2
Draw the cardinal and intermediate direction
S W NE NW SW SE Step “A” Draw the cardinal and intermediate direction
3
Step “B” Label the Lines of Latitude and Longitude as follows
NW SW SE 2° N Step “B” Label the Lines of Latitude and Longitude as follows 0°N/S 37 ° W 2° S 35° W 33 ° W
4
N E S W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N Step “C” Part 1 Create a scale bar EXACTLY 2” long and label as follows
5
How many degrees of latitude do you have between 2°N and 2°S?
NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N ?? Step “C” part 2 How many degrees of latitude do you have between 2°N and 2°S? 4 degrees
6
Now use the formula 1° = 69 miles and multiply 69 miles X 4°
Step “C” part 3 Now use the formula 1° = 69 miles and multiply 69 miles X 4° N E S W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N 69 X 4 = 276 miles This is the distance in miles between 2°N and 2°s
7
Now measure the distance in inches between 2°N and 2°S
Step “C” Part 4 Now measure the distance in inches between 2°N and 2°S N E S W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N 3 inches
8
Now divide the # of miles (276mi) by the # of inches (3”)
Step “C” Part 5 Now divide the # of miles (276mi) by the # of inches (3”) N E S W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N 276 / 3 = 92 miles SO… 1” is now equal to 92 Miles 92
9
Now divide the # of miles (276mi) by the # of inches (3”)
Step “C” Part 6 Now divide the # of miles (276mi) by the # of inches (3”) N E S W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N SO… if 1” = 92 then 2” is 184 miles (92 x 2) 184 mi 92
10
Conversion factor 1 mile=1.61 km
Step “C” Part 7 Convert to Kilometers N E S W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N Conversion factor 1 mile=1.61 km 92 mi X 1.61 km = 184 mi X 1.61 km = 148 148 KM 92 184 mi 296 km 296 KM
11
Step “D” Part 1 Calculation of Land Area
W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N 2” So.. Check your scale and find how many miles = 1 inch 4” 92 184 mi 148 296 km A = (2 x in?) X (4 x in?) Use the formula A= H x W A =(2 x 92) x (4 x 92) A=184 x 368 A= 67,712 sq mi
12
Step “D” Part 2 Calculation of Land Area
W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N 2 “ We want to figure out land area of just the “blue” area. So…. We estimate the blue area to be 95% of the Red square. So take 67,712 X .95 = 64,326 Sq. Mi. This is our actual land area. 4 “ 92 184 mi A= 67,712 sq mi 296 km 148
13
STEP “E” Population Density
W NE NW SW SE 37 ° W 35 ° W 33 ° W 2 ° S 0 ° N/S 2 ° N Just take the population of the island and divide in by your total land area Our population: 50,000 (just made it up) Our land area: 64,326 sq mi 92 184 mi 50,000 / 64,326 = .777 people per sq mile 296 km 148
14
Last STEP!!!! “F” States, Capital Cities, and Major Towns
Key State Capital Town
