To Understand the Evolutionary Timescale Each person gets 92cm worth of paper Scale out 4.6 billion years on that paper (the approximate age of the Earth) – The 4.6 billion years should use up all 92 cm. Why are we asking you to use 92 cm HINT HINT… – Check with your teacher to see if your scale is appropriate

NEXT… Pick 10 MAJOR events in the history of the Earth (and life) – Do not focus on human events! You have 4.6 billion years to look at! Get this list approved Identify approximately when they occurred and place a sketch or small picture at the appropriate point. Label what happened
