This document contains a detailed lesson plan for a Grade 10 Science class on plate tectonics theory. The objectives are for students to understand what causes tectonic plates to move, enumerate the factors, and realize the importance of convection currents underneath the earth. Students will perform an activity using paper and blocks to model plate movement. Convection currents in the earth's mantle are caused by heat from the core and drive the slow movement of tectonic plates along boundaries by pushing and pulling on them. Understanding plate tectonics helps explain geological events and prepares people for hazards like earthquakes and volcanoes.

2. A. Daily Routine
Teacher Student
Prayer
Class, please stand up and let us pray.
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.
( the students will pray)
Good morning Sir!
Thank you Sir.
None
Yes
B. Recall
Teacher Student
I give you 2 minutes to punish your song.
Time is up!
Let’s start, please listen and watch all
group.
Write the names of your members on
rubrics.
Good Job! All are prepared.
Give yourself “Sing Song Clap”
Thank you Sir.
((students will perform)
C. Motivation
Teacher Student
Use the beginning ” I believed that the
interior of the earth is …. Thank you!”
Start at the back.
(students will response)
D. Procedure
Teacher Student
The Plate Tectonic Theory provided an
explanation about the movement of the
lithospheric plates. This theory evolved
from the two former theories and was
developed during the first decades of the

3. 20th century.
The Earth’s lithosphere is divided into
several plates. As you have already
learned, these plates ride over the weak
asthenosphere. There are three types of
plate movements – separation of two
plates (divergent), collision of two plates
(convergent) and sliding past each other
(transform).
What facilitates the movement of the
plates?
Heat is produced in the core that
produces convection in the mantle. This
convection causes the plate to move
around.
To further understand this process, you
will perform the activity.
The two types of crust are continental
and oceanic.
The denser is oceanic.
E. Pre- Activity
Teacher Student
Last meeting I grouped you into three for
your activity today, can you please
proceed to your groupmates?
Where going to works the Activity 7 an
titled “Push me up and aside!”
In this activity, students will compute for
the rate of seafloor spreading.
Everyone, please read the objectives.
Instruction:
1. Get one manila paper and
pentelpen 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.
The objectives of this activity are:
 Explain what causes the tectonic
plates to move.
 Enumerate the factors that cause
tectonic plates to move.
 Realize the importance of the
creation of convection current
underneath the earth.

4. 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 your self “Boom Aw 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.)
In your answers, these are the possible
causes of tectonic activities. Again, this is
the processes/activities in the Earth’s
interior play a role in the processes along
Earth’s surface.
As a substance like water is heated, the less
dense particles rise while denser particles
sink. Once the hot less dense particles cool
down, they sink, and the other less dense
particles rise. This continuous process is
called convection current. This is exactly
what happens in the Earth’s mantle. The
hot, less dense rising material spreads out
as it reaches the upper mantle causing
upward and sideward forces. These forces
lift and split the lithosphere at divergent
plate boundaries. The hot magma flows out
of the mantle and cools down to form the
new ocean crust. The downward
movement of the convection current occurs
along a convergent boundary where the
sinking force pulls the tectonic plate
downward.
(The presenter presents their works and
asnwer the quide questions )

5. The convection currents rotate very slowly,
as they move and drag the plates along.
Because of convection current, the tectonic
plates are able to move slowly along the
tectonic boundaries, pushing each other,
sliding past each other and drifting away
from each other.
G. Generalization
Teacher Student
What is convection current?
Now that you understand what happens
inside the Earth and its effects on the
Earth’s surface, you should be able to
realize that the tectonic activities at the
surface just like volcanic eruptions and
earthquakes are inevitable. You should
view the Earth as a dynamic planet and
still the most fascinating planet for it
offers you a home that no other planet
can.
It is a current in the mantle because of the
heat from the inner layers of the Earth,
and is the force that drives the plates to
move around.
H. Valuing/ Application
Teacher Student
Importance, why need to discuss? Because for the preparedness and
awareness during earthquakes, tsunamis,
and volcanic eruption.
IV. Evaluation
Draw four (4) geologic events showing how they formed by the process of the
convergent boundaries.
V. Assignment
Explain the processes that occur along divergent boundaries and determine the
results of plates that are moving apart.
