The Cosmic Times Gallery Walk and Cosmic Times Jigsaw lessons serve as extensions to the Cosmic Times suite of curriculum support materials. They are intended to provide an introduction to Cosmic Times as a whole, giving students the larger picture... (View More) of how our understanding of the universe has changed over the last century. During the Gallery Walk lesson, students peruse the Cosmic Times posters to answer open-ended questions. During the Jigsaw lesson, students work in cooperative teams to understand the primary scientific advances over the past century that have contributed to our current understanding of the universe.
