1. EARTH AND LIFE
SCIENCE 11
Republic of the Philippines
Department of Education
REGION VII (Central Visayas)
Schools Division of Bais City
Q1/Week 1
2. CONTENT STANDARD
1. The formation of the universe and the solar
system
1. The subsystems (geosphere, hydrosphere,
atmosphere, and biosphere) that make up the
Earth
1. The Earth’s internal structure
3. PERFORMANCE STANDARD
Conduct a survey to assess the possible
geologic/ hydrometeorological hazards
that your community may experience.
4. MOST ESSENTIAL LEARNING
COMPETENCIES
1) Recognize the uniqueness of Earth, being the only planet
in the solar system with properties necessary to support
life. (S11/12ES-Ia-e- 3)
2)Explain that the Earth consists of four subsystems, across
whose boundaries matter and energy flow. (S11/12ES-Ia-e- 4)
5. LESSON OBJECTIVES
At the end of this lesson, the students can:
1) Describe the Earth’s Structure.
2) Identify the Earth’s Subsystem.
3) Identify the layers of the Earth’s Interior.
4) Identify the characteristics of earth that are necessary to support life.
5) Explain how the characteristics of the Earth sustain the needs of a
living organism.
6) Create a representation of the earth’s structure using materials that
can be found at home.
6. Preparatory Activities/ Daily Routine
1. Prayer
2. Checking of attendance
3. Distribution of Corrected Activity Sheets
10. Unlocking Activity (15 minutes)
Instructions:
1) The Class will be divided into three groups. Students, please
count-off and remember your numbers as this will be the
basis for our groupings.
1) Using a manila paper, the groups shall give their comparison
of the planets based on the following: a) mass, b) size), c)
density, d) mean temperature, e) gravity, f) length of day, g)
magnetic field, and atmosphere composition.
11. Unlocking Activity (15 minutes)
Instructions:
Group 1: Compare Venus and Earth
Group 2: Earth and Mars
Group 3: Venus and Mars
13. Unlocking Activity (15 minutes)
Guide Questions:
1) Among the three planets, which is the largest and the heaviest?
2) Compare the their mean temperature, what does it imply?
3) Looking into the Planets’ Composition of their Atmosphere, what could
be found in earth that is necessary to sustain human life? Recall from
your previous discussion on Biology and Chemistry.
4) Compare the measure of gravity. What could be implied based on the
data?
5) What could happen if the Earth would one day lose/change a specific
characteristic?
14. Unlocking Activity (15 minutes)
After completing the task, please post
your work on the chalkboard. Each group
shall present their observations and
comparisons within 2-3 minutes.
15. Overview of the Lesson
A. Earth’s Description
⮚ Structure
⮚ Formation
16. Overview of the Lesson
B. Earth’s Interior and Earth’s
Subsystem
⮚ Layers of Earth’s Interior
⮚ Earth’s Subsystem
C. The Characteristics that
makes Earth Habitable
17. The Planet Earth
With regards to structure,
Earth is considered as a
terrestrial planet.
Along with Mercury, Venus
and Mars as they have a core of
metal surrounded by rocks
(Webb, 2021)
18.
19. Earth’s Formation
Earth formed though this process of accretion about 4.6 billion
years ago.
The early Earth was very hot and had a molten, fluid composition,
with lost of geological and volcanic activity on the surface.

20. Earth’s Interior
The Earth is divided into three main layers. The dense, hot inner core
(yellow), the molten outer core (orange), the mantle (red), and the thin crust
(brown), which supports all life in the known universe.

22. Earth’s Subsystem
The earth system is
itself an integrated system.
It is subdivided into four
main components or
spheres: the geosphere,
atmosphere, hydrosphere
and biosphere. (SOAS, nd). https://eschooltoday.com/learn/interaction/
23.
24. A Special Planet: The Habitable Earth
What makes the Earth habitable?
It is the right distance from the Sun, it is
protected from harmful solar radiation by its
magnetic field, it is kept warm by an insulating
atmosphere, and it has the right chemical ingredients
for life, including water and carbon (Mickens, nd).
30. ASSESSMENT
For items 6-10. Create a concept map
showing the relationship or interaction of
the different subsystems.
