Show how the length of day changes with latitude by plotting the following points. Use
the table below as a graph and place an X in the box where you want to plot a data
point. For example, if you find that a day is 10 hours long at 30? N latitude, represent this
data with an X in the box where 10 hours meets 30 degrees. (You may use a graphing
program like Excel if you prefer.) If you are able to print, connect the points.
