Opening Prayer
Dear Lord, we are gathered in your presence this day to glorify and honor your
name. Please forgive us our trespasses and wrong doings. Help us to be
more understanding and concerned to others because this is your will.
Thank you Lord for all the blessings that we received.
Please give us an open mind and heart so we can understand thoroughly all
the things that we have discussed in the class.
All these, we pray in your name. Amen

Week 01: Lesson 1

Essential Question
What influences weather and climate patterns around
the globe?

Locating Places Using
Coordinate Systems
Week 01: Lesson 01

Lesson Objectives
• describe the location Philippines with respect to the continents
and oceans of the world
• explain how the places on Earth are located using a coordinate
system

Essential Question
How can we find the position of a place on Earth?

MONLIMAR DEVELOPMENT ACADEMY, INC.
We can find positions of different places using the following objects:
Junior High School I Grade 07 - Science
Maps Globe GPS Compass

Let’s Focus!
Globe
Maps
• Is a two-dimensional graphical representation of an
area, land or sea depicting physical features
• A three dimensional spherical model of the Earth

Essential Question
Observe the map what do they have in common?
They both have lines horizontal and vertical lines that intersect with each other.

Imaginary Lines
• The imaginary lines circling the globe in an
east-west direction are called the lines of
latitude (or parallels, as they are parallel to the
equator).
• They are used to measure distances north and
south of the equator. The lines circling the
globe in a north-south direction are called lines
of longitude (or meridians).
• Since the location of the Earth is a sphere, the
measurement used is called degree

Latitudes
• Horizontal lines that run from east to west of a
map or globe.
Longitudes
map or globe.

Latitudes
map or globe.
• The starting line of latitude measurement is
called equator.

Equator
• Divides two hemispheres of the Earth
• The Northern and Southern Hemisphere

Latitude of a Place Affects the Climate Pattern

Longitude
• Longitude lines are a numerical way to
show/measure how far a location is east or west
of a universal vertical line called the Prime
Meridian.
• The starting line of Longitude measurement is
called Prime Meridian.

Longitudes
• Divides two hemispheres of the Earth
• The Western and Eastern Hemisphere

Key Concepts
• The Latitude and Longitude degrees represent exact places on Earth.
• When these latitudes and longitudes are combined (intersect) we can locate
any place on a map or a globe.

Locating Places Using Geographic Coordinate System
Week 01: Lesson 01

Geographic
Coordinate System
• System that is used to locate places using
degrees of latitude and longitude.

Coordinates
• Are pair of numbers that describe the
position of a point
• The coordinates of a place represents by
its degrees of latitude and longitude.

Coordinates
30 ° S, 60 ° W

Coordinates
30 ° S, 60 ° W
STEPS IN LOCATING
COORDINATES
First step is to find the
location of the latitude.
Locate what hemisphere it
was located.
Determine the degree of
the latitude and longitude.
Once the degree is located
draw lines for each
degrees.
Locate where the two lines
meet or intersect.

Locating Places Using Coordinate Systems
End of Lesson 1

Location of the Philippines:
Land Masses and Bodies of Water
Week 02: Lesson 02

Location of the Philippines
• The Philippine archipelago consists of a chain of about 7,641
islands, as well as bodies of water that lie around and between the
island. In this lesson, you will demonstrate an understanding about
the location of the Philippines with respect to the continents and
oceans of the world.
• A geographic coordinate system is a system that uses a three-
dimensional spherical surface to determine locations on the Earth.
Any location on Earth can be referenced by a point with longitude
and latitude coordinates.
