Students worked on the graph in groups; each group was responsible for three months.
Students calculated the number of daylight hours using information from http://aa.usno.navy.mil/data/docs/RS_OneYear.php and graphed each day in 5-minute intervals.
We found that our “longest” day has 15 hours and 50 minutes of sunlight while our “shortest” day has just 8 hours and 35 minutes.
______________________________________________________
Number of Daylight Hours from September 1 through March 31.
______________________________________________________
Number of Daylight Hours from April 1 through August 31. On April 1 there are about 12 hours and 55 minutes of daylight, on June 18, 15 hours and 50 minutes (whoo hoo), and on August 31, 12 hours and 55 minutes.
Note: The four sections of white resulted when a student was ill and did not complete his/her portion of the project. Question: Should the team do the work for the absent student to make a complete graph? Or Should the team hold every individual responsible for his/her part?

Hello Three Rivers Christian!
We are working hard on our graphs and will hopefully posting them next week! We are sorry for the internet snafus that made us so late to be working with you.
Our latitude is 34 degrees North longitutde 92 degrees West so our graph will look different.
We now have a project for you.
Since we are so farther south then ya'll, we can still see constellations that you can no longer view at 8 PM.
Go to http://www.fourmilab.ch/
Once you are on the webpage, clink on 'Astronomy' then go to 'your sky' and then put in your latitude and longitude for your area.
The major constellations we can see right now are Cassiopeia, Pegasus, Cygnet, Lyra, Cepheus, Ursa Major and Minor, Draco, the summer triangle, and the Pleades. Orion rises around 9:30 PM. You may also see the large comet that has been showing itself in the night sky for the last month, Find out the name of the comet and its size, it's really cool! Look at the Pleades then look directly to your left about 35 degrees. Do you see that fuzzy spot in the sky? It's the comet! (Honestly, it may be hard to see by now). Mars is also visible right now, it's just to the left of Orion. It is really bright and would be great to see in a telescope.
We will be downloading our sky chart as soon as we can figure out how to do it! Suggestions Cindy?
