X. The number line. The coordinate system in a plane. The student:

2) finds the coordinates of the grid given in the drawing in the coordinate system in the plane;

3) draws the grids with given integer coordinates (of any sign) in the coordinate system in the plane.

Introductionmeb30da592aa81d06_1528450127855_0Introduction

Teacher prepares for the each pair of the students:

- the atlases containing the map of Poland,
- the globes.

Revision of the coordinate system.

The students answer the following question:

How can we identify the position of the point in the coordinate system?

Proceduremeb30da592aa81d06_1528446435040_0Procedure

The teacher introduces the topic of the lesson: discovering the notion of the geographical coordinatesgeographical coordinatesgeographical coordinates. The students are going to specify the position of the points on the mapmapmap and on the globe.

Students answer the following questions:

What is the map used for?

What is the globe used for?

The teacher explains that specifying the position of points on the mapmapmap and on the globe is similar to specifying the points in the coordinate system.

The students work in pairs. Teacher gives the atlas to each pair of the students. The students are going to analyse the cartographic grid which covers the map of Poland.  

The students analyse the position of the lines of the grid and the method of its description. They can use the Internet to search for the terms they don’t know ( e.g. the meridians, the parallel arcs). As the result of their considerations they come up with the following conclusions:

[Interactive illustration]

Teacher explains that the position of the point on the map is determined by the geographical coordinatesgeographical coordinatesgeographical coordinates: the value of the parallel arcparallel arcparallel arc (the latitude) and the value of the meridianmeridianmeridian (the longitude). The geographical coordinates are measured in degrees. One degree is divided into 60 minutes.

Using the mapmapmap the students answer the following questions:

What parallel arcs run via Poland?

What hemispherehemispherehemisphere Northern or Southern is Poland situated in?

What meridians run via Poland?

Which hemisphere Eastern or Western is Poland situated in?

The students draw following conclusions, for example:

- The parallel arcs 50°, 51°, 52°, 53° and 54° subsequently pass via Poland . Our country is situated  in the Northern Hemisphere.
- The meridians 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24° subsequently pass via Poland. It is situated in the Eeastern Hemisphere.
meb30da592aa81d06_1527752263647_0- The parallel arcs 50°, 51°, 52°, 53° and 54° subsequently pass via Poland . Our country is situated  in the Northern Hemisphere.
- The meridians 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24° subsequently pass via Poland. It is situated in the Eeastern Hemisphere.

Teacher specifies students conclusions:

- The point on the mapmapmap which corresponds with the specified place in Poland has got the latitude North (N), because Poland lies on the Northern HemispherehemisphereHemisphere.
- The point on the map which corresponds with the specified place in Poland has got the longitude East (E) because Poland lies on the Eastern Hemisphere.

The students work in pairs using the atlases. They are going to give the geographical coordinatesgeographical coordinatesgeographical coordinates of the specified Polish cities.

Example 1

Read the geographical coordinatesgeographical coordinatesgeographical coordinates of Tarnow, the city situated near Cracow.

Tarnow lies at the intersection of the meridianmeridianmeridian of  21° and the parallel arcparallel arcparallel arc of 50°, so we write the geographical coordinates of Tarnow as:

21 degrees of east longitude (21°E) and 50 degrees of north latitude (50°N).

Task 1

Read the geographical coordinates of specified cities. Round up the result to the nearest degree:

a) Lublin,

b) Warszawa,

c) Gdynia.

Task 2

The geographical coordinates of the cities visited by the students during their school trip are presented below.

19°27'E 51°47'N

18°37'E 53°02'N

18°00'E 53°07'N

19°02'E 54°02'N

18°38'E 54°22'N

Describe the route of the trip giving the names of the cities.

The student should give the following names of the cities: Łódź, Toruń, Bydgoszcz, Malbork, Gdańsk.

The students work in pairs using the globe.

Task 3

a) Find the parallel arc of 0° (the equator ) and the meridian of 0° (the meridian of Greenwich).
b) Give an example of the country which lies entirely on the Northern and Eastern Hemisphere at the same time.
c) Give an example of the country which lies entirely on the Southern and Western Hemisphere at the same time.
d) Give the approximate values of the geographical coordinates of Madrid, New York, Sydney.
meb30da592aa81d06_1527752256679_0a) Find the parallel arc of 0° (the equator ) and the meridian of 0° (the meridian of Greenwich).
b) Give an example of the country which lies entirely on the Northern and Eastern Hemisphere at the same time.
c) Give an example of the country which lies entirely on the Southern and Western Hemisphere at the same time.
d) Give the approximate values of the geographical coordinates of Madrid, New York, Sydney.

The teacher points out that the border between the Northern and Southern HemispherehemisphereHemisphere is determined by the equator and the border between the Eastern and Western Hemisphere is determined by the meridianmeridianmeridian of 0°.

An extra task:

Choose the European country and plan a trip. Write down the names and the geographical coordinatesgeographical coordinatesgeographical coordinates of the visited countries. Use the atlas with the mapmapmap of the country you have chosen.

Lesson summarymeb30da592aa81d06_1528450119332_0Lesson summary

Students do the summarising exercise.

Then together they sum up the classes drawing the conclusions to memorise:

- The parallel arc of 0°, called the equator , determines the border between the Northern and Southern HemispherehemisphereHemisphere.

- The parallel arc of 0°, called the equator , determines the border between the Northern and Southern Hemisphere.

- It is said that places which are situated on the Northern Hemisphere have the north latitudenorth latitudenorth latitude (N), and the ones situated on the Southern Hemisphere have the south latitudesouth latitudesouth latitude (S).
