Detailed Lesson Plan In Grade 9 Science Time Frame: 60 minutes
I. Objectives At the end of the lesson, the students should be able to: 1. Explain what happens when different volcano types erupt and enumerate the factors that trigger volcanic eruption. 2. Demonstrate measures to undertake before, during, and after volcanic eruption. II. Content Standard The learners demonstrate understanding of the factors that affect climate, and the effects of changing climate and how to adapt accordingly. III. Performance Standard The learners should be able to participate in activities that reduce risks and lessen effects of climate change. IV. Learning Competencies
Explain what happens when different volcano types erupt and enumerate the factors that trigger volcanic eruption. (S9ES-IIIb-28)
Demonstrate measures to undertake before, during, and after volcanic eruption. (S9ES-IIIb-28)

Subject Matter Topic: “Volcanic Eruption” References: Grade 9 Science Links Textbook page 212-219 and, "Volcanic Eruptions", USGS, usgs/natural-hazards/volcano- hazards/volcanic-eruptions Materials: Power Point Presentation, Infinity Cubes, Construction Paper, Activity sheets, Handouts, Recitation Pass, TV, USB, Coke and Mentos, Boards and Chalk. VI. Procedures
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.
Also, kindly remove those unnecessary
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
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 Grade 9!
- 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 formation and different types of volcanoes, RIGHT?
Now, before we start. Let us have a short review about our previous lesson.
For our review let us have word scramble. Identify the word being described by the following statements and arrange the jumbled letters.
Let us start!
The first word is OTHOTPS, is a region of high volcanic activity not located at any plate boundary. The correct answer is?
That is right!
The second word is DUCNOUSTIB, it is a form of volcano that is dependent on the plates which form the top layer of the mantle.
Very Good! That is right!
The third word is NERDIC ONEC, is the simplest type of volcano in the world.
Correct Class! Next, OMDE VALA this is a rounded, steep-sided mound that is formed by small, bulging masses of lava primarily composed of their dacite or rhyolite.
Good Job Class! Good Work!
more conducive learning atmosphere)
None, Sir.
G-O-O-D, JOB, GOOD JOB! GOOD JOB! (Repeat 3x)
Good morning, Sir.
Yes, Sir.
(The students pass their assignments)
Yes, Sir.
Hotspot.
Subduction.
Cinder Cone.
Sir, that is Lava Dome or Volcanic Domes
Correct! The viscosity also described as the liquid’s thickness and stickiness. To more viscous and thicker the material is, the greater its resistance to flow.
Next, let us take a look at the different types of volcanic eruptions by this Infinity Cubes.
The first classifications of volcanic eruptions are Magmatic Eruption and it is composed of?
Correct!
And the Second type of Volcanic eruption which is Phreatomagmatic Eruptions that is composed of?
Amazing! And the last is?
Vulcanian, named after the Italian island volcano, which is also believed to be the home to the Greek god of fire, Hephaestus (Vulcan for Romans). It is an explosive eruptio0n that occurs when the pressure of entrapped gases in a relatively viscous magma becomes sufficient to blow off the overlying crust of solidified lava. Pelean, it occurs when a large quantity of gas, dust, ash, and lava fragments are blown out of a volcano’s central crater. Plinian, considered the most explosive and powerful of all eruptions.
Surtseyan, named after the island of Surtsey off the coast of Iceland. It is a kind of hydromagnetic eruption where magma interacts explosively. Submarine, type of volcanic eruption that takes place beneath the surface of water. Subglacial eruption, also called glaciovolcanism, which features the interaction between lava and ice often under a glacier.
The Phreatic Eruptions, also called steam-blast eruptions, are those driven by explosive expanding steam resulting from cold ground or surface water coming into contact with hot rock or magma.
ALERT LEVEL 0 means quite or no alert. ALERT LEVEL 1 means low level of volcanic unrest. ALERT LEV EL 2 means increasing unrest. ALERT LEVEL 3 means Magmatic Unrest. ALERT LEVEL 4 means Hazardous eruption imminent. ALERT LEVEL 5 means Hazardous Eruption in progress.
(The students should cooperate to their team and do the tasks)
(The students presented their activity) Here is a plan for a hypothetical volcanic eruption: Disaster Preparedness Plan for Volcanic Eruption Before the Eruption: Monitor volcano activity and heed warnings from
Good Job Class!
Also, we have the volcano alerts level given by the Philippine institute of Volcanology and Seismology (PHILVOLCS).
And these are?
Very Good Class!
E. Application Now, let us have activity. Activity: “Create Plan for a Volcanic Eruption”
I will group you into 3, and each group will create a disaster preparedness plan for a hypothetical volcanic eruption in their community, focusing on measures to undertake before, during, and after the eruption.
You will be given 5 minutes to discuss and make your Plan for volcanic eruption.
Okay class, please proceed to your respective groups.
Time is up!
Group 1 please proceed to the front to discuss your groups answer.............
authorities. Have an emergency kit with food, water, clothing, first-aid kit, and a battery-powered radio. Have a family communication plan to contact one another in case of evacuation. During the Eruption: Follow evacuation orders and leave the area immediately. Avoid low-lying areas and move to higher ground. Cover your mouth and nose with a damp cloth to avoid breathing in ash. Protect your eyes from ash by wearing goggles or glasses. After the Eruption: Wait for official authorities to give the all-clear to return home. Avoid driving in ash as it can clog engines. Use protective gear such as masks, goggles, and gloves when cleaning up ash. Clean roofs, gutters, and downspouts of ash to avoid structural damage. In addition to these measures, it is important to stay informed and follow the advice of emergency personnel and local authorities. Stay tuned to radio, TV, or social media for updates and instructions. Remember, the most important thing is to prioritize your safety and that of your family. By having a disaster preparedness plan in place before a volcanic eruption occurs, you can help protect yourself and those around you.
The Silica content of lava, temperature of the lava, and the gas dissolved in magma.
The magmatic eruptions composed of: Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian. The Phreatomagnetic Eruptions that composed of Surtseyan, Submarine, and Subglacial Eruptions. And the last type of volcanic eruptions is Phreatic Eruptions.
None, Sir.
eruption?
Any questions and clarifications regarding to our topic?
VII. Evaluation
Teacher’s Activity Student’s Activity
Assess the students learning through their group presentation and safety plan design.
(The student’s presentation in safety plan design)
VIII. Assignments
In a 1 coupon bond, research a volcanic eruption that occurred in the past 10 years and create a safety plan for the are affected.
IX. Remarks
Teacher’s Activity Student’s Activity
Class, always remember that this lesson can be applied to many areas of life, from preparing for natural disasters to planning for emergencies in our personal and professional lives. Everybody stands up for our closing prayer. Prayer Leader, please! Good Bye Class, Peace and All Good! Classmates, let us pray. In the of the Father.........
Good Bye Sir, Peace and All Good.
