II. MOST ESSENTIAL LEARNING Using models, relate:
COMPETENCIES (MELCs) 1. the height of the Sun in the sky to the amount of energy received
2. the latitude of an area to the amount of energy the area receives
3. tilt of the Earth and the seasons.

III. CONTENT/CORE CONTENT The relationship of the Seasons and the position of the Sun in the sky
IV. LEARNING PHASES AND LEARNING ACTIVITIES
I. Introduction (Time Frame: Day 1)
In your previous lesson, you have learned about the relations between Earth’s tilt to length of daytime, the length of daytime to
the amount of energy received and the position of the Earth in its orbit to the height of the Sun in the sky. For the continuation of
the lesson you will learn more about how the amount of energy received by the Earth’s surface and the seasons on Earth.

Season is a division of the year marked by changes in weather and the amount of daylight. On Earth, seasons are the results of
Earth’s orbit around the Sun and Earth’s axial tilt relative to the ecliptic plane.

Study the pictures and try to answer the

questions that follow.

Figure 1. Shows the tilt of the Earth to the length of daytime.

You have learned that the Sun appears to move from east to west because of the rotation of the Earth. The position of the
Earth’s axis relative to the sun changes as it moves around the sun. This results in a change in the observed height of the Sun
above the horizon. It is observed that the Sun trace a higher path above the horizon during summer, and a lower path during
winter. Thus, the Sun takes a greater amount of time to travel from East to West during summer and takes shorter time during
winter. This means that more energy is hitting the Earth during summer than winter.

Direct and Indirect Rays of the Sun

Depending on the time of year, the angle at which the Sun’s rays strike the Earth will vary. The Sun’s rays strike Earth’s surface
most directly at the equator which focuses the rays on a small area. The Sun’s rays strike the surface at a slant near the poles
causing the rays of the sun to scatter over a wider area. The more focused the rays are, the more energy an area receives, and
the warmer it is. As a result there are parts of the Earth that receive direct and some receive indirect sunlight as shown in the
figure below.

During summer when the sun is high in the sky , it directly cast its rays on the surface. We call these direct sun rays. Heat is more
more concentrated and cover a smaller area which then tends to be warmer.
During winter when the sun is lower in the sky, its rays strike the Earth at an angle. We call these indirect sun rays. They are more
diffused and covers a broader surface area. The figure below illustrates direct and indirect sun rays.

The Seasons
We have seasons because Earth's axis is tilted. As the Earth orbits the Sun, its tilted axis always points in the same direction as
shown in Figure 1. There are times that the North Pole points to the sun and there are times that it is pointing away from the sun.
Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, days
grow long, and weather warms. It is summer in the Northern Hemisphere. For part of the year that the Northern Hemisphere leans
away from the sun’s light. Days grow short, and temperatures drop. This is winter.
Many areas in the world are experiencing four different seasons. These seasons are as follow:
• Summer –is the hottest of the four temperate seasons
IV. LEARNING PHASES AND LEARNING ACTIVITIES
• Winter – is the coldest season of the year.
• Spring – It is the season that happen after winter. This is the time when trees bloom.
• Autumn – It is the season that happens after summer that is often called fall because leaves fall from the trees at that
time.
Looking at Figure 1 , we can see the following:
December: It is Summer at the south of the equator and winter
at the north of the equator. The Sun shines directly on the
Southern hemisphere and indirectly on the Northern
Hemisphere.
March: It is fall at the south of the equator and spring at north
of the equator. The Sun shines equally on the Southern and
Northern Hemisphere.
June: It is winter, south of the equator and summer at north of
the equator. The Sun shines directly on the Northern Hemisphere Figure 2. location of the Earth at different times as it
and indirectly on the Southern Hemisphere. revolves around the sun.

September: It is spring at south of the equator an d fall north of change-but-why/
the equator. The Sun shines equally on the Southern and Northern
Hemisphere.
In the Philippines, temperature and rainfall are the bases for the seasons. There are two major seasons in our country: the rainy
season, from June to November; and the dry season, from December to May. The dry season may be subdivided further into
cool dry season, which happens from December to February and the hot dry season, from March to May. The Philippines lies in
the tropical region. This region receives strong amount of sunlight all year. This is the reason why there are only two seasons in the
Philippines.
