It's About Time!



It’s New Year: time to think about time. How do we keep track of it? Does it really fly – or does it seem to stop at times? And is it really all relative?

  • Before there were clocks there were sundials. Find out how they work, and make your own: http://www.sundials.co.uk/
  • If you’ve seen New Year’s celebrations on TV, you probably know that the new year arrives earlier in Australian than in Hawaii. Why is that? Find out at  http://www.youtube.com/watch?v=widWLhIIbzs.  You can calculate the time difference between two cities using http://www.timeanddate.com/worldclock/converter.html
  • You can build a clock that runs on potatoes! Follow these videos to make your own: http://www.wikihow.com/Make-a-Potato-Clock
  • A year is calculated on the basis of one complete orbit around the sun. So your age would be different on other planets.  http://www.exploratorium.edu/ronh/age/ will calculate your birthday on other worlds (maybe a nice idea for parents).

CAREERS:
Many jobs depend on time: food and hospitality, transportation, medicine, education, sports – think of some others.  Some jobs have time as their central concern: watch makers, jewelers, astronomers and geologist (who have a different sense of time). Find out the details at:
