The learners demonstrate an understanding of: the relationship among the locations of volcanoes, earthquake epicenters, and mountain ranges. The learners shall be able to: 1. Demonstrate ways to ensure disaster preparedness during earthquakes, tsunamis and volcanic eruptions; 2. Suggest ways by which he/she can contribute to government efforts in reducing damage due to earthquakes, tsunamis and volcanic eruptions. S9ES –Ia-j- 36.4 Describe the internal structure of the earth
Specifically: 1. Describe the different layers of the earth in terms of its characteristics, properties and composition; composition; 2. Illustrate the composition of the earth by using symbols ; and 3. Relate the layers of the earth to the layers of the egg with its different composition.

Simply review the four layers of the earth by completing the ff.: 1. The thickest layer of of the earth is the _ _ N _ _ _. (Mantle) 2. The thinnest layer layer of the earth is the _ _ U _ _ . (Crust) 3. The innermost layer. _ _ _ _ R _ _ R _ (Inner Core) 4. The third layer starting from the outermost part of the earth. _ U _ _ _ _ _ R _ (Outer Core) It was already discussed in Module no. 1 t hat when an oceanic plate is involved in a plate boundary, it subducts to a deeper region known as the mantle. As it subducts, its leading edge melts. Based from this, emphasize that the mantle has a different temperature as compared to the crust where we live in. To introduce the lesson, show a portion of the film “The Core” wherein the

characteristic of the earth’s core is being showed. From this, tell the students that in today’s lesson, they will know whether the characteristics mentioned in the film are facts or fallacies.
Students will do Activity 2 “Our Dynamic Earth” LM p. 52-53
Students will present their output & ex plain the properties, characteristics, composition of the earth by referring to the symbols/grid used in the activity. Discuss also the answers to the guide questions of Activity 2. Ask the students to identify the composition of the layers of a boiled egg. Ask them also to compare it to composition of the earth’s layers. Summarize the lesson by asking the key concepts from the students: LAYERS OF THE Composition Properties Other EARTH Characteristics Crust Silicon, oxygen, Solid in phase Suitable for living aluminium, organisms calcium, sodium, potassium, iron, magnesium, titanium, hydrogen, granite & basalt rocks Mantle Silicon, oxygen, Solid & liquid Materials found iron and can flow easily, magnesium, hot high temperature rocks/molten materials Outer core Iron & nickel liquid High temperature Inner core Iron & nickel solid Has tremendous pressure For objective no. 1, use formative assessment: Describe the layers of the earth by the specifications that follow: 1. Mantle , composition _______________ 2. Crust , characteristic _______________ 3. Outer core, composition _____________ 4. Inner Core, property ________________ For the Activity, use the ff. rubrics: 5 pts. – all the symbols are drawn in its c orresponding layer 4 pts. – 1 of the symbols in the provided grid are not drawn in its corresponding layer 3 pts. – 2 of the symbols in the provided grid are not drawn in its corresponding layer 2 pts. – 3 of the symbols in the provided grid are not drawn in its corresponding layer 1 pt. – 4 or more of the symbols in the provided grid are not drawn in its corresponding layer

ATTACHMENT
ACTIVITY on MAKING MODEL OF THE EARTH
Procedures: 1. Divide the class into 10 groups. 2. Provide a reading material to each group. The reading material is about the layers of the earth. Use the underlined words in deciding on how to make the model.
READING MATERIAL:
The earth is made of four different layers: crust, mantle, outer core, and inner core. 1. The crust is the outer most layer. The temperature ranges from 0oF on the surface to 1600oF below. Its thickness is about 3-5 miles under the oceans and 25 miles under the continents. The crust is relatively cold compared to the other Earth layers so therefore it can crack, causing earthquakes. It is made up of many pieces, called plates which float on the mantle located below the crust. Composition is common rock silicate compounds. 2. The mantle is located below the crust. The temperature is 1600oF at the top and 4000oF near the bottom. It is approximately 1800 miles thick. The mantle is the largest layer of Earth and is composed of very hot, dense rock. This layer of rock moves like thick, hot asphalt due to the extreme temperature differences between the top and bottom of the layer. This movement causes the plates in the crust to move. Composition is iron, magnesium, aluminum, silicon, oxygen, and silicate compounds. 3. The outer core is the next layer. The temperature is 4000oF to 9000oF and its thickness is 1400 miles. The outer core is in liquid form because the material is so hot. It is composed of liquid iron and nickel. As the Earth rotates the liquid core spins creating the Earth’s magnetic field. 4. The inner core is the center most layer. The temperature is around 9000oF. It is approximately 800 miles thick and is made of solid iron due to extreme pressure. The inner core does not move but vibrates in place. The pressure on the inner core is 45,000,000 pounds per square inch which is 3,000,000 times more than air pressure.
3. Based from the reading material, each group will make a model of the ear th showing each layer. 4. Present the model to the class.
