1 Where in the world is …? Unit 1 Lesson 2
2 In the index, there are 2 types of entry Nigeria 51 B4 Page
3 Try these If Nigeria is B4 What is Zambia? Where is Sudan MOSTLY? Egypt mostly? Name 2 countries in A5 A B C D
4 What about places? In Nigeria, is Abuja In the index for page 51 it would be Abuja50B49 10N7 11E B4 tells you which square The remaining pieces of information tell you exactly where in B4 it is 9 10N tells you the latitude 7 11E tells you the longitude
7 Lines Longitude lines run north and south. Latitude lines run east and west. The lines measure distances in degrees. Latitude Longitude
8 Where is 0 degree? The equator is 0 degree latitude. It is an imaginary belt that runs halfway point between the North Pole and the South Pole. Equator
9 Where is 0 degree? The prime meridian is 0 degrees longitude. This imaginary line runs through the United Kingdom, France, Spain, western Africa, and Antarctica. PRIMEPRIME MERIDIANMERIDIAN
10 Just to be awkward …. While for graphs, the coordinates is along the corridor and up the stairs For maps it is the other way round x steps y steps (x, y) _0N_0N __ 0 E _ 0 N _ 0 E
11 Like this It is on the 40 0 N And it is on E It is written as 40 0 N E E N
12 Starting on the LHS of the page …
13 But what if the place is not on a line? What you have been measuring is degrees Each degrees (believe it or not) has 60 minutes in it To get exact locations, you simply guess!! Lets look at one
14 Paris is between 40 0 and 50 0 N I would guess about 48 0 N between 0 0 and 10 0 E Say 2 0 E Your atlas says Paris is 48 52N 2 20E Not bad. And I didnt cheat!
15 Where am I thinking of? 53N 13E? 40N 34E? 41N 4W? 60N 11E? 56N 38E? 65N 21W? 60N 25E? 44N 8E? 40 N 50 N 60 N 20W 10W 0 10E 20E 30E 40E 50E
16 HOMEWORK Home work is a puzzle
17 Your Mission Crack the code to find out where the thieves are taking the loot. Briefing Crafty robbers broke into the Royal Geographical Society in London and stole armfuls of priceless maps. Finding them would be hopeless, except that they dropped a scrap of paper with some odd scribbles on it. At the top is a rhyme that seems to be an instruction from the thieves' boss: First letters from each place-name read. Spell out the town and come with speed.
18 Your Mission But the note doesn't mention any places! All you see are weird combinations of letters and numbers. Luckily, a sharp-eyed geographer peers over your shoulder and says, "Coordinates. How fascinating!" She refreshes your memory on latitude and longitude, those imaginary lines that help us locate places. The numbers, you realize, are the coordinates for cities all over the planet. (1) Find those places in an atlas or on a map. (2) As you find each place, write its name next to the coordinates. (3) Circle the first letter of each name. (4) Read the letters from top to bottom, and they should spell the name of a city. Now you know where to nab those cartographic crooks.
19 This means that is nearly 37 0 The thieves who broke into the Royal Geographical Society left behind this code. (As a bonus clue, weve added the number of letters in each citys name.)
20 Lets do S E is the atlas link Click on the page here and …..
21 Oceania S E Click on the page here and …..
22 New Zealand S E 8 letters – so we have a choice. Its close but which? Hint: the one your are after is usually in BOLD
