Sunrise, Sunset & Winter Equinox

Hypothesis: The amount of daylight should be less each day as we approach the winter equinox.

Procedure: For a two week period the exact time of sunrise and sunset for each day was noted. From this data the amount of daylight each day was calculated.

Observations: From the data it can be seen that there is about one minute less daylight each day for the period of time measured.
