1. PLANET EARTH and
ITS PROPETIES TO SUPPORT LIFE
Recognize the uniqueness of Earth being the only planet in
the Solar System with properties necessary to support life.

2. Before we start with the lesson,
write down your idea on the
question:
Why Earth is the ONLY planet in
Solar System that can support life?

4. Venus Eart
h
Mars
Observe our neighbor planets – Venus and Mars. What are the similarities and differences of these planets compared to Earth? Even though they are near our
planet, life is not possible in Venus and Mars. One explanation is somehow related to the story of “Goldilocks and the 3 Bears”. Are you familiar with the story?

Goldilocks Zone

12. Goldilocks Zone
 or habitable zone
 the range of distance
with the right
temperatures for water
to remain liquid.

13. “JUST RIGHT”EARTH 13
 the third planet from the Sun and fifth largest planet in the Solar
System
 a terrestrial planet located in the Goldilocks zone (habitable zone)
 has unique physical and chemical characteristics compare to other
neighboring planets
 the only habitable planet or planet known in the Solar System that
can support life
Earth’s fundamental conditions are
“JUST RIGHT” to support life.

14. Factors that Makes
Earth Habitable
14

15. Factors that Makes Earth Habitable
TEMPERATURE 15
 Influences how quickly atoms & molecules
move
 Allows liquid water to exist on Earth’s surface
which is favorable to life.

16. 16
Factors that Makes Earth Habitable
WATER
 Dissolves & transports chemicals
within and to and from a cell
 The existence of
water in three phases
is very essential to
Earth’s diverse
ecosystem.

17. 17
Factors that Makes Earth Habitable
ATMOSPHERE
 Traps heat, shields the
surface from harmful
radiation, and provides
chemicals needed for
life, such as nitrogen and
carbon dioxide.
 It regulates the balance
of water, oxygen and
carbon dioxide

18. 18
Factors that Makes Earth Habitable
ENERGY from the SUN
 Light or chemical energy is used by organisms to run
their life processes such as the process of
photosynthesis used by producers like plants.

19. 19
Factors that Makes Earth Habitable
NUTRIENTS
 Used to build and maintain an organism’s body.

20. 20
Factors that Makes Earth Habitable
MAGNETIC FIELD
 a planet requires a rapidly
rotating magnetic field to
protect it from flares from
nearby stars and from
harmful radiation

Is there a possibility
that there are
OTHER PLANETS
that are habitable
aside from Earth?

On this activity, you are expected to learn on what
makes planet Earth habitable or has the ability to
support life. The Web (Internet) contains a vast of
information where you can learn more about our
planet. So, here’s a WebQuest activity for you.
Here are the simple steps to complete this
WebQuest:
1. read the question
2. follow (click or search) the link
3. read the article then write down the answers to
the questions you’ll find from the link.

25. 1) Is there a possibility that there are other planets that are habitable
aside from Earth? Why? Why not? (https://exoplanets.nasa.gov/what-
is-an-exoplanet/how-do-we-find-life/)
2) What makes a planet habitable?
(https://seec.gsfc.nasa.gov/what_makes_a_planet_habitable.html)
3) Why life is not possible on our neighbors planets like Venus and Mars?
