Procedure:
The purpose of this graph is to determine what the relationship is between a location’s latitude and the number of hours of daylight it receives. Make a
graph of the data.
1. Draw your x and y axes; Remember to use a ruler when drawing your x and y axes.
2. Label and number your axes:
a. Put the Time (months) on the x axis; label from Jan.  Dec.
b. Put Hours of Daylight on the y axis. Number from 0 to 24 hours, counting by 1’s (for example: 1, 2, 3, 4…etc); don’t skip lines.
3. Give your graph a title.
4. Plot the data for the four cities on your graph. Make a separate line for each city. Make sure you include a key so that you can tell the lines apart!
Analysis & Conclusions:
Answer these on a separate paper and staple it to your graph paper. Please don’t write on this page!
1. At what latitude is there the least amount of change from month to month in the number of daylight hours?
2. At what latitude is there the greatest amount of change from month to month in the number of daylight hours?
3. Rank the cities from least change to the most change in the number of daylight hours.
4. Rank the latitude from most change to the least change in the number of daylight hours.
5. Describe how latitude is related to the number of daylight hours the area receives.
6. Which city would likely be the hottest? Which city would likely be the coldest? Explain why.

Procedure:
The purpose of this graph is to determine what the relationship is between latitude and temperature. Make a graph of the data.
1. Draw your x and y axes; Remember to use a ruler when drawing your x and y axes.
2. Label and number your axes:
a. Put the Time (months) on the x axis; label from Jan.  Dec.
b. Put Temperature (°F) on the y axis. Number from -20 to 100 Fahrenheit, counting by 5’s (for example: -20, -15, -10, -5, 0, 5, 10…etc);
don’t skip lines as you number.
3. Give your graph a title.
4. Plot the data for the four cities on your graph. Make a separate line for each city. Make sure you include a key so that you can tell the lines apart!
Analysis & Conclusions:
Answer these on a separate paper and staple it to your graph paper. Please don’t write on this sheet!
1. At what latitude is there the least amount of change from month to month in the temperature?
2. At what latitude is there the greatest amount of change from month to month in the temperature?
3. Rank the cities from least change to the most change in the temperature.
4. Rank the latitude from most change to the least change in the temperature.
5. Describe how latitude is related to the monthly temperature of the area.
6. As you travel north from the equator during the month of February, do temperatures increase or decrease?
7. As you travel south from the North Pole during the month of February, do temperatures increase or decrease?
