Rock Around the Clock: An Earth History Timeline (title provided or enhanced by cataloger)
This time line lays out Earth's history within a 24-hour time period, from Earth's formation out of stellar dust up to the last Ice Age. Elementary, middle and even high school students will be surprised to discover that the most familiar human history is not even on the time line because it took place in the final second. The time line illustrates that if earths history had unfolded on one single day, humans would not appear until just before midnight.
