlight misconceptions.
