**Question:** Does a city's positions on the Earth affect the order of the seasons?

**Claim:** Yes. The position of city's on Earth does affect the order of the seasons. If the city is located in the south, it seems to start out the year with summer, then winter. For Cape Town, South Africa and Sidney, Australia they both start out with temperatures of 77 (Sidney) and 69.8 (Cape Town) degrees fahrenheit. The warm temperatures that they start out with mean that they have summer as their first season. Cities located in the north start out the year with winter. Cities like New York and London have temperature of 38.1 (New York) and 39 (London) degrees fahrenheit. These cold temperatures indicate that it is winter not summer.


 * Graph:** To display this data, I chose a line graph. I chose this graph because with a line graph you show data over a period of time. I am showing the change of temperature over the months in the north and south hemisphere, so the best graph to use was a line graph.


 * Statements:**

- Statement one is true but statement 2 is not. If the seasons are opposite in the southern and northern hemiphere, then the earth cannot be at two places at once if statement two was true. The second statement says that the earth is farther away from the sun in winter and closer to the sun in summer. If the earth was closer to the sun during summer here in NY, then both the southern and northern hemsphere will have to be closer to the sun. And if it was winter in NY, both southern and northern hemispheres will have to away from the sun. It is not possible for the earth to divide in half and be at two different places at once. The earth can only be in one place at a time.


 * Question:** How does the angle of the Earth affect temperature distrubution?


 * Hypothesis:** I predict that the angle of the earth will affect the temperature change.

media type="custom" key="12486914" The angle or tilt of the Earth affects the temperature distribution because of the way it faces the sun. When NY was facing toward the sun, it had about a 3 degree fahrenheit change over a period of 15 min. When it was away from the sun, it had about a 2 degree fahrenheit change over a period of 15 min. In our lab after 5 min, when NY was facing the sun it's temp. was 77 degrees fahrenheit. And when it was away from the sun, it was 76.2 degrees fahrenheit. At 10 min., the temps. were 76.7 (away) and 79.9 (toward) degrees fahrenheit. When it was away from the sun, NY's temp. was colder then when it was tilted toward the sun.
 * Claim:**


 * Questions:**
 * 1.**Earths tilts lead to warmer temp. during the summer we are facing towards the sun. When part of the earth is tilted towards the sun, places in that area are going to have more heat than the area that is facing away from the sun. There for if we are facing the sun, we will get more heat and warmth than other places that are experiencing winter.


 * 2.** If the earth was not tilted, seasonal patterns would be different. If the earth was not tilted then the sun would always be hitting the equator. Then the northern and southern hemisphere won't be getting any direct sunlight and they will always have the same season throughout the year.

- One advantage is that we can visually learn about our topic and see for ourselves how the seasons work. - One disadvantage is that we could set the model up wrong and get the wrong information out of them. For example, the sizes of the earth and the sun were not right. Really, the earth is a million times smaller than the sun.
