15 November 2009 How Cold Are the Dry Valleys?

After living in the Dry Valleys of Antarctica for more than three weeks I will admit that they are cold, but how cold are they? We set up a data logger on our front porch to take temperature, relative humidity, and dew point readings every 6 hours to see how cold it was outside. In the following activity students can use our actual data to graph the temperature readings for our first week and our last week to see how the temperatures changed by hour and by day.
