Ask people in different parts of the country this question and you will get different answers. Ask people where I am from, and the most common answer will be “Because God prefers UNC.” Others will say it is a reflection of the ocean. But then why is the ocean blue?

Before producing this infographic, have your students discuss why the sky is blue. Have each student produce a short hypothesis, share it in small groups, and discuss the merit behind each. Then share this infographic and see how close students came to the truth.
