1) The document is a detailed lesson plan for a Grade 10 Science class about the composition of the Earth's interior, specifically focusing on the characteristic of plasticity in the asthenosphere layer. 2) The lesson plan outlines the objectives, references, materials, procedures, and evaluation for a lesson that uses demonstrations and activities to help students understand how the asthenosphere's ability to flow slowly influences the movement of tectonic plates. 3) Students will perform demonstrations using mixtures like cornstarch and water to simulate the plasticity of the asthenosphere, present their findings, and relate its properties to real-world tectonic plate movement before creating a song about the topic for evaluation.

2. Greetings
Good morning class!
Classroom Conditioning
Kindly arrange your chairs and pick up
those pieces of paper around you.
Okay, please be seated.
Checking of Attendance
Danica, is there any absent for today?
Very good!
Checking of Assignment
Did I give you any assignment
yesterday?
Exchange your paper to your seatmate.
Good morning Sir!
Thank you Sir.
None
Yes
B. Recall
Teacher Student
I give you 2 minutes to punish your talk
show.
Time is up!
Let’s start, please watch all group.
Write the names of your members on
rubrics.
Good Job! All are prepared.
Give yourself “Oppah Clap”
Thank you Sir.
((students will perform)
C. Motivation
Teacher Student
I have here a game an titled “Pinoy
Henyo”
Did you know the game?
I have here a UNO card, please get one
and pass faster.
All get red cards, proceed at the back.
Blue cards, in left side and green cards, in
the right side.
Instruction
1. Choose 3 representatives per
group.
2. The allotment time is 1 minutes
and 30 seconds to cope up the
Yes, Sir.
(students will go to the proper places)

3. word.
3. The faster time is the winner and
will get a three points that will be
added to the quiz.
Words:
Soil
Land
Sand
I think you are now motivated.
(students will perform this game)
D. Procedure
Teacher Student
I have here a boiled egg, represent the
layer of the earth.
Anyone can cut the egg into two?
The shell is a crust.
White part is a mantle.
And the egg yolk is the core.
I use the cracked shell to represent the
lithosphere and soft butter to represent the
asthenosphere.
(student) can you please slide the shell
cracks over the soft butter.
Anyone idea how the lithosphere ride
over the asthenosphere?
“How will the mixture of cornstarch and
water react? Will it act as liquid, solid or
gas?”
To elaborate let’s now perform the
activity.
(student will cut the egg into two)
(student will slide the shell)
The ability of the asthenosphere to flow
slowly is termed as plasticity.
E. Pre- Activity
Teacher Student
Were going to works the Activity 3 an
titled “Demonstration: Simulating
Plasticity”
Everybody, please read the materials and
procedures.

4. Instruction:
1. Get one manila paper and pentel
pen for your activity.
2. Cooperate and collaborate with
your groupmates.
3. Your time is 10 minutes to study,
to analyze and to answer the guide
questions.
4. Choose two to three presenter of
your activity.
5. Your score for this activity is based
on rubrix.
Let’s start !
F. Post Activity
Teacher Student
Time is up!
Please, paste your activity works on the
board.
Give yourself “Shake Clap”
Let’s start group 1.
I want to hear the next group, group 2.
Present your work group 3.
(The teacher will add information while
the presenters presents their works.)
(The presenter presents their works and
asnwer the quide questions )
G. Generalization
Teacher Student
What is plasticity?
How does the plasticity of the Earth’s
mantle influence the movement of the
lithospheric plates?
The ability of the asthenosphere to flow
slowly.
Since the mantle is capable of flowing
slowly, it carries and facilitates the
movement of lithospheric plates above it
as it moves.
H. Valuing/ Application
Teacher Student
For real life situation, how you relate to
this topic?
(students will answer based on his/her
opinion)

5. IV. Evaluation
Create a song about this topic, maximum 3-4 minutes and your score is based
on rubrics. It will be present tomorrow.
V. Assignment
Research the details about the first layer of the earth which is crust.
