Science Concept
Two types of seismic waves are body
waves and surface waves. Body
waves travel through the inner layers of the planet, while surface waves do so
only on the surface
III. Procedure
A. Premilinary Activities

Routine
a. Prayer
b. Checking the attendance
2.
Review
Before the class is forlamy start, teacher will ask some student about
the last topic.
“where does diamonds form?
3.
Motivation
The class will be divide into three groups. I will give each group a
jigsaw puzzle, but only two members of the group is allowed to arrange the
puzzle. The other members will standing in one line. When the two members are
done with the puzzle, one will stand and go to the last member of the group and
wispher what inside the puzzle. While passing the message the other group
member will stay silent and when it reach the first member she/he will write
the answer on the board. The first group who win finish the game will be
considered as the winner.
IV. Presentation of Lesson
The teacher will ask the student on what is
their idea about the topic for today according to the terms in the activity.
V. Development
of The Lesson:
The
teacher will use Power Point and video as the strategy of the lesson.
The
seismic waves are detected by highly sensitive instruments called seismometers and recorded by
seismographs.
Two types of seismic waves are body
waves and surface waves. Body waves travel through the inner layers of the
planet, while surface waves do so only on the surface.
Body Waves
During an earthquake, two types of
body waves radiate an all directions: the P-Waves, shown as straight linesin
figure 1-5 and the S-waves, represented by the wavy lines.
The P-waves, also known as primary
waves, are the first to be felt on the Earth’s surface. They travel at speeds
between 1.5 and 8 kilometers per second. P-waves are compressional waves; they
shake the ground back and forth in the same and in opposite direction through
which they move. P-wave pass through solid sections of the Earth but are
refrected or bent when they travel through liquids.
The S-waves, also known as secondary
waves, are transverse waves, which are left in an up-and down motion
perpendicular to the direction of the wave. S-waves do not travel through
liquids. It is for this reason that the outer core was found to be liquid. The
S-waves travel about 60% to 70% more slowly than P-waves.
Surface Waves
There are two types of surface waves,
Love waves and Rayleigh waves. Love waves are the fastest type of surface
waves and move the ground from side to side. They were named after the British
geophysicist and mathematician, Augustus Edward H. Love, who worked on mathematical
models to demonstrate the protogation of surface waves and the structure of the
earth. Rayleigh waves move in a circular manner, similar to rolling on the
ground, and cause buildings to heave up and down and side to side. There waves
were named after John William Strut, also known as Lord Rayleigh, whose
mathematical modeling, predicted the possibility of this type of waves.
Rayleigh waves, with their rolling circular motion under the gorund, account
for the greater devastation during an earthquake.
VI. Generalization
The
Teacher will ask the following:
1.
What is
the different about The P-Waves and The S-Waves?
2.
Who will
explain the different of body waves and sueface waves?
VII. Evaluation :
True
or False
Write
TRUE if the statement is correct and wrire FALSE if the statement is incorrect.
1.
Love waves are the fastest type of surface waves and move the ground from side
to side.
2.
P-waves are tranverse waves which are felt in an up-and-down motion
perpendicular to the direction of the wave.
3.
S-waves travel about 60% to 70% more slowly than P-waves.
4.
Rayleigh waves were named after John William Strutt.
5.
Body waves are felt toward the end of an earthquake and are responsible for
greater damage.
Answer key:

I. Objectives:
a. define Pangea the supercontinent;

discuss
the force which broke apart the continents millions of years ago;
c.
recognize
alferd wegeneris uriousity led to the idea of pangea,; and
d.
create

II. Subject Matter:
A. Topic: “Pangea: The Supercontinent”
B. Material: video, pictures, DLP, powerpoint
presentation
C. Science Concept
The Earth, which has seven separate continents, began as one huge mass
of land called Pangea. The term Pangea comes from the Greek root pan, which
means “all” and gaea,”earth”. Pangea thus mean “all of earth” or “all lands.”
The waters surrounding Pangea was called Panthalassa, which in Greek means “all
seas”.

the last topic.
“who would like to remind us what was our previous topic about?

Motivation
The class will be divide into three groups. I will give each group a
puzzle, after that the student must to connecting the picture with the topic
for today.

V. Development
of The Lesson:
Pangea was surrounded by a global ocean called Panthalassa,
and it was fully assembled by the Early Permian Epoch (some 299 million to 273 million years ago). The
supercontinent began to break apart about 200 million years ago, during the
Early Jurassic Epoch (201 million to 174 million years ago), eventually
forming the modern continents and the Atlantic and Indian oceans. Pangea’s existence was
first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning “all the Earth.”
During the Early Permian, the
northwestern coastline of the ancient continent Gondwana (a paleocontinent that would
eventually fragment to become South America, India, Africa, Australia, and Antarctica) collided with and joined the southern
part of Euramerica (a paleocontinent made up of North America and southern Europe). With the fusion of the Angaran craton (the stable interior portion of a
continent) of Siberia to that combined landmass during
the middle of the Early Permian, the assembly of Pangea was complete.
Cathaysia, a landmass comprising the former tectonic plates of
North and South China, was not incorporated into Pangea.
Rather, it formed a separate, much smaller, continent within the global ocean
Panthalassa.
The mechanism for the breakup of Pangea
is now explained in terms of plate
tectonics rather
than Wegener’s outmoded concept of continental drift, which simply stated that
Earth’s continents were once joined together into the supercontinent Pangea
that lasted for most of geologic time. Plate tectonics states that Earth’s
outer shell, or lithosphere, consists of large rigid plates that
move apart at oceanic ridges, come together at subduction
zones, or
slip past one another along fault lines. The pattern of seafloor
spreading indicates
that Pangea did not break apart all at once but rather fragmented in distinct
stages. Plate tectonics also postulates that the continents joined with one
another and broke apart several times in Earth’s geologic history.
The first oceans formed from the breakup, some 180
million years ago, were the central Atlantic Ocean between northwestern
Africa and North America and the southwestern Indian Ocean between Africa and
Antarctica. The South Atlantic Ocean opened about 140 million years ago as
Africa separated from South America. About the same time, India separated from
Antarctica and Australia, forming the central Indian Ocean. Finally, about 80
million years ago, North America separated from Europe, Australia began to rift
away from Antarctica, and India broke away from Madagascar. India eventually collided
with Eurasia approximately 50 million years ago, forming the Himalayas.
During Earth’s long history, there probably have been
several Pangea-like supercontinents. The oldest of those supercontinents is
called Rodinia and was formed during Precambrian time some one billion years ago. Another Pangea-like
supercontinent, Pannotia, was assembled 600 million years ago, at the end of
the Precambrian. Present-day plate motions are bringing the continents together
once again. Africa has begun to collide with southern Europe, and the
Australian Plate is now colliding with Southeast Asia. Within the next 250
million years, Africa and the Americas will merge with Eurasia to form a
supercontinent that approaches Pangean proportions. The episodic assembly of
the world’s landmasses has been called the supercontinent cycle or, in honour of Wegener, the Wegenerian cycle (see plate tectonics:
Supercontinent cycle).
