History of the Universe Correct Answers Event How Long Ago? Big Bang Moon Protons/Neutrons Oceans Atoms Bacteria Stars Dinosaurs Galaxies Flowers Sun Humans Earth 14,000,000,000 This can be tricky for students. Some students will want to record how long ago the event happened (i.e.—14,000,000,000 ya) while others will want to record the answers as if the Big Bang were t=0 and the present day is t=14billion. Either way is fine, but you may want to have all students record their answers the same way. (c) 2015 S. Coates
