Teacher’s Activity Student’s Activity
A. Preliminary Activities 1. Prayer Good morning, Class! Peace and all Good!
Everybody stands up! Prayer leader please.
- Checking of Attendance Okay class, before take your seats, kindly pick up those pieces of trash and arrange your chair properly.
Good morning, Sir, Peace and all Good.
Classmates, are you ready to pray? (In the name of the Father......)
(Students will prepare their seats and surrounding for a more conducive learning atmosphere)
Also, kindly remove those unnecessary things on your table that is not connected to our topic for today.
Thank you!
Class, monitor who is/are absents today.
Okay, since nobody absent today let us give ourselves a “Good Job Clap!”
Very Good! Again, Good morning 9 Ephesians! 3. Monitoring of Assignment Did I give you an assignment last meeting?
Okay Class, please pass your paper in front.
B. Review/ Motivation Last meeting, we already discuss about the different features of Volcanoes, RIGHT?
Now, I will show a video clip and watch and listen carefully.
(Presenting a Video)
Okay Class, what did you see on the video?
Exactly!
What is the lesson you gain in the video presentation?
Very Good! How about the others?
Nice Idea! Without volcanoes, most of Earth's water would still be trapped in the crust and mantle. Early volcanic eruptions led to the Earth's second atmosphere, which led to Earth's modern atmosphere. Besides water and air, volcanoes are responsible for Land formation, another necessity for many lives forms.
C. Presentation of the Topic Now, we will proceed to our topic today. At the end of this lesson, you will be able to: 1. Describe the formation of a volcano
None, Sir.
G-O-O-D, JOB, GOOD JOB! GOOD JOB! (Repeat 3x)
Good morning, Sir.
Yes, Sir.
Yes, Sir.
(The students must watch the video)
Its all about the Volcanic Eruption.
Volcanos are certainly destructive, but without them, there would be no breathable atmosphere, oceans, land, or life
Sir, watching lava flow into the water is amazing. It’s like watching land being created right before your eyes. It’s really cool
role-playing, and etc. 3. Organization (40%)) Presentation should stay within the allotted time and avoid going off- topic or repeating information unnecessarily.
Please cooperate to your group I will give you 10 minutes for research and preparation.
Okay Class! Time is up!
Each group will be given 5 minutes to present your findings.
That was Amazing Class! Let us give our self a Good Job Class!
E. Application Now, I have here a picture of different types of volcano and you must identify and classify what types of volcano is.
(1st picture) (2md picture) (3rd picture) (4th picture) (5th picture) (6th picture) (7th picture)
Great Job Class!
F. Generalization Let’s have a recap for our topic today.
What is all about the Formation of Volcano?
Very Good!
How about the methods of formation of volcanoes?
Excellent!
And what is the types of Volcanoes?
Okay, Great!
Studying volcanoes is crucial because they are one of the most powerful and
- Subglacial Volcanoes
- Shield volcanoes
- Cinder cones
- Composite volcanoes
- Volcanic domes
- Supervolcanoes
- Submarine volcanoes
If the pressure of the magma is insufficient to cause volcanic eruption, it cools down over time and forms hard rocks, increasing the mass of the volcano.
Sir, the volcanic formation can be explained using the following methods: Formation by subduction and formation by distension.
Cinder Cones. Composite Volcanoes, Shield Volcanoes, Volcanic Domes. Supervolcanoes. Submarine Volcanoes, and Subglacial Volcanoes.
None, Sir.
unpredictable natural phenomena on earth.
Volcanic eruptions can cause significant damage to communities, susch as destroying homes, roads, and crops, and many more.
Overall, the study of volcanoes is essential in advancing our knowledge of the earth’s natural systems and developing sustainable solutions for living in a dynamic and changing environment.
Any questions and clarifications regarding to our topic?
VII. Evaluation
Teacher’s Activity Student’s Activity
I. Identification (13 points) Identify the difference between Formation by Subduction and Formation by distension.
The difference between the formation of volcanoes by subduction and distension is as follows: Subduction: Volcanoes formed by subduction occur along convergent plate boundaries, where two plates collide and one plate is forced beneath the other, or subducted, into the earth's mantle. The subducted plate melts and generates magma, which rises to the surface and forms a chain of volcanoes known as a volcanic arc. These volcanoes are typically composite in shape, with steep sides and explosive eruptions, and can produce hazards such as ashfall, pyroclastic flows, and lahars. Distension: Volcanoes formed by distension occur along divergent plate boundaries, where two plates move away from each other and the earth's crust is stretched and thinned. As the crust stretches, magma rises from the mantle and fills the gap, forming a fissure or crack in the crust. This magma then cools and solidifies to form a chain of volcanoes known as a rift zone. These volcanoes are typically shield in shape, with gentle slopes and effusive eruptions, and can produce hazards such as lava flows and volcanic gases.
