Earth is very old, and it can be difficult to visualize where key events in the history of life occurred against this backdrop of "deep time." one common way to represent geologic time uses the analogy of a one-hour countdown timer. the timer starts from the top at earth's origin (4.6 billion years ago) and moves clockwise to the present, making one full circle. in this analogy, one hour represents 4.6 billion years, one minute represents roughly 76.67 million years, and one second represents roughly 1.28 million years. (open hint 1 for an explanation of how these calculations are done.)

1.0 billion years old
2.0 billion years old
2.3 billion years old
4.5 billion years old

On july 4, 1776, thomas jefferson wrote the declaration of independence. the declaration of independence can be compared to a break up letter because jefferson explained why america wanted its independence from king george iii. read pages 516-520 in your textbook to discover why america wanted to be an independent country. you will write your own break up letter from the colonies to king george iii. your letter needs to be at least 5-7 sentences, include the issues/events leading up to this breaking point, and why the founding fathers felt independence would be better. remember! this is a “breakup letter”, so channel your inner taylor swift and make it creative!
