The document provides instructions for a classroom activity where students will work in groups to solve rebus puzzles about volcanoes using mathematical equations. It includes a list of classroom rules and objectives for a lesson about volcano parts and types. Students will participate in activities to describe different volcano types through diagrams and identify volcano parts in pictures.

1. CLASSROOM RULES
1.Be on time.
2. Listen carefully while others are speaking.
3.Raise your right hand when you want to
speak.
4. Cooperate and participate in every activity.
5. Respect the ideas and opinions of your
classmates.

Each group will form a circle and all they have to do is to
analyse the picture and use a mathematical equation
which is the + and - .to answer the clueless word. Each
group will answer the hidden word using a pen and bond
paper. Whoever group will have the highest score will be
the winner.

11. VOLCANO

12. Objectives:
1.Describe volcano and it’s parts.
2.Illustrate and describe the different types of volcano.
3. Infer the importance of knowing the different types
of volcano.

13. Picture Perfect

14. Volcano
A Volcano is an opening in the Earth’s
crust through which lava, volcanic ash,
and gases escape.

15. Parts of a Volcano

16. Crater
Is the mouth of a
volcano and can be
found at the top of the
volcano

17. Craters- are formed by the outward explosion of rocks
and others materials from volcano. They are usually more
circular than calderas and usually much smaller than calderas.
Caldera- are formed by
the inward collapse of a
volcano during or after an
eruption.

18. Main Vent
A point in the Earth’s
crust where hot magma
has been able to rise
from the magma
chamber and reach the
surface.

19. Magma
Chamber
Large underground pool
of molten rock sitting
underneath the Earth’s
crust.

20. Lava
Magma
Magma- a molten rock
beneath the Earth’s crust
Lava- a molten rock that
reaches the Earth’s surface
during volcanic eruption.
Ash- is a mixture of rock,
mineral, and glass particles
expelled from a volcano during
a volcanic eruption.

21. Standards in Doing Group Activity
1. Read the instructions carefully.
2. Work quietly and cooperatively.
3. Observe time management and
cleanliness.

22. Activity 1: I am Who Say I
am
Group 1
Based on the picture you have, describe the
Composite Volcano using “Concept Map”
Group 2
Based on the picture you have, describe the
Cinder Cone Volcano using “Volcanic
diagram”
Group 3
Based on the picture you have, describe
the Shield Volcano using “Mind Mapping”

23. Types of a Volcano
Composite Volcano or Stratovolcano
Large, nearly perfect sloped structures
formed alternate solidification of both
lava and pyroclastic deposits.

24. Cinder Cone Volcano
• The simplest and most common type
of volcano.
• This is built from ejected lava
fragments. They have a steep slope,
wide circular crater.
Mt. Paricutin
in Mexico

25. Shield Volcano
• Very big in size, formed by the
accumulation of lava that oozes out
from the volcano. Since non-viscous
lava can flow freely. A broad, slightly
doomed structure that resembles a
warrior’s shield is formed.
Mauna Loa
in Hawaii

26. Let’s Do It
Direction: Complete the bubble map by supplying the importance of knowing
the different types of volcano of. You have only 3 minutes in doing the task.

27. Direction: Read the following questions carefully. Choose the
correct answer from the given choices.
1. What part of a volcano described as the molten rock that
reaches the Earth Surface?
A. Lava
B. Vent
C. Crater
D. Magma

28. 2. Which best describes volcano?
A. A natural opening in the Earth’s crust through which lava,
volcanic ash and gases escape.
B. A natural closing of the Earth’s surface which volcanic
materials are ejected.
C. A beautiful landforms that eject gases.
D. Destructive and erupt violently.

29. 3. Which of the following is NOT a type of volcano base on
shape?
A. Composite
B. Cinder Cone
C. Shield
D. Crater

30. 4. What type of volcano has broad summit areas, which makes it
resemble a warrior’s shield?
A. Composite
B. Vulcanian
C. Shield
D. Cinder

31. 5. Which of the following is not a parts of volcano?
A. Magma
B. Lava
C. Crater
D. Cinder Cone

32. Activity: Create Me!
Direction: Draw a model of a volcano on a bond paper. Put
colors using crayon or color pens. Label each part correctly.
