Sue Venir is planning a visit to a castle in Shropshire.
Watch along with this clip to find out how she uses a map to find the way.

What is a map?
A map is a two-dimensional drawing of an area .
Maps can show the countryside, a town, a country or even the whole world.
They are used to help plan routes from one place to another, or to find
certain features such as castles or hills.
Dahl class geography lessons
Different types of map are used for different things depending on whether you
are walking, driving or even flying somewhere.
Maps can be on paper or on a mobile phone, tablet or computer.
How to use a map
The top of most maps is north and a compass can be used to find
which direction north is. Compasses show four directions - north, east,
south and west .
The needle always points north, so when that is lined up with the map it is easy
to see in which direction things are.
Maps are not drawn to the same size as the ground because they would be far
too big! Instead they are drawn to a smaller scale .
The scale on a map is a set of numbers that can be used to compare distances
and can be written, for example, as 1:25,000.
This means that the actual size of the ground is 25,000 times bigger than it is
on the map.
The same scale can also be written as 4cm to 1km, so every four centimetres on
the map is one kilometre in real life.

Have a go at drawing a map of your street or local area. Download and print out the activity sheet below.
If you can’t download this it looks like this. You can just draw it in your book or on a plain piece of paper and

Contours, keys and symbols

STEP 1)
Sue Venir is celebrating her friend's birthday with a camping trip.
Her friend has given her a map so she can find her way to the campsite.
Watch this short film to find out how she uses contours, keys and symbols to
read the map.
You can watch the film as many times as you want until you think you
understand it.
Now read this summary of what you should have learned
Map reading
To be able to understand maps, it is important to have map-reading skills.
Maps are usually too small to contain lots of writing so instead there
are symbols which show important landmarks, places and areas.
There is usually a key at the side of the map which explains what these
symbols mean.
Symbols and contours
Symbols are generally the same on most types of map.
For example, buildings or tourist attractions are shown with blue symbols.
Dahl class geography lessons
Different types of roads are shown in different colours - blue for
a motorway, red for a main road and yellow or orange for narrower
roads .
Dotted green lines are usually used to show footpaths.
Some maps, especially ones that people use to find their way around the
countryside, contain brown contour lines.
These are lines that show high and low areas of land.
The contour lines join up areas of the same height, and when they are
close together it means the hill or mountain is steep.
When they are far apart it means the land is gently sloping,
or undulating .
This is useful to know when planning a route, to see whether it is going to
be a hike up a steep mountainside or a walk on flat ground.

Time Zones

Now read this information
Time in different parts of the world
As the Earth rotates on its axis , the Sun only shines on the side of the Earth that it is facing. This means:
• it is daytime for the parts of the Earth that have the Sun shining on them
• it is night-time for places that are on the opposite side of the Earth and are in the shade
As it is night in some parts of the world while it is day in other parts, different places in the world have different
times. This is why the world is divided into 24 different time zones. One for each hour in a day.
Very large countries that are spread out across many time zones, such as Russia or the USA, are divided into separate
time zones. Most smaller countries keep to the same time zone even if part of them falls outside a meridian line.
When it's daytime in the UK, it's night-time in Australia.
Glossary
Axis - a real or imaginary straight line going through the centre of an object that is spinning, or a line that divides a
symmetrical shape into two equal halves:
Dahl class geography lessons
The earth revolves around the axis that joins the North and South Pole
Time zones- one of many equal parts into which the world is divided. In any place within each part, the particular
point in the day is the same, and is an hour in front of or behind that in the parts on either side:
If you go from New York to London, you cross five time zones.

Lesson 4
Latitude and longitude
Go to BBC website https://www.bbc.co.uk/bitesize/articles/zr7j7nb
Learn
What are latitude and longitude?
To help locate where a place is in the world, people use imaginary lines:
• To find out how far north or south a place is, lines of latitude are used. These
lines run parallel to the Equator.
• To find out how far east or west a place is, lines of longitude are used. These lines
run from the top of the Earth to the bottom.

have an address to send things to!

Read this information about hemispheres
Hemispheres
The Equator is at the centre of the lines of latitude and is at 0° latitude.
Anything lying south of the Equator is in the Southern Hemisphere and is
labelled °S. Anything lying north of the Equator is in the Northern
Hemisphere and is labelled °N. The North Pole is 90° N and the South Pole is
90° S.
The line labelled 0° longitude is called the Prime Meridian or the Greenwich
Meridian and runs through London. Anything lying east of the Greenwich
Meridian is in the Eastern Hemisphere and is labelled °E. Anything lying west
of the Greenwich Meridian is in the Western Hemisphere and is labelled °W.
In 1932, Amelia Earhart set out to be the first woman to fly on her own across
the Atlantic ocean from Canada to Northern Ireland - over 3000 km! Watch

LESSON 5
Mountains
READ AND LEARN
What are mountains?
Mountains are areas of land that are much higher than the land surrounding
them. They are higher and usually steeper than a hill and are generally over 600
metres high. They are often found together in a group called a mountain range.
Some well-known mountain ranges in the four countries that make up the UK
include:
• the Cairngorms in Scotland
• the Pennines in England
• the Mourne Mountains in Northern Ireland
• Snowdonia in Wales
Sue Venir is climbing to the top of Mount Elbert, the tallest of all the Rocky
Mountains. The Rocky Mountains is a mountain range that stretches all the way
from the USA into Canada. Using this ‘BBC Bitesize’ website. Watch this short
animation to find out more about mountains.

Dahl class geography lessons
READ AND LEARN
How are mountains formed?
The highest mountain ranges are created by tectonic plates pushing
together and forcing the ground up where they meet. This is how the
mountains of the Himalayas in Asia were formed.
Tectonic plates are also at work under the Atlantic Ocean, but
instead of forcing the ground up, the two plates in the middle of the
Atlantic Ocean are actually moving apart in opposite directions. This
causes lava to erupt out of the gap that is left. As it cools down, the
lava creates a long line of mountains - the longest mountain range on
Earth.
Other mountains - usually those that stand on their own - are created
by ancient volcanoes. Ben Nevis in Scotland was once a very
large active volcano. It last erupted millions of years ago and the
eruption was so violent that it caved in on itself.
The highest mountains in the UK are:
• Ben Nevis in Scotland (also the highest in the UK)
• Scafell Pike in England
• Slieve Donard in Northern Ireland
• Snowdon in Wales
