Scale Model of the History of the Universe


  1. Predict when, on a one-year calendar, each event would occur. (1 pt. each)
  2. Working with others, use the Internet to determine how long ago each event happened. Use reputable sources (NOT Wikipedia) and look for independent confirmation. Write 2 sources in events column for each event. (1 pt. each)
  3. As a group, calculate the placement of each event on a one-year calendar. If more than one event happens during one model “day,” calculate and include the time. (1 pt. each)
  4. Individually mark the events and dates on your calendar. (2 pt. each)
  5. Individually, write a short report on the reverse side of this paper. Neatness counts. (29 pts)            
  6. If “now” is 11:59:59 p.m. December 31, 2017
