Agenda

• Evolutionary Timelines• Continue Nye/Ham Debate

• Remember Thursday/Friday Room 3011 with the counselors

Timelines• Measure out 115cm of receipt paper• This will represent the approximate 4.6 billion

years Earth has been around (estimates are 4.54 billion +- 0.05 billion)

• Scale your timeline appropriately from Today to 4.6 billion years ago– Figure out how much each CM represents and

make a scale. Make a small mark every cm and larger mark every 10cm
