Today in class we took our South America and Central America quiz. I think I did really well because I was studying a lot. I'm happy I checked over my answers because I had the United States spelled " United Stats " . After the quiz, we started talking about time zones, we learned that there are 24 of them because there are 24 hours in a day. Time zones usually aren't just straight lines on a map. In fact, they actually curve around countries like Greenland and China. We also learned that they are usually 15 degrees wide. At the end of class, we started to discuss if time zones were even important in my opinion I don't think their that important and I think we can have the same time around the world.
