3. I. OBJECTIVES
• AT THE END OF THE LESSON, 75% OF THE LEARNERS ARE
EXPECTED TO:
1.DESCRIBE/RECOGNIZE THE UNIQUE CHARACTERISTICS OF
THE EARTH.
2.EXPLAIN THE IMPORTANT FEATURES OF THE EARTH
NECESSARY TO SUPPORT LIFE.
3.APPRECIATE THE FEATURES OF THE EARTH THAT SUPPORT
LIFE.
4. PICTURE ANALYSIS
Guide Questions:
1. Have a closer look to this planet Earth. How can you
describe it?
2. The planet Earth itself looks hopeful for supporting
life. Do you agree with me? Why or why not?
3. Do you agree with me that planet Earth is unique
from other planets?
5. ENUMERATE AT LEAST FIVE REASONS THAT MAKE THE PLANET
EARTH UNIQUE.

6. IDENTIFY THE FEATURES OF EACH PLANET BY ANSWERING THIS TABLE. PUT A
STAR IF THESE FEATURES ARE PRESENT AND IN HABITABLE AMOUNT. PUT AN X IF
ABSENT OR NOT IN HABITABLE AMOUNT.
Planets Life Water Plants Nutrients Ocean Land Sunlight
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
7. WHAT MAKES THE EARTH UNIQUE?
First: It is the only known planet with liquid
surface water in an amount conducive to life
evolving, remarkable for its precisely-tuned
amount of water, not too much to cover the
mountains, and not so little that it's a dry
desert. When viewing Earth from space,
there is one overwhelming feature and that
is the oceans of liquid water. In terms of
surface area, these oceans cover
approximately 70% of the Earth. What is
even more amazing than this percentage is
that a single drop of liquid water is yet to be
found on any other planet in the Solar
System. In this regard, the Earth is truly
unique.
8. • SECOND: IT IS THE ONLY KNOWN PLANET “JUST RIGHT” LOCATION IN THE SOLAR SYSTEM THAT
IS, THEY'RE FAR ENOUGH AWAY TO BE OUT OF THE HEAVY HEAT AND RADIATION ZONE, BUT NOT
SO FAR THAT THEY'RE EXTREMELY COLD. THIS JUST-RIGHT DISTANCE IS CALLED THE "HABITABLE
ZONE."
• THIRD: IT IS THE ONLY KNOWN PLANET "JUST-RIGHT" ASPECT OF EARTH IS ITS SIZE; IF IT WAS
MUCH SMALLER, IT WOULDN'T BE ABLE TO HOLD ON TO OUR PRECIOUS ATMOSPHERE, BUT MUCH
LARGER AND IT MIGHT BE A GAS GIANT TOO HOT FOR LIFE.
• FOURTH: IT IS THE ONLY KNOWN PLANET WHOSE MOON STABILIZES OUR PLANET'S ROTATION,
PREVENTING DRASTIC MOVEMENTS OF THE POLES THAT COULD CAUSE MASSIVE CHANGES IN
CLIMATE THAT SOME SCIENTISTS THINK COULD HAVE DOOMED ANY CHANCE FOR BUDDING LIFE
TO FORM OR EVOLVE. THE MOON ALSO HELPFULLY PULLS THE OCEAN'S TIDES, WHICH
SCIENTISTS SUGGEST MIGHT HAVE BEEN THE PERFECT PLACE FOR EARLY LIFE TO BEGIN
EVOLVING TO SURVIVE ON LAND.
• FIFTH: IT IS THE ONLY KNOWN PLANET WHOSE CORE GIVES US A SOURCE OF GEOTHERMAL
ENERGY, ALLOWS CYCLING OF RAW MATERIALS, AND SETS UP A MAGNETIC FIELD AROUND THE
PLANET THAT PROTECTS US FROM RADIATION.
9. SITUATION: IMAGINE YOURSELVES IN A UNIVERSE VOYAGE WHEREIN YOUR SPACESHIP
SUFFERS MECHANICAL PROBLEMS AND WILL BE FORCED TO LAND. FORTUNATELY, YOU ARE
PASSING THROUGH A YANIB SYSTEM, WHICH IS COMPOSED OF A SUN-LIKE STAR
SURROUNDED BY NINE PLANETS, SOME OF WHICH HAVE MOONS. BASED ON THE GIVEN
PROFILES, YOU HAVE TO DECIDE THE BEST PLACE TO LAND YOUR SPACESHIP.
•IN A WHOLE SHEET OF PAPER, WRITE DOWN YOUR CHOICE OF PLANET OR MOON AND
REASONS FOR CHOOSING SUCH. WRITE ALSO THOSE UNCHOSEN PLANETS/MOONS AND
REASONS. FOLLOW THE FORMAT BELOW TO BE GUIDED.
11. •GUIDE QUESTIONS:
1. ARE WE ALONE IN OUR SOLAR SYSTEM?
2. DOES LIFE EXIST IN OTHER PLANETS?
3. WHAT WOULD YOU CHANGE ABOUT THIS WORLD?
4. WHAT’S OUR BIGGEST MISTAKE AS HUMAN?
12. FILL-IN THE BLANK. FILL THE BLANKS WITH THE CORRECT WORD/S THAT WILL
MAKE THE STATEMENT CORRECT.
A. THE EARTH HAS _________IN ITS LIQUID FORM AT THE SURFACE, IN AN AMOUNT CONDUCIVE
TO LIFE EVOLVING, REMARKABLE FOR ITS PRECISELY-TUNED AMOUNT OF WATER, NOT TOO
MUCH TO COVER THE MOUNTAINS, AND NOT SO LITTLE THAT IT'S A DRY DESERT.
B. AN ____________THAT SHELTERS THE EARTH FROM THE WORST OF THE SUN’S RAYS.
C. “JUST RIGHT” __________IN THE SOLAR SYSTEM THAT IS, THEY'RE FAR ENOUGH AWAY TO BE
OUT OF THE HEAVY HEAT AND RADIATION ZONE, BUT NOT SO FAR THAT THEY'RE EXTREMELY
COLD. THIS JUST-RIGHT DISTANCE IS CALLED THE "HABITABLE ZONE."
D. "JUST-RIGHT" ASPECT OF EARTH IS IT’S ________; IF IT WAS MUCH SMALLER, IT WOULDN'T BE
ABLE TO HOLD ON TO OUR PRECIOUS ATMOSPHERE, BUT MUCH LARGER AND IT MIGHT BE A GAS
GIANT TOO HOT FOR LIFE.
13. E. EARTH'S__________ STABILIZES OUR PLANET'S ROTATION, PREVENTING DRASTIC
MOVEMENTS OF THE POLES THAT COULD CAUSE MASSIVE CHANGES IN CLIMATE THAT
SOME SCIENTISTS THINK COULD HAVE DOOMED ANY CHANCE FOR BUDDING LIFE TO
FORM OR EVOLVE. THE MOON ALSO HELPFULLY PULLS THE OCEAN'S TIDES, WHICH
SCIENTISTS SUGGEST MIGHT HAVE BEEN THE PERFECT PLACE FOR EARLY LIFE TO
BEGIN EVOLVING TO SURVIVE ON LAND.
F. EARTH’S _________ GIVES US A SOURCE OF GEOTHERMAL ENERGY, ALLOWS
CYCLING OF RAW MATERIALS, AND SETS UP A MAGNETIC FIELD AROUND THE PLANET
THAT PROTECTS US FROM RADIATION.
G. _________ SPHERE AROUND THE PLANET WHICH DEFLECTS THE SOLAR WIND AND
ALLOWS THE ATMOSPHERE TO REMAIN IN PLACE.
14. • IN A SEPARATE SHEET OF PAPER DO THIS: SOMETIMES WE JUST NEED A LITTLE REMINDER
TO HELP US CHANGE OUR HABITS.
HAVE YOU THOUGHT ABOUT WHAT YOU CAN DO AT SCHOOL AND AT HOME TO HELP THE
ENVIRONMENT AND HOW YOU CAN ENCOURAGE OTHERS TO CHANGE THEIR HABITS TO
CONSERVE AND PROTECT THE UNIQUE FEATURES OF EARTH IN ORDER TO MAINTAIN LIFE
ON EARTH?
