PART I: LATITUDE AND LONGITUDE.

1)    Visit this website:  http://www.maptools.com/UsingLatLon/LatLon.html

2)    Define:

a.    LATITUDE:                                                                                

b.    LONGITUDE:                                                                              

3)    Draw ONE globe showing LATITUDE and ONE globe showing LONGITUDE. Label the PRIME MERIDIAN and the EQUATOR where appropriate.

 

 

LATITUDE. Using the website in (1), fill in the blanks of the following sentences:

a.    Lines of latitude measure _______________ position between the poles.

b.    The equator is defined as ­­____ degrees, the North Pole is _____ degrees __________, the South Pole is _____ degrees __________.

c.     Lines of latitude are all __________ to each other.

4)    LONGITUDE. Visit this website: http://geology.isu.edu/geostac/Field_Exercise/topomaps/grid_assign.htm

a.    Fill in the blanks of this sentence: The reference line of longitude (the _________ meridian) runs from the _______ pole to the _______ pole through ___________, England. Subsequent lines of longitude are measured from zero to ______ degrees east or west of the prime _____________.

b.    FACT: Longitude lines divide the earth into 360 equal slices. Each slice is ONE DEGREE.

 

Part II. GEOGRAPHIC COORDINATES.

5)    DEGREES.

a.    Using your existing knowledge, how many degrees are in a circle? ________ degrees.

b.    FACT: 1 degree = 60 minutes (1º = 60’)

c.     FACT: 1 minute = 60 seconds (1’ = 60”)

6)    GEOGRAPHIC COORDINATES. Using the website in (5), complete the following sentence:

a.    One of the most common coordinate systems in use is the Geographic Coordinate System, which uses __________ of latitude and _____________ to describe a ____________ on the earth’s surface.

 

7)    What are the geographic coordinates of Pio Pico Middle School?

a.    Visit this website: http://terraserver.microsoft.com/

b.    On the left-hand side of this website, type in the address of Pio Pico Middle School. Street: 1512 S. Arlington, City: Los Angeles, State: CA.

c.     You should now see something like this:

d.    Click on the first link: “Urban Areas 3/29/2004”

e.    Voila! Here is an AERIAL PHOTOGRAPH. You will see a red dot which locates Pio Pico’s address that you entered. This red dot is right in the middle of a street! What is the name of this street? __________________________

f.      On what date (mm/dd/yyyy) was this aerial photograph taken? ___/___/______

g.    Do you see our school? Click on the North-East corner (upper right-hand side) of this aerial photograph. Look for our school’s four-square lines! Do you see them?

h.    Can you find our classroom (B-6)? Print out the image that you find! Only ONE print-out is necessary. Write your name on it and attach it to this worksheet. Put a circle around room B-6.

 

Longitude	Latitude

i.       Find the latitude and longitude of Pio Pico. It is located on the left-hand side of this page. The numbers should look something like this:

j.      LATITUDE OF PIO PICO: ____________

k.     LONGITUDE OF PIO PICO: _____________

8)    CONVERSION. The geographic coordinates of Pio Pico that you recorded are in a format called “decimal degrees” (which makes sense because there are decimal points in the numbers –-118.3166, 34.04655.) We will now CONVERT these numbers to a format called “Degrees, Minutes, and Seconds.”

a.    Visit this website: http://www.fcc.gov/mb/audio/bickel/DDDMMSS-decimal.html

b.    Scroll down to the pink box labeled “Convert Decimal Degrees to Degrees, Minutes, Seconds.” Enter your Latitude and Longitude that you found in (8i). It should look like this:

Convert Decimal Degrees to Degrees, Minutes, Seconds:

Latitude       Longitude

     

c.     Click the “Enter Decimal Degrees” button. You will see a blue box on the left side of the page labeled “Results.” In this box are your geographic coordinates expressed in “Degrees, Minutes, and Seconds” (DMS). It should look like this: Equivalent Coordinates in Degrees Minutes Seconds

d.    Record YOUR Latitude and Longitude here:

e.    LATITUDE in DMS: ________________

f.      LONGITUDE in DMS: _________________

g.    Fact: The symbol for degree is º. The symbol for minute is ‘. The symbol for second is “.

h.    YOU DID IT! Give yourself a pat on the back.

Part III: SOLAR SYSTEM

9)          Where are we in the SOLAR SYSTEM right now?? Visit this website: http://www.fourmilab.to/cgi-bin/uncgi/Solar/

10)     Scroll down beneath the image at the top of the screen. Fill in the following settings:

a.    TIME: NOW

b.    SHOW: IMAGES (not ICONS)

c.     DISPLAY: INNER SYSTEM

d.    SIZE: 400

e.    ORBITS: REAL

f.      LAT: 34 N

g.    LON: 118 W

h.    LEAVE ALL OF THE OTHER SETTING UNCHANGED.

i.       Now, CLICK the “UPDATE” button.

j.      What do you see? Print this page out (page ONE with the image only please) and write your name on it. Label Mercury, Venus, Earth and Mars.

k.     Now change DISPLAY from INNER SYSTEM to FULL SYSTEM. Click “UPDATE” button again. What do you see? The orbits of two planets are crossing. The names of these planets are _______________ and _____________. (Do not print this image out. Just print the image of the “INNER SYSTEM”.)
