What time is it there?
We think about time in many different ways. The main way many students access time is by looking at a clock and thinking, "How much longer is this class going to take?"
What do you know about time changes? If I look at the clock on the computer I'm typing on right now, it says 6:09 PM, but if I ask someone here what time it is, they will tell me it is 20:10.
What does that mean? What time is it here in Nova Scotia and why is it different from our time in Chicago?
Time has many intervals. Sometimes a second or even a part of a second has great importance. (Think about races.) Sometimes we count the hours, days, weeks or months and the seconds tick by without notice.
Tonight, at the beginning of this expedition, we talked about climate change, what it means and whether the efforts we make can change the course of Earth's systems and its components. In this discussion, years are irrelevant, hundreds of years, too. Geologists think in millions of years and the changes to the Earth as a system and its components (including us) over that amount of time.
What kinds of time are important to you? How do you measure them? Do you like to zoom in to a second or think in terms what Earth will look like long after we're gone?
