We watched this video together in class and took notes over the events that they mentioned. This video uses a football field as a great way to help you understand just how much time Earth has been around (scale of time) and how the important events Scientists have included on the geologic timescale have impacted the way the Earth looks now.

INSTRUCTIONS: 

If you were absent the day we did this, watch the video: https://youtu.be/M8V_glRW1hA

Take notes while you watch of the events they mention. 

After you have taken the notes, practice categorizing them into the three main categories we have learned that scientists use: 

1) Biological Events – major changes in live (aka evolution)

2) Geologic Events – things like climate change, volcanic eruptions, earthquakes, land forming

3) Extinction Events – time periods where 75% or more of all species on plant Earth were wiped out!
