14. LET’S ANALYZE
How did you find the activity?
What was your basis in identifying the correct
answer in each picture?
What concepts did you find out?
15. LET’S DISCUSS!
Earth-Sun Relationships
• Daily life on Earth is influenced by the dynamic relationship
between the Earth and the Sun.
• The amount of direct sunlight reaching the Earth's surface plays
and important role in affecting the temperature of different
places.
• The Earth's rotation determines when we receive sunlight, giving
us day or night.
• The Earth's tilt and its revolution around the sun result in the
four season.
16. CAUSES OF SEASONS
There are two major causes for seasons on Earth.
1. the tilt of the earth on it's axis
2. position of the earth in relation to the sun
(revolution)
18. WHAT IS A SEASON?
• A traditional division of the year based on unique weather
conditions.
• In temperate regions, there are four seasons, spring summer,
autumn and winter, while in tropical countries there are often only
two, a dry season and a rainy season.
• The seasons in the Northern Hemisphere and Southern
Hemisphere are in opposite.
• During seasons, hours of daylight and weather may vary greatly
depending on your location on Earth.
19. WHAT ARE THE FOUR SEASONS IN TEMPERATE
REGIONS? (NORTHERN HEMISPHERE)
SPRING
• This season lasts from
March 21 to June 21.
• This season usually has the
most severe weather.
• New plants begin to
appear during this season.
• The cycle of life starts.
20. WHAT ARE THE FOUR SEASONS IN TEMPERATE
REGIONS? (NORTHERN HEMISPHERE)
SUMMER
• During summer in the Northern Hemisphere,
the earth is tilted towards the Sun.
• This results in the Northern Hemisphere
getting direct rays from the Sun.
• The summer lasts through June, July, August.
• Fruits, vegetables, and other plants are in full
growth.
• The sun is at it's hottest and brightest during
this time.
• The amount of daylight exceeds the amount
of night hours.
22. WHAT ARE THE FOUR SEASONS IN TEMPERATE
REGIONS? (NORTHERN HEMISPHERE)
AUTUMN
• Also known an FALL
• This season starts in September
and lasts through the end of
November.
• Decidas trees shed their leaves
Leaves will changes a red brown
color before falling.
23. WHAT ARE THE FOUR SEASONS IN TEMPERATE
REGIONS? (NORTHERN HEMISPHERE)
WINTER
• During winter, the earth is tilted away from
the Sun.
• This results in the Northern Hemisphere not
getting strong direct rays from the Sun.
• This season starts in December and goes
through February.
• The weather is cold, and there is usually snow
and ice.
• The days are short and the temperature is low.
• A cool fact is we are actually closer to the Sun
in the winter than in the summer.
24. WHAT ARE TWO SEASONS IN TROPICAL COUNTRIES
(PHILIPPINES)?
Dry Season Wet Season
25. DRY SEASON
• Summer months
• During March, April, and ends
May
• Rainfall: dry
• Temperature: cool
• Amihan/Northeast monsoon
facilitates the dry season
26. WET SEASON
• Rainy months
• During June, July, August,
September and October
• Rainfall wet
• Temperature: hot
• Habagat/Southwest monsoon
facilitates the Philippines wet
season
27. LET’S APPLY
Watch this vlog “Rainy Season Tips" by The Agrillenial.
And, learn how this type of season affects farming.
As a learner, what further ideas can
you share and suggest to our
farmers that will help them in their
work?

29. ASSIGNMENT
Direction: Create a concept map about
the four seasons on earth and provide a
brief statement explaining your work.
Your concept map will be rate according
to the rubrics provided.
Editor's Notes
Earth has seasons because its axis is tilted. Earth’s axis is always pointed in the same direction, so different parts of Earth get the sun’s direct rays throughout the year. For example, in summer, the sun's rays hit that region more directly than at any other time of the year.
The Earth's axis is not oriented vertically, but is tilted by 23.5 degrees. The north end of the axis is always pointed toward the North Star as the Earth revolves around the sun. This tilt, combined with its revolution around the Sun, causes seasonal changes. (When it’s summer in the northern hemisphere, it’s winter in the southern, and vice versa.) If the axis was not tilted, our year-round climate would be rather boring and many places on Earth wouldn’t receive much light!
Because moisture and warmth are crucial to thunderstorms, it makes sense that they would occur more often in the summer, particularly in humid areas such as the southeastern United States. The rising moisture that has lost an electron carries a positive charge to the top of the cloud.
