Today was a key day for I Dig Brazil: when our teens start to put all the pieces together of their research, conversations with scientists, and virtual world fossil hunting to understand what happened 250 million years ago on earth. In short, why did 70% of all life die out during the Permian-Triassic Mass Extinction?
It was a good test to see how much they had retained from their weeks of work during I Dig Brazil, and how well they worked together as a group to solve the mystery.
In New York, our teens were given all of the data collected to date, in the form of worksheets that they had filled out, background info on the various rocks, plants and animal fossils they discovered, and maps of where they had found them. Their task was to assemble all the data together by period in time, to get a rough sense of what might have happened between the Permian and Triassic geologic periods.
They decided to divide up the investigation by fossil type, with one person taking rocks, another plants and the others animal fossils, and filling in the data on the different time periods. This was pretty efficient, and much of the information was completed by the time we got to the discussion portion of the workshop.
