Global Sun Temperature Project
May
2002 - FINAL REPORTS
Ernest B. de Silva Elementary School, Hilo, Hawaii USA
On a world map, we plotted out the location of the participating schools, and their average daylight minutes for the 5 designated days. We could visibly see why certain parts of the world have more daylight minutes than others. From this, we were able to have a better understanding of how far the sites were from the Equator, and the number of daylight minutes each site received.

During the months of April and May, we noticed on the Global map, the participating schools below the Equator had LESS daylight minutes than the other participating schools above the Equator. For example, Australia had fewer daylight minutes than places above the Equator, such as the United States and Uzbekistan.
Some areas of the Earth receive more sunlight than other areas because the Earth is facing the Sun from a different angle. The Earth rotates on its axis and is tilted in its position to the Sun, so some areas of the Earth receive less daylight.

Some places above the Equator have more daylight minutes which makes it hotter, because in certain months, certain places face the Sun directly, and other place do not.

Usually the more daylight minutes in the day, the warmer the temperature. However, there are places in the world where the temperatures are warmer, but their latitudes were further away from the Equator. WHY?
There are a number of reasons why this is happening.
We think this is because the Earth is tilted when it revolves around the Sun, so when one part of the Earth is facing the Sun, more the other part is not as much. For example, the Northern Hemisphere (above the Equator) of the Earth is having summer, and the Southern Hemisphere (below the Equator) is having winter.

Another reason could be the weather conditions, such as when hot air and cold air up in the atmosphere mix, this changes the temperature. Also, where the place is located matters. For example, if you are on an island surrounded by ocean (large body of water), your temperatures are temperate. If you are in a place surrounded by large land masses, your temperature can change quickly.

Another reason could be Global Warming. This is where the ozone layer in the atmosphere is becoming thinner, and that makes it hotter on Earth. So this can change the temperature of the place.

In this project, we learned that our answers came from studying the data that we had. The more questions we asked, the more discussion we had. We found that we were changing our hypothesis often. Having to work together as a team made looking for answers to our questions easier.
