Summary: This week we were learning about the continental drift and it was a theory by Alfred wegner. He found this out by looking a fossils in one place and then the other and there were the same fossils in both places. He told other scientists about his discoveries but since he didn't have any proof no one believed him. After a few years he went on an expedition in Antarctica and then there was a blizzard. When the blizzard cleared some of his students found him but it was to late he was dead. 30 years later another scientist came up with plate tectonics and explained to other scientists that the Earth really did move and that Alfred Wegner was right.
SP6: Constructing explanations and designing solutions
The goal of science is the construction of theories that provide explanations about the natural world. A theory becomes accepted when it has multiple independent lines of empirical evidence and greater explanatory power.
