BASIC SCIENCE 

BASIC SCIENCE AND TECHNOLOGY

FIRST TERM

WEEK 6

PRIMARY 6

THEME – EARTH’S MOVEMENT 

PREVIOUS LESSON –

TOPIC – THE EARTH AND ITS MOVEMENT 

LEARNING AREA 

1. Earth and Its Movement – Rotation and Revolution of the Earth

2. Eclipse (Solar and Lunar)

3. Revision and Test

 

PERFORMANCE OBJECTIVES

By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and be able to:

1. describe the two important movements of the earth (rotation and revolution) and their effects.

2. explain the causes of lunar and solar eclipse and their effects e.g. tide

3. discuss some effects of the earth movement on the environment

4. identify the major sources of light for the earth and other planets.

 

ENTRY BEHAVIOR

The pupils are required to already have learned to the solar system.

 

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

Charts

Pictures of moon phases

Light from a Torch light

Model of the Earth, Moon and the Sun

 

 

METHOD OF TEACHING – Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

LESSON ONE – INTRODUCTION 

The earth is the third planet and the only that living things are found.

Rotation and revolution are the two types of earth’s movements.

 

THE SUN 

The Sun is the center of the Solar System and the major source of all life and energy here on Earth.

Since the beginning of history, human beings have understood the Sun’s importance to our world, it’s seasons, the diurnal cycle, and the life-cycle of plants.

 

 

EFFECTS OF THE INTERACTION BETWEEN THE SUN AND THE EARTH 

1. Rotation

2. Revolution

3. Eclipses (Solar and Lunar)

 

LESSON TWO – ROTATION OF THE EARTH 

This is the movement of Earth around its own axis in every 24 hours.

It takes the earth 24 hours to complete a rotation around its axis.

 

EFFECTS OF EARTH’S ROTATION 

1. It causes day and night.

2. It causes time difference.

3. It causes the direction of winds.

4. It causes ocean currents to be deflected.

 

REVOLUTION OF THE EARTH 

This is the movement around the sun in every 365 days (or a leap year – 366 days) making one years.

It takes the earth 365 day (a year) to complete its movement around the sun.

 

EFFECTS OF THE EARTH’S REVOLUTION 

1. It causes different season. For example, the rainy (summer) and dry (winter) season.

2. It causes variation in the length of day and night.

3. It causes eclipse of the sun.

 

 

LESSON THREE – ECLIPSE OF THE SUN AND THE MOON 

This is complete or partial darkness on the face of the earth. At this time, the earth is unable to receive light from the sun as a result of the moon (solar eclipse) coming in between the sun and earth or the earth (lunar eclipse) comes between the sun and the moon.

 

  • Eclipse of the Sun – Solar Eclipse 

This is when the moon comes in between the sun and the earth.

 

  • Eclipse of the Moon – Lunar Eclipse 

This is when the earth comes in between the the sun and the moon.

 

SOURCES OF LIGHT FOR THE EARTH

1. The Sun

2. Moon, and

3. The Stars

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Uses simple activities to illustrate – the Earth’s rotation on, its Axis and its effects, the earth’s revolution around the Sun and its effects. The Earth’s Orbit, lunar and solar eclipses;

Pupil’s Activities – Demonstrate causes of day and night.

Pupil’s Activities Observe stars in the night, notice the constellation.

Pupil’s Activities – Read about stars constellation and learn the names of some of the stars.

 

 

3. Initiates and guides discussions about causes of some of the observable natural phenomena like tides, seasons, moon phases, etc. and their effects on the environment, e.g. heavy rains and tide destroying the environment through erosion;

Pupil’s Activities – Participation in class discussion.

4. Guides pupils to observe and record changes in the moon (moon phases);

Pupil’s Activities – Keep record of moon phases.

 

CONCLUSION

  • To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson – living and non living things.
  • Next Lesson –
