The document outlines a lesson plan about Earth's subsystems. It includes: 1. Objectives to understand Earth's geosphere, hydrosphere, atmosphere, and biosphere subsystems and how they are interconnected. 2. Learning activities for students to list terms related to each subsystem, create models of the subsystems using recyclables, and identify ways individuals can help the environment. 3. An explanation of the subsystems - the biosphere contains life, the hydrosphere is the water mass, the atmosphere is the air layer, and the geosphere extends from the surface to the core.

1. Earth and earth systems

2. PRELIMINARY:
> CHECKING OF ATTENDANCE

3. I.OBJECTIVES
A. CONTENT STANDARD: The learners demonstrate an
understanding of the subsystems (geosphere,
hydrosphere, atmosphere, and biosphere) that make
up the Earth.
B. PERFORMANCE STANDARD:
The learners shall be able to conduct a survey to
assess the possible geologic hazards that your
community may experience.

4. C. LEARNING COMPETENCIES/OBJECTIVES:
Explain that the Earth consists of four subsystems, across
whose boundaries matter and energy flow. (S11/12ES-Ia-e-4)
D. SPECIFIC LEARNING OUTCOMES - THE LEARNERS
SHOULD BE ABLE TO:
At the end of the lesson, the learners will be able to:
1. Describe the characteristics of each subsystem
2. Realize that the subsystems are interconnected
3. Construct a model of the Earth’s subsystems using
recyclable materials

5. SUBJECT INTEGRATION
Contemporary Arts from the Regions - applies artistic skills
and techniques in the process of creation.
Reading and Writing - Evaluate a written text based on its
properties
Understanding Culture, Society, and Politics - examine human
responses to emerging challenges in contemporary societies

Application of 5 E-Learning Model

9. A. ENGAGE
Activity
Read and Write!
Strategy: Listing Items from a Text
Read the statement below and fill in the table with the needed answers.
Imagine walking along a rocky coast as a storm blows in from the sea. The wind
whips the ocean into whitecaps, and waves crash onto the shore. Before you
have time to escape, blowing spray has scrambled over the rocks to your car.
During the adventure, you have observed the spheres of the Earth.
List down the terms that are used in the statement that reflects to what made up
the Earth. Categorize them based on the following:

10. Air Water Land With Life

11. B. EXPLORE
 Activity 2: Your Face Looks Familiar
 Materials:
 Any clean recyclable materials
 Coloring materials/art materials
 Adhesives
 Procedures:
1. Using the recyclable materials, conceptualize your own model of the Earth’s
subsystem
2. Construct your earth’s subsystem model. Make sure the difference between
each sphere will be clear in your own model.
3. Present your model in the class

12. C. EXPLAIN
 System – A set of interconnected components that are interacting to form
a unified whole
 Earth’s Systems
1. Biosphere – includes all life forms on Earth
2. Hydrosphere – Dynamic mass of water that is continuously on the move
3. Atmosphere – is the thin gaseous layer that envelopes the lithosphere
4. Geosphere – extends from the surface to core

14. ELABORATE
Activity 3: My Environmental ‘To Do List”
Strategy: Tabulation
The human population has increased rapidly since the 1700s. For most of
human history, there were fewer than a billion people on Earth. In mid-
2009, 6.7 billion people inhabited our planet. Because of this, extensive
pollution is everywhere. As a student, what can you do to save not only a
particular system but the Earth itself?
Tabulate your answer on a separate sheet of paper. Copy the template
below

22. REMARKS:
Earth and Life Science is taken by learners four
times a week with one hour (1) per meeting.
