Cosmic Times Overview Guide
The Cosmic Times newspapers tell the history of our understanding of the changing Universe through student readings tracing the major discoveries in cosmology over the past century. Each poster resembles the front page of a newspaper from a particular time in this history, with articles about the various discoveries.
Here we give a brief overview of each of the Cosmic Times issues. We also list lesson plans that can either be used as an introduction to Cosmic Times as a whole or that are appropriate to be used with any of the posters. The other sections of the Teachers' Guide give background information about the articles in each Cosmic Times issue. In addtion, those pages list lesson plans designed specifically to accompany the science topics within that particular issue of Cosmic Times.
