CONTENT OF THE LESSON  

WEEK 7

LESSON 1

INTRODUCTION

Earth, our home, is the third planet from the sun. It 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 SOLAR SYSTEM

The solar system comprises of the sun and the nine (9) planets that move around it. Namely –

1. Mercury

2. Venus

 

 

3.. Earth

4. Mars

5. Jupiter

6. Saturn

7. Uranus

8. Neptune

9. Pluto

 

NATURAL BODIES IN THE SKY

The sky is the space above the earth, the components of the sky are:

1. The cloud

2. The sun

3. The moon

4. The star

 

LESSON 2 – ROTATION AND REVOLUTION OF THE EARTH

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

The Sun is the center of the Solar System and 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.

 

WEEK 8

LESSON 3

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 4 – DESCRIPTION OF ECLIPSE, CLIMATE AND SEASONS

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.

 

CLIMATE

  • Climate is the average weather conditions over a given period of time. It is the change in weather over a period of time or given place.

 

SEASONS

Seasons are the period of the year marked by special climate conditions. There are four (4) major seasons, namely – the spring, summer, fall and winter.

 

 

A season is a period of the year that is distinguished by special climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly.

A season is a division of the year marked by changes in weather, ecology, and amount of daylight.

 

LESSON 5 – REVISION AND WEEKLY ASSESSMENT (TEST) 

 

ASSIGNMENT

Find out –

1. The meaning of satellite.

2. Three (3) examples of satellites.

 

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 students some questions; then, the teacher –

2. Illustrates the components of the solar system using the chart.

3. uses models/charts to explain the rotation and revolution of the earth and the moon.

Student’s Activities – Observe the illustrations.

4. Demonstrates eclipse of the sun using balls of different sizes and flash light.

Student’s Activities – Repeat the teacher’s demonstrations of the eclipses.

5. Leads discussion on seasons of the year.

Student’s Activities –

  • Participate in the discussions on seasons of the year.
  • Draw and label the solar system.

6. Summarizes the lesson on the board.

Student’s Activities – Copy as the teacher writes.

 

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

 

LESSON EVALUATION 

Ask students to:

1. List components of the solar system.

2. Discuss the following:

 

 

a. night and day

b. seasons of the year.

3. Explain the causes of the eclipse of the sun and the moon.
