Students and adults have a lot of trouble envisioning the history of the universe, from the Big Bang, 13.7 billion years ago, through the development of various structures in the cosmos and the evolution of life on Earth, to the present moment. In this activity, students will equate the full span of cosmic time with one calendar year, and see where different cosmic events fall on a 12-month time scale.
