CONTENT OF THE LESSON
LESSON 1 – INTRODUCTION
Earth, our home, is the third planet from the sun.
Earth is the only planet known to have an atmosphere containing free oxygen, oceans of liquid water on its surface, and, of course, life.
The earth is the third planet and the only that living things are found.
The sun, moon and the star are the major natural source of light to the earth.
THE SUN
The sun is the biggest object in the solar system that is give light to the earth.
It is the main source of natural light and heat on earth.
The sun is at centre of the solar system.
The movement of the sun is false (not true) and this movement is called Apparent Movement of the Sun because the sun does not move.
Apparent movement of the sun is caused by the rotation of the Earth about its axis.
THE MOON
The moon is the only natural satellite on earth.
There are many moon in the solar system and the earth has one of them that shines bright in the night sky.
THE STARS
The stars also produce light just the sun and the moon that shine on earth in the night sky.
The light is called self luminous.
LESSON 2 – ROTATION AND REVOLUTION OF THE EARTH
Rotation and revolution are the two types of earth’s movements with the sun at the center of the solar system as the major source of all life and energy here on earth.
ROTATION OF THE EARTH
Rotation can be defined as 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.
5. It caused apparent movement of the sun.
REVOLUTION OF THE EARTH
Revolution of the earth can be defined as 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 3 – ECLIPSE OF THE SUN AND THE MOON
The eclipse is the 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.
There are types of eclipse,
1. Solar eclipse
2. Lunar eclipse
1. SOLAR ECLIPSE
Solar eclipse is known as eclipse of the sun.
The eclipse of the sun is when the moon comes in between the sun and the earth.
2. LUNAR ECLIPSE
Lunar eclipse is also known the eclipse of the moon.
The eclipse of the moon is when the earth comes in between the the sun and the moon.
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; then, the teacher –
2. Teacher organizes pupils in groups or pairs depending on the size of the class.
3. Teacher displays chart showing the earth, sun, moon and the stars and asks them to discuss the relationship with the natural bodies.
Pupil’s Activities – Discuss the importance of the sun, moon and stars on earth.
4. Teacher listens to the groups or pairs and introduce the lesson.
Pupil’s Activities – Pay attention to the lesson introduction to understand the concept of the lesson.
5. Teacher uses the group’s or pair’s responses to lead a discussion on the relationship with the earth, sun, moon and the stars.
Pupil’s Activities – Participate actively in the class discussion.
6. Teacher asks pupils if the sun moves or not.
Pupil’s Activities – If yes, explain.
7. Teacher tells pupils, the sun doesn’t move. The sun only appears to move across the daytime sky because of the rotation of the earth.
8. Teacher uses the pupil’s responses in activity 6 and the statement in activity 7 to introduce and explain the meaning on the earth’s movement.
Pupil’s Activities – Listen to the teacher’s explanation.
7. Teacher uses model charts to explain the meaning and relationships between rotation and revolution of the earth.
Pupil’s Activities – Identify the movement of earth’s rotation and revolution.
8. Teacher uses the time, variation day and night, seasons and wind to discuss the effects of rotation and revolution of the earth.
Pupil’s Activities – Analyze the effects of earth’s movement on the earth with appropriate illustrations.
9. Teacher guides pupils as a group or pair to demonstrate and discuss the eclipse of the sun and the moon using balls of different sizes and flash light.
Pupil’s Activities – Demonstrate the eclipse of the sun and the moon using balls of different sizes and flash light.
10. Teacher summarizes the lessons on the board with appropriate lesson evaluation.
Pupil’s Activities – Participate actively in the summary of the lesson by responding correctly to the lesson evaluation and write as instructed.
CONCLUSION
To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
