You are going to design a clock to represent the different geologic eons throughout Earth's history.
- Research how long each eon lasted.
-Knowing that each hour of the clock is about 375 million years, determine how many hours each eon takes up on our 12-hour clock.
For example, if an eon took 750 million years, that would take up two hours of the clock.
-Within each eon, identify major events and the types of life that dominated the earth during that time. How you design your clock is up to you.
You can use a computer program to design your Clock of Eons or you can go old school and use poster board and markers.
