Time Zones

Today in class we finished the last part of the longitude power point; here are some things I recorded

• Are known as Meridians
• Farthest apart at the equator and meets at the poles

Then after that we started learning about time zones, and everyone was really confused. When we all saw the timezone map we debated about whether we should just make the world one time zone, keep it at 24 confusing areas, or even add more!!! While looking at the map the class observed how certain places only had one whole timezone, even though they were in different ones and how that counties government could decide what timezone they are in. For example, North Korea has 30 minutes increments instead of hour long ones. Here are some notes I took:

TIME ZONE - a region of the globe that observes a uniform standard time for legal, commercial, and social purposes; tend to follow boundaries of counties

• Earth is a sphere divided into 360 degrees of longitude
• Divide 360 by 24 time zones (one for each hour of the day)
• Each band of longitude is 15 degrees
