Dear fellow participants;

Here are our findings based on what we interpreted from the graphs we created from the data. We determined that the average daylight time increased the farther north a city was from the equator, with the exception of the cities in the southern hemisphere. We think the reason that the length of daylight time shortened the farther the city was away from the equator in the southern hemisphere is because that part of the earth is heading into winter in contrast to the northern hemisphere.

Our graph for the average daily temperature was a lot more confusing, because there was no clear-cut pattern like the average daylight minutes. Our line graph depicted sudden spikes up and down from a very general pattern that seemed to show the warmest temperatures were at the equator and slightly north, and then they gradually dropped generally the farther the latitudes were from the equator. We think that the pattern of temperatures was more erratic due to weather and the elevation above sea level of the cities.

We enjoyed participating in this project, and hope that more schools in the southern hemisphere will participate in the future. It will be interesting to do this project in the fall to compare and contrast the data. Thank you.
