Adv Science

Summary:  During this week, I learned about biological classification. I also learned that a person named Linnaeus proposed the idea of classifying organisms. Another thing that I learned was that scientists use cladograms to organize and classify genera of different animals. SP1: Asking questions and defining problems.  I asked questions when we were completing our "Biological Classification Guided Notes" such as, "How distantly related are the archaeopteryx and a crocodile?" I asked more questions like, "Would crocodiles be the distant relatives of birds, since they both share a common ancestor?"  Image Link:  Bird Classifications

Summary:  During this week, I learned about scientists could use comparative analogy and homologous structure to compare two species to find out a common ancestor. I also learned that caimans had five toes and that a caiman hatches from an amniotic egg. Another thing that I learned this week was that an amniotic egg was an egg filled with fluid laid on land to help the developing embryo. SP1: Asking questions and defining problems.  I asked questions when we were completing our "Who is the Closest Relative to the T-rex?" such as, "Is it possible that the T-rex might have hair?" I asked more questions like, "What was the hide of a T-rex like? Was it rough, like an elephant's? Or scaly, like a crocodile?"  Image Link:  Different Skull Comparison
