Earth Science

HOMEWORK-DUE FRIDAY NOV THE 30th

Because everyone wants to measure their day with the sun being at its highest point at midday, scientists came up with the idea to divide the earth into different time zones. There are 24 hours in a day, so there are 24 time zones. The time is the same everywhere within one time zone, but different to all the other time zones. When you move from one time zone to the next one, you change your watch by one hour. If you are traveling in an easterly direction you move your watch one hour forwards, if you are moving in a westerly direction you move it one hour backwards.

Example:

·  New York is west of London, and they are separated by 5 time zones.

·  This means that when it is midday in New York it is 5 pm in London.

·  When it is midday in London it is 7 am in New York. 

You can try this yourself, first read the instructions:

·  Note the time on the clock. This is the time in London.

·  In the right-hand box, select USA/Eastern USA.

·  Watch how the bar moves to the left and the red spot shows -GMT 05:00

·  Notice how the time has changed on the clock. It shows 5 hours earlier.

GO ON THIS WEB SITE AND LOOK FOR THE TIME IN ALASKA AND BUENOS AIRES- ARGENTINA, RECORD THE TIME ON YOUR BINDER AND EXPLAIN WHAT YOU DID AND HOW THE TIME CHANGES FROM ONE PLACE TO ANOTHER.
