This lesson plan covers the formation and development of typhoons. It includes objectives, content understanding, learning resources, activities to engage students, and an assessment. Students will learn that typhoons form from warm, moist air rising over the ocean and condensing into clouds and rainfall. As more warm air rises to replace the air that formed the clouds, winds begin to circulate, potentially strengthening into a typhoon. The lesson uses videos, diagrams, and questions to help students understand the factors and step-by-step process of how typhoons form and develop.

1. LESSON PLAN In SCIENCE GRADE 8
(Darwin, Fleming, Hooke, Mendel, Pasteur)
I. OBJECTIVES
Content Standard
The learners demonstrate an understanding of:
the relationship between faults and earthquakes
the formation of typhoons and their movement within the PAR
the characteristics of comets, meteors, and asteroids
Performance
Standard
The learners shall be able to:
make an emergency plan and prepare an emergency kit for use at home and in
school
demonstrate precautionary measures before, during and after a typhoon, including
following advisories, storm signals, and calls for evacuation given by government
agencies in charge discuss whether beliefs and practices about comets, meteors, and
asteroids
Learning Competency
To explain how typhoon develops and how it is affected by landmasses and bodies of
water, specifically you are to:
1. explain how tropical cyclones form;
2. Explain how typhoons develop; 3. Describe the factors that affect a typhoon

(REVIEW)
Let us Recall! Activity 1
Directions: Label and draw a line to match the parts of the
layers of the atmosphere to its description.
1. the region of the Earth's atmosphere between the
troposphere and mesosphere. It has no clouds and is
marked by gradual temperature increase.
2. layer of the earth's atmosphere where site of all-weather
on the earth
3. the outermost region of the atmosphere of Earth or
another planet
4. the layer of the Earth's atmosphere in which
temperature decreases rapidly, located between the
stratosphere and thermosphere
5. the region of the atmosphere above the mesosphere in
which temperature steadily increases with height,
beginning at about 85 km/53 mi above the Earth's
surface

2. You have surely learned from your Grade 7
science that the TROPOSPHERE is a part of
the atmosphere where clouds are being
formed. This layer consists of water vapor,
carbon dioxide, methane, nitrous oxide, and
others. These gases block some heat that is
radiated back from the ground. Through the
process of conduction and convection, heat
is being transferred from one place to
another. It is also through convection that a
warm, moist air combines with cold air which
leads to the low-pressure system formation
where tropical cyclones are initiated.
ENGAGE
Show a video presentation on the activity.
Activity 2- What Kind of Air Causes the Formation of Typhoon?
Objective: After showing this activity, you will be able to describe what will happen when cold air and
warm air meet.
Guide Questions
1. Which color will be on top and in bottom?
2. Will the two colors separate or mix?
3. What do you think will happen when the cold air and warm air meet?
EXPLORE
Do the following activity. (Areas with frequent no answer in Module)
Activity 4- Dissecting of a Tropical Cyclone
Activity 5- When tropical cyclone becomes stronger!
Activity 6 Factors Affecting Typhoon
How tropical cyclones form into a storm?
Directions
:
complete the diagram of the formation
of
tropical cyclones with the words found in the
boxes.
The warmed air
continues to rise with
mist air from the ocean
taking its place creating
more wind
Condensation
releases heat into
the atmosphere
making the air
lighter
As the water
vapor rises,
it
cools and
condenses
liquid
droplets.
Water vapor
rises into the
atmosphere
Warm moist
air move over
the ocean

Guide Question
1. What are needed to create or form a tropical cyclone?
2. Base on the activity How can we relate formation of cyclone into Baking a
cake? (step-by-step process and ingredients needed to create a cake)
Teacher will also add: There are sequence needed to form a cyclone
same in Solving a mathematical problem we use sequence to correctly
solve it. We use PEMDAS .

3. EXPLAIN Presentation of answer through Group Chat
Provides Feed Back on the Activity based on their presentation
Teacher will show correct answers through video
Teachers discuss t0 formalize concept
ELABORATE
Ask Student questions for clarification.
1. What are needed for the cyclone to form?
2. Enumerate the process of cyclone formation.
3. How tropical cyclone turn into cyclone?
EVALUATE Directions: Read and answer the questions in the best way you can. Write the letter of your answer
and pm it to me
