This week in science we learned about mostly about the theory of Pangaea that Alfred Wegener proposed, and how well he is know for the continental drift. His theory was that all the continents were once a huge super continent. Of course, people thought that he was out of his mind and crazy to think such a thing, with no strong evidence. About 30 year after Wegener died. They started going further into research on the super continent and was found out to be true. To demonstrate Wegener's theory, the class had to fit all the continents together using paper models of the continents. This week, we also studied the layers of the earth, and how many layers it consists of. We found out that there are 4 layers. The crust, mantle, outer core, and inner core. The mantle is the largest in thickness and has several layers inside it.
SP2: Developing and using models
I constructed a physical paper model of the continents that formed the super-continent, Pangaea.
This model helped better understand Wegener's theory of how the continents used to be one. He had to find several pieces of evidence to be proved right, and was struggling to find evidence on how it all fits together. We had to try to find a logical way that the continents would fit together, and follow the paths of how animals and plants traveled . This helped me have a visual of the process that Wegener had to go through, accept not as long and complicated because it was a model given to us on paper that we had to fit together in a logical way. People must of thought that he was a crazy man without proper evidence!
