What I learned

         Today was a flood of information, that I am still trying funnel through my storm drains. We learned about the geological time scale. We ended up learning about eons, eras, periods, epochs. Things like the Cenozoic, Mesozoic, Paleozoic, and Precambrian Eras. We talked about how geology is a way to find out things about the time before humans. We talked about radioactive dating, and relative age dating. We talked about how these layers of the earth go from oldest to youngest, starting bottom to top. The reason this is important is because of the things in these layers, specifically fossils.

         We learned about how it started with Single cell organisms, then moved on to soft bodied animals, shelled animals, fish/insects, tres, amphibians, so on and so forth. We toured the museum, specifically the Klein Geology Lab. We looked at the Trilobites and compared them to modern day arthropods. We moved on to the ancient fish shown in the museum. We talked about how very primitive organisms moved on land to make amphibians. We talked about dinosaurs possibly evolving into birds. And mammals coming, with humans coming last.
