2/20

This week, we discussed other pieces of evidence that support the theory of evolution. We talked about the fossil record, geologic time scale, plate tectonics, and vestigial structures. In our lab, students practiced using relative fossil dating techniques to find the estimated age of different fossils. They had to arrange "rock samples" in order, based on their fossil components. Students were also required to create a timeline of their fossil record after putting them into the correct order. We spent Friday reviewing for our evolution test, which we will take on Monday. The test and binder check will be included as some of our final grades of the second trimester. Next week, we will begin our discussion of classification.
