In today's lesson we learned about the equator, Prime Meridian, Lines of longitude and latitude, directions, different types of compasses, legends, scales and time zones.
EQUATOR AND PRIME MERIDIAN
The equator is the line that the sun hits the most and splits the world in an imaginary two peices. The equator is 0 degrees Latitude. The prime Meridian is the line that divides the world into an imaginary 4 peices after the equator. The Prime Meridian is 0 degrees longitude.
LINES OF LATITUDE AND LONGITUDE
Lines of altitude and longitude is what helps people find where they are on this big planet earth. Lines of Latitude go from East to West. Lines of Longitude go from North to South. The prime Meridian is also a line of Longitude
DIFFERENT TYPES OF COMPASSES AND DIRECTIONS
There are 4 main directions, North, East, South and West. I know of 3 different types of compasses...The Rose compass, The regular compass and the one that has north east. The Compass rose is the one that shows at the corner of a map that sometimes doesn't show all the directions but it always shows North. The Regular and most common type of compass has every direction, N, E, S and W. The other compass that I don't know its name is the one that shows the intermediate directions and the Regular directions.
LEGENDS
Legends are small colored boxes with little symbols in them that are also on the map. They represent different things on the map such as Malls, Blocks, Strrets, Parks, etc.
That concludes todays lesson.

Map elements: In Janine's words
Mapping Elements
Today we learnt about the equator, prime meridian, latitude, and longitude. The equator is what circles the earth from east to west, it’s 0 degree latitude. The prime meridian is what circles the earth from north to south, it’s 0 degree longitude. Now you are probably wandering what’s latitude and longitude. Well latitude is imaginary lines that map makers made up to measure the earth’s length and find coordinates. Hemispheres are the four quarters of the world. There is the northwest hemisphere the northeast,the southwest hemisphere and southeast. That pretty much covers all of the basic mapping elements you need to know in grade six.
Mapping Paragraph by Shakaed
There are also Scales and Compass Rose on a map. Because maps are shrunken so many times compared to the real earth, there is a scale to show distances from one place to another. About 1 inch on map = 1 mile on Earth. A compass rose shows cardinal directions: North, East, South, West, and intermediate directions: Northeast, Northwest, Southeast, and Southwest. There are 24 time zones per day. Each place has a different time zone.

Map Elements
Today I will be talking about latitude, longitude, hemispheres, directions, time zones, scales and map legends.
Let's start with latitude and longitude. The world has imaginary lines that help you locate a specific place. The lines that go east to west are called latitude lines while the lines that go north to south are called longitude lines. These lines are measured in degrees. In the middle of the world going east to west is the equator which is 0 degrees latitude while the prime meridian which goes north to south is 0 degrees longitude as shown on this map below.
Now let's go to hemispheres (means half earth) So if you think about it, it should be two halves but you are meant to count the Equator as a line and the prime meridian as a line so you end up with four quarters the north, south, east and west.
Just about every map has a compass rose which tells you which way north is so you know in what direction everything is. Another thing you have to remember is that there are two different kinds of directions: Cardinal directions which are north, south, east and west, and Intermediate directions which are northeast, northwest, southeast and southwest.
Onto map legends now. A map legend is just like an instruction manual which tells you what kind of map it is, a scale (which I will tell you about later) and little diagrams that tell you what they mean on the map.
A Scale is a graph that shows you how long a specific distance is on the map.
Time zones are lines on the map that show you the difference in time between other places, for example; the difference between New York and Vancouver is that New York is always three hours ahead.

Lesson 1 on Mapping
Mapping
There are many different parts to mapping. These include latitude, longitude, hemispheres, directions, time zones, scales, map legends and the compass rose. I am not going to explain each one of these, just the ones we have learned so far in class.
My first topic is the difference between latitude and longitude. The earth is divided into lots of different lines, latitude and longitude. Longitude means lines running vertically and latitude means lines running horizontally. The way we measure these lines are in degrees. For example the equator (which is the main line of latitude) is zero degrees latitude which would make the prime meridian (which is the main line of longitude) zero degrees longitude.
Now we will talk about hemispheres. If you split the word hemisphere in half it means a half a circle, kind of like splitting a ball in half it gives you two halves. By using the equator and the prime meridian we can divide the world into four equal hemispheres: north, east, south and west. So in other words we are cutting the world into four.
Another huge part of mapping is using scales. When you look at a map it usually looks very small. Of course it is not the real size of the area you are looking at, it is just a scaled size. For example one inch can be equal to one mile (different maps have different scales).
Even though the last mapping item on my list was the compass rose, it is certainly not the least. Without the compass rose we would not be able to know which direction we are travelling in. The compass rose is split into two portions. There are the cardinal directions and the intermediate directions. The cardinal directions are north, east, south and west and the intermediate directions are northeast, northwest, southeast and southwest. The reader has now become an expert on four parts of mapping. I hope you have understood my careful explanations.

Latitude, Longitude, the Hemispheres, Directions, Time Zones, Scales, and much, more! Where to start? I think the beginning.
The earth is divided into lots of imaginary lines called longitude, and latitude. Longitude lines go from the North to the South, and latitude lines go from the East to West. What helps remember latitude is to think of the lateral pass given by football player (American). These lines are measured in degrees
In this picture we can roughly make out the lines of longitude and latitude.
Also in this picture we can make out the Equator and Prime Meridian. What are those?
The Equator is the middle latitude line and is O degrees. Countries near by the Equator are some of the hottest places on the earth. The Equator goes from the East to the West
The Prime Meridian, is the exact opposite of the Equator. The Prime Meridian is the middle longitude line, but is also O degrees. The Prime Meridian goes from the North to South.
Hemisphere is such a long word, what does it mean? Hemi= Half/Sphere= 3D circle (earth). If you do the math one hemisphere is half the earth. The Equator and the Prime Meridian split the world into four hemispheres. North hemisphere, South hemisphere, East hemisphere, and the West hemisphere.
What garden can I find the Compass Rose in? None silly, a Compass Rose is not a flower, a Compass Rose tells us which direction is which. A Compass Rose is on a map. A Compass Rose shows the Cardinal Direction- North, South, East, West. A Compass Rose also shows the Intermediate Directions- North, South, East, West. Now when I ask you what a Compass Rose is I would like to hear a proper answer! :)
To me Scales are a really cool feature that comes with maps. An example of a scale would be:
Every four inches on the map = one Kilometer. At first it is confusing using scales, but once you get used to it, you can't stop measuring your whole map.

Eli's Mapping
Every geographer knows that a map is made of many important parts. Each part tells about something different. It goes beyond giving just direction like north, south, east and west. There are the imaginary lines called longitude that go around the earth north south. There are also imaginary lines that go east west and they are called latitude. The equator is zero degrees latitude and the prime meridian is zero degrees longitude. Longitude and latitude cut up the world into what looks like little squares. Hemispheres also divide up a map with the northern hemishphere, southern hemisphere, eastern hemisphere and western hemisphere. Time zones split the world into different times according to when it is daylight and night time. It can be night in one part and day in another part at the same time. Maps are not as big as the real world so they need a scale. A scale helps you to understand the distances. For example one centimetre on a scale can equal one kilometer on the ground. Finally there is the legend. There are different kinds which give information about what the map is about. For example shading can show the number of hurricanes if it is a map about weather. So whether you are lost in Burnaby or in the jungles of Peru it is really important to read a map because you never know when google earth and your internet might not be working.
mapping paragraph
On every map there is a grid. This grid is made up from latitude lines, which run from east to west and longitude lines which run north to south. These lines are used to measure degrees. In the middle of the globe is the equator. The equator is 0 degrees latitude. The prime meridian is 0 degrees longitude. The world is split into four halves, called hemispheres. Northern hemisphere, Southern hemisphere, Eastern hemisphere and Western hemisphere.
On each map has one compass rose. This compass usually tells you where the north part of the map is, but sometimes it might also say, East, South and West. On a map it also has a scale. A scale shows the distances from one place to another. The earth is divided into 24 different time zones of 24 hours a day. If one place would be night then in another place it would be day.

Map Elements
The elements on a map are Latitude, Longitude, the Hemispheres, Directions, Time Zone, Scale and the Map Legend. Latitude lines are imaginary lines on a map that goes east to west and Vic versa. Longitude lines are imaginary line on a map that goes north to south and Vic versa. Earth is divided up by these two types of lines. Latitude and Longitude are measured in Degrees. The middle latitude line is called the Equator the middle longitude line is called the Prime Meridian. The Equator is 0 degree latitude and the Prime Meridian is 0 degree longitude.
Hemisphere means, half a sphere (hemi=half sphere=3D ball). By using the Equator and the Prime Meridian you can split the world into 4 Hemispheres. The Hemispheres are North, East, West and South. These directions are known as the Cardinal Directions. There are also Intermediate Directions which are, Northeast, Northwest, Southeast and Southwest. The way you know where each direction is, is by using a Compass Rose. A Compass Rose on a map points to each direction. By using a Compass Rose and a Scale you can find out if you go 2 inches South how long that is in Miles, Kilometers and sometimes Feet or Yards. The only way to do this is by using your Scale on a map and a ruler. The Scale shows you how many Kilometers you go in measurements as little as an inch.
