Our astronomy experiments show how science explanations can be built from careful and systematic observations. We include observations of the night sky and demonstrations of the models which have been proposed to explain them. We also follow progress from the ideas of Copernicus to the predictions and explanations that followed Newton's theory of gravitation.
