About Mr. Hudsons 8th Grade

• We are located in Milton, Delaware in the United
  States of America (38.5 degrees N, 75.2 degrees
  W). Our subject area is Earth Science. We are
  proud to be a part of Mariner Middle School. We
  are grateful to work on this research project.

Working on the Project

• The first thing we had to do is go outside in
  the shade and hold the thermometer at eye level,
  during the week of November 8-12, 2004 to measure
  the temperature. During the project we had to
  create two graphs by getting the information off
  of the Global Sun Temperature Project website. We
  created the graphs by using Microsoft Excel. Then
  we had to use the information from the graphs to
  answer two questions. The questions were what is
  the relationship between latitude and daylight,
  and latitude and temperature. We calculated the
  number of minutes of sunlight per day by going on
  the website www.wunderground.com to find the
  sunrise and sunset times for Milton, Delaware.

Our Results

• During the week of November 8-12,
• our average length of day was 614 minutes.
• our average daily temperature between 1100 am
  and 100 pm was 10C.

Length of Daylight vs. Latitude

• The relationship between the length of daylight
  and latitude is that in the southern hemisphere,
  as latitude increases the amount daylight
  (minutes) goes up. In the northern hemisphere, as
  latitude increases the minutes of daylight
  decrease.

6
Temperature vs. Latitude

• The relationship between temperature and latitude
  is that in the southern hemisphere, as the
  latitude increases the temperature decreases. In
  the northern hemisphere, as the latitude
  increases the temperature decreases.

Conclusions

• Some areas of the earth receive more sunlight
  than others because of the earths tilting of its
  axis. Right now, in the southern hemisphere , the
  farther you are from the equator the longer the
  days are.
• The places that are closer to the equator are the
  warmest because they receive more direct sun rays
  than places at higher latitudes.
