Mr. Cesaire Solar Time Martin Van Buren High School
Aim: How do we determine the time at different cities? • Do Now: In your notes, explain why our local time is different in other parts of the world. • HW: Read and be familiar with pages 32-35 in your UPCO book.
Question- • Who can tell me the current time in Chicago, Illinois? • Miami, Florida? • Houston, Texas? • Los Angeles, California? • Honolulu, Hawaii? • London, England?
How do we determine the different times around the world? • If you have the following: • Green review book-read pages 13-14- solar time and clock time • Answer the following in your notes: • What is Greenwich Mean Time (GMT)? • How many degrees does the Earth rotate per hour? • How is this determined?
Solar time- the time of day at a specific longitude. • You can find your local time based on the current solar time at Greenwich, England (GMT). • Any location west of the Prime Meridian (GMT or UTC) is behind. • Any location east of the Prime Meridian (GMT or UTC) is ahead.
It takes the Earth to rotate once every 24 hours; or 360 degrees. • 360 degrees/24 hours=? • Now you try to find the times at different cities. • Lines of longitude are 15 degrees apart.
