Time Keeping: R U OK w/UT?

What would today's sunrise/sunset data look like in Universal Time (UT)? Would the photoperiods be any different? Explore this in today's data and Journal Page Week #6.

UT is the world standard of uniform time keeping, and you'll be using it next week for the Longitude Clues, so this is a good time to get familiar with it.

Journaling: How Sunlight Strikes the Earth

Draw an imaginary longitude line in both photos running from the North to the South Pole right down the middle of the United States (about 95 degrees west). In your Investigation Journal answer these questions:

In December, when does sunrise occur along the line you drew? (Pick two places north of, and two south of the equator.) Is sunrise occurring at the same time at all these locations along the line, or at different times?

In March, when does sunrise occur at the same locations along the line?

What's the difference between the months as to when sunrise occurs along the line? Why?
