 V. Routine Activities
The teachers will greet the class, check their attendance, ask them to clean their
surroundings, arrange their chairs properly, and keep all other devices or materials
unnecessary for the class.

VI. Preparation
In this activity, the teacher would demonstrate actions from the lyrics of Mr.
Comerford’s Plate Boundary Rap. Students would be asked to stand up and follow what
the teacher is doing.The goal of this activity is to set the mood of the students while
introducing them to the topic about plate tectonic boundaries.

Lyrics from Mr. Comerford’s Plate Boundary Rap:

Plates move as slow as your fingernails grow

And as Wegener helped discover
Boundaries that:
Converge come together
Diverge pull apart
And transform slide past each other

Chorus (repeat 3x):

Convergent: Collide (two hands forming a gate-like structure )
Divergent: Divide (two hands forming a gate-like structure, but opened )
Transform Tectonic: Slide (two arms sliding from each other then forming a rapper pose)

VII. Presentation
A. Activity
Modeling Tectonic Plates Activity
In this activity, students will be shown two models that illustrate tectonic plate
movement. The first model would be an orange representing the earth. The orange peel
will be carved into little plates that represent the earth’s tectonic plates that float on top of
the mantle. The students will then be asked what happens when the pieces of orange skin
are pushed together and pulled apart. The second model would be wooden blocks that have
been separated diagonally. Students will then be asked what is observed when both wooden
blocks are pushed together, pulled apart, and when the wooden block’s sides are slid back
and forth together.

B. Analysis
The goal of the models is to visualize what happens when tectonic plates are moved
in several ways. The first model, the orange, represents the earth while its peel represents
 the earth’s tectonic plates and how it fits over the earth’s surface. When carved orange
skins are pushed together it will push on top of each other showing mountain building and
when pulled apart it shows a divergent boundary where the plates separate on the earth’s
surface. The second model which was the wooden blocks, represent plate boundaries.
When these blocks are pushed together a thrust fault is represented, when pulled apart it
represents a normal fault, and when the sides are slid together it represents a strike-slip
fault.

C. Abstraction
The teacher will start the discussion by telling the students that the activity they
have done has a relationship with the topic for this day. Just like the orange peel in the
activity, the theory of plate tectonics tells that the earth’s lithosphere is divided into eight
major plates that are moving constantly at a rate of centimeters per year. These plates have
edges where they meet each other called plate boundaries.
Today’s lesson is about the three types of plate boundaries and the effect of the
movements along these boundaries. The plate boundaries can be divergent, convergent,
and transform.

Divergent Plate Boundary

Divergent boundaries form by
splitting apart segments of continental crust
along rift valleys. There are boundaries
between plates of lithosphere namely
oceanic ridges and subduction zones. When
the oceanic lithosphere separates along the
oceanic ridge, a gap is created. This gap is
then filled by magma that arises from the
asthenosphere. As it cools down and
solidifies, it creates a new oceanic Figure 1.1. Africa with its linear lakes
lithosphere. Source:https://courses.lumenlearning.com/sunygeophysical/cha
pter/tectonic-plate-boundaries/
Shallow earthquake can occur along
with volcanoes along the rift areas as divergence occurs. As this begins, a valley can be
developed and over time, it can fill up with water creating linear lakes. If this process
continues, a sea can be formed and finally an ocean.
Moreover, youthful divergent boundaries are represented by narrow oceans, while
the long-lived oceanic basins are represented by wide oceans.
In Figure 1.1, notice the lakes that look linear on the east part of Africa, these are
the results of the movement of divergent boundaries.
 Convergent Plate Boundaries
Convergent boundaries are those that
collide with each other, resulting in destruction of
oceanic lithosphere at subduction zones.
Convergent boundaries can be ocean-to-continent
convergence, oceanic-to-oceanic convergence, or
continental-to-continental convergence.
When the oceanic lithosphere collides with
continental lithosphere, an oceanic plate which is
denser than continental one, will descend into a
Figure 1.2. Convergent boundaries: subduction zone. Usually, continental plates are
(from top to bottom) ocean-to- not destroyed during this convergence. This
continent convergence, oceanic-to -
collision can result in formation of deep oceanic

trenches, deep mountain roots, extensive

subduction zones.

When two oceanic plates collide, the
older plate which is the denser one, will subduct into the mantle. An ocean trench is the
mark that signifies the location where the plate is pushed down into the mantle. Trenches
often lie adjacent to chains of islands (island arcs) formed by magma from the subducted
plate.
In the case of the collision of two continental plates, instead of subduction, the two
plates buckle up to create large mountain ranges. This collision creates intense folding and
faulting rather than volcanic activities. Example of this is the Himalayan Mountains which
marks the boundary between Indian and Eurasian plates.

Transform Plate Boundary

Transform boundaries join sections of
convergent and divergent sections. It is where two
plates slide past parallel to each other, without
creating a gap or without being consumed. As the
plates rub against each other, huge stresses can
cause portions of the rock to break, resulting in
earthquakes. Places where these breaks occur are
called faults. Example of it is the San Andreas Fault
where the Pacific plate is grinding past on North

America plate at a rate of three inches per year. Fault between the Pacific plate and North

 D. Application
The earth is like a jigsaw puzzle containing 20 tectonics plates as its pieces.
Understanding the movement of these tectonic plates is important because these
movements cause earthquakes, volcanic eruptions, and the likes. To be familiarized with
this information will not stop natural calamities from happening but can prevent the hazards
of living. Moreover, this will help students understand how mountains are formed and will
help them tell the cause of the gaps within the earth's surface. In places around the world
there are many visible rock formations, knowing about plate boundaries will help students
to understand how these rock formations came to happen.

VIII. Generalization

Plate boundaries are the edges where two plates meet. It constantly has slow motion
measured in rates of centimeters per year. There are three types of plate boundaries:
divergent, convergent, and transform plate boundaries.
Convergent boundaries are those that collide with each other, which results in
mountain and volcano formation. It can also create trenches and island arcs. Moreover,
divergent boundaries form by splitting apart or by dividing segments of continental crust
along rift valleys. It results in formation of mid-ocean ridges, a rift valley, or a submarine
mountain range. Lastly, transform boundaries, where two plates slide past parallel to each
other, join sections of convergent and divergent sections. As these plates rub against each
other, huge stresses can cause portions of the rock to break, releasing an earthquake.

Students will then be asked to stand up to listen and dance the whole song of Mr.
Comerford’s Plate Boundary Rap to cap the lesson on a high note.
