Examining Daylight Hours Across the Globe
Tonight’s assignment is to explore the following flash application available at this link here. Our goal is to analyze the graph and how the hours of daylight change over the course of year at various latitudes on Earth. Answer the following questions in complete paragraphs.
1) Examine the daylight hours over the course of the year for the town of Reading. Use your research from HW last week to determine the latitude of Reading and then adjust the bar to that degree latitude. When is the longest day of the year? The shortest? What days does Reading receive 12 hours of daylight? What is the most amount of sunlight Reading receives? The least? Does this graph agree with the data you collected in class?
2) At what degree latitude do people begin to experience 24 hours of daylight or night time? Why does this occur on our planet? What happens at the North Pole and South Pole (90 degrees North and South)
3) Adjust the latitude to at least two other latitudes. Make sure one is in the southern hemisphere. Analyzing their graphs write a conclusion stating how the hours of daylight change as someone travels North or South of the Equator.

The longest time that reading receives the most daylight is 14 hours during June and July. The shortest time is during December and January for only 8 hours. The time that reading receives 12 hours of daylight is September. This information does matcvh with the data from last weeks lesson.
To recieve 24 hours of daylight, you would have to go to the south or north pole. These two places get 24 hours of daylight because the eaeth is titled on our axis at a 23 1/2 degrees and because they earth has different seasons throughout the year.
If someone traveled north or south of the equator, the area that they are in would decrease in daylight hours because as you go away from the equator, you get closer to the poles which recieve less or more daylight hurs throughout the year.
