Week 9

Week 9

We focused on a geological timeline during lab this week. First, we individually guessed when we thought the moon formed, when dinosaurs roamed the Earth, and when humans, animals, and plants were first on Earth. We then investigated just how old our galaxy and our Earth is. Then we used an Earthviewer simulation to answer the question of the geological timeline we then further explored when these events took place and broke up into groups to find out what really happened during their billion years.

We created a timeline of the earth moon and life. (Geological timeline) 

This is what happened during ours:

2.4 bil years ago oxygen on earth

2.2 bil years ago snow covering earth

3.4 bil years ago first evidence of life on earth
