Hi everyone! We have completed graphing and analyzing the data and this is what we have found. First, we found that latitude affects amount of daylight, as we had expected. The schools that were closest to the south pole had the shortest amount of daylight minutes and the length of a day got longer as the location got closer to the north pole. The reason for this is that the earth is tilted 23.5 degrees on its axis, and right now the northern hemisphere is tilted toward the sun. Next, we found that latitude affects temperature. The schools that were closest to the equator had the warmest average temperatures, and generally temperatures decreased as distance from the equator increased. While we had expected this, there was something we saw that we hadn't anticipated. We noticed that the daylight graph formed a straighter, more uniform line than the temperature graph. In other words, there was more variation in temperature with latitude than there was in amount of daylight. After discussing this in class we realized that while latitude is the only factor that affects amount of daylight, it is not the only variable that affects temperature. Other factors that affect the temperature is altitude and whether the school is on the coast or inland. We believe this may have resulted in the range of temperatures reported. We enjoyed participating in this project and look forward to reading the reports from other schools.
