The older students have been studying the history of life on Earth. To help them understand such a huge span of time, they created a proportional timeline. They measured the perimeter of the room and figured out a ratio of inches to years that they could use to plot different eras of history around the room. Additionally, they each studied different eras in the history of life, drew pictures to represent the era and wrote summaries describing the climate and the typical life during the era. For added fun (and rigor) they compared their research to the research the kids did on Monhegan Island. The kids from both islands met a few times over Skype to compare notes, make plans for improvement and share their work. The finished product is fabulous and very informative. Now they are using the timeline to help them understand extinction and how fossils help scientists to understand the past.
Bits and Pieces of the Timeline
This section of the timeline represents 505-409 million years ago!
This section of the timeline represents 248-145 million years ago!
This section of the timeline represents the present-141 million years ago! Modern humans are represented by a fraction of the tiny sliver of yellow on the far left of the timeline!
