The Cosmic Times is a series of curriculum materials that trace the history of our understanding of the universe during the past 100 years, from Einstein’s formulation of gravity to the discovery of dark energy. The instructional materials resemble the front page of a newspaper from that particular time in history in which the discovery was made. The language of the articles mimics that of the newspaper from its respective era.
“The Evidence is Clear” is a 5E lesson from Cosmic Times created by the Astrophysics Science Division at NASA Goddard Space Flight Center. In this lesson students examine statements about the Big Bang and Steady State Theories to try to better understand the nature of our universe and how it began. First students sort evidence statements into two piles; statements that based on direct evidence or statements that are an inference. After reading the “Origin of Everything” article in the 1955 Cosmic Times, found here: https://cosmictimes.gsfc.nasa.gov/teachers/guide/1955/downloads.html, students further sort the two piles of into support for the Big Bang Theory or the Steady State Theory. After the first sort of cards, students should reread the article to confirm their sort. From analyzing the evidence statements from the two theories, students will construct an explanation as to which which theory they determine has the most reliable evidence supporting it and why
