Recently, in observations of the health of my lawn I have realized
            
 that most of my grass is brown, much of it is dead and what isn't dead is
            
 not growing well.  Although I was initially inclined to blame
            
 meteorological factors beyond my control, I have come to realize that my
            
 neighbor's lawn is green and tall. . .essentially thriving.  Because of the
            
 fact that weather over my neighbor's lawn is the same as that over mine, I
            
 have concluded that there is some other factor responsible for the
            
 difference in the quality of our lawns.
            
       Since our lawns are side by side, many of the variables that affect
            
 my lawn also affect his.  Things such as temperature, moisture and daylight
            
 hours are constant for both.  This has led me to believe that there is
            
 something my neighbor is doing to his lawn that leads to its far superior
            
       By careful observation of the habits of my neighbor in his lawn care
            
 regimen, I have noted two fundamental areas that differ from my own.  Every
            
 morning, my neighbor waters his grass with a sprinkler for half an hour.
            
 Additionally, by observation and conversation with my neighbor, I have
            
 discovered that he applies a complete application of fertilizer every month
            
 to his grass.  Since I do not do either of these things, and since these
            
 appear to be the only ways in which the care of his lawn differs from my
            
 own, I am led to believe that either, or both, of these factors have a role
            
 in the success of his grass growing.
            
       I hypothesize that I can increase my lawn's health (in terms of
            
 greenness, percentage live grass and grass height) by incorporating
            
 watering and fertilizer into my lawn care routine.  I further hypothesize
            
 that each independent variable considered separately (watering and
            
 fertilizer) will increase my lawn health, but maximum results will be
            
 obtained by using both methods together.
            
       Developing a concise hypothesis is important because, ...
