This morning we used our knowledge of how fossils are formed to answer the question, "Why are fossils of shark teeth so common, but the skeletons of sharks are not?" We learned about the great megalodon shark that went extinct millions of year ago, and then watched a short video on modern day sharks that inhabit the bottom of the oceans: https://www.youtube.com/watch?v=9TDuPJ1lZAs. Arianna also took a short fun quiz to identify which species of shark she was most like: https://kids.nationalgeographic.com/games/personality-quizzes/which-shark/.
