Name of the Topic : The Interior of the Earth

LEARNING OUTCOMES 1. The pupil will be able to recognize the changes in the interior

Of the Earth and its impact of the surface of the earth.

2. The pupil will be able to understand the inner parts of the earth.

3. The pupil will be able to create awareness about the various actions

happens in the inner of the

Content Analysis

FACTS 1. Ups and downs appeared on the earth due to some movements

From inside the earth and various processes

2. When goes deeper in to the earth, temperature and pressure

Increases.

3. The depth of the deepest mines on the earth is only about 9Kms.

4. The lava that comes to the surface of the earth through Volcanoes

are from a depth, maximum of just 64 Kms.

5. The radius of the earth, that is the distant from the centre of the earth

To surface is about 6371 Kms.

6. Earth interior consists of Crust, Mantle, outer core and inner core.

CONCEPT Interior of earth comprises Crust, Mantle,outer core and inner core

And the temperature and pressure varies on each layer.

CLASSROOM INTERACTION PROCEDURE EVALUATION

INTRODUCTION

Teacher enters the class room and interacts with the pupil.

Then he asks the students the following questions.

1. Are you like songs? Then teacher plays a song in the classroom with the help of the

Laptop “ Ganga Yamuna sangama samathala bhoomi”. Did you like the song? What is the theme of this song? After consolidating the answers teacher enters into the topic.

Yes

Yes

ACTIVITY -1 Teacher shows the pictures of the earth trough OHP. Then teacher

explains that the surface of the earth consists of mountains, planes,

valleys, oceans, rivers etc.

Later he shows the pictures of mountain regions like Munnar, and

Wayanad and asks the following question.

Why these regions are generally characterized by Ups and Downs?

Later teacher explains that the Ups and Downs

occurred due to some movements from the inside the earth and

various processes.

Pupil watch the pictures

Pupil listen carefully

ACTIVITY 2 Teacher asks the following questions to the pupil

1. Have you ever seen well digging process in your locality?

2. Are you like to see the interior of earth?

Teacher shows a video which explains the interior of earth which

consists of Crust, Mantle, Inner core and Outer core.

Later teacher explains the peculiarities of each layer.

Yes Yes Pupil watch the video carefully and enthusiastically

ACTIVITY -3

Teacher shows a table which contains the Depth and Density of

different layers of interior of Earth through OHP

LAYER

Approximate depth

in KMs

Average Density

A Crust 0-40 2.9

B Mantle 40-2900 4.5

C Outer core 2900-5150 10.7

D Inner core 5150-6371 15

Then teacher divides the Pupil into 4 groups and gives activity

cards. Then teacher asks them to tabulate the depth and density

of different layers of the earth.

Later he asks the leaders of each groups to present their finding

and he consolidates their answers,

The crust has 0-40 km Depth and has 2.9 Density. The mantle has

40-2900 km depth and 4.5 Density. The Outer core has a depth of

2900-5150 km and density of 10.7. The Inner core has a depth of

5150-6371 Km and density of 15.

Pupil began to discuss They present their ideas Pupil listen carefully

FORMATIVE EVALUATION PROCEDURE

REVIEW

1. What is the reason for the ups and downs in the surface of the earth?

2. What change happens in temperature and pressure as we goes deeper and deeper

Into the earth?

3. Describe about the interior of the earth?

Follow up activity

When you go on a study tour make a note of the different land forms you

noticed?
