Grade Level & Section
Grade 10 G. Chaucer
Learning Objectives:
At the end of the lesson the learners should be able to:
1. Describe the properties of the layers of the earth; and
2. Tell the composition of the layers of the Earth.
ELICIT (Subject Integration: Araling Panlipunan, English)
MATERIALS
o Class will be divided into two groups. Students will identify the
different words inside the Earth. They will form and encircle the words
related to the layers of the earth.
Cut outs of
jumbled letters,
Inside the Earth.
o The teacher will instruct the mechanics of the activity.
: Learners will identify the different words in the puzzle, Inside the Earth
: Leaners will be given 5 minutes to form (encircle) and identify the
words.
: The first group who will have more words to identify will win.
ENGAGE
(Subject Integration: English: Oral-Communication skills, RASA-BASA)
o Students will have one representative to present their work and explain
what words they form from the puzzle, and its relation to the Earths
layer or to the lesson.
Output
o Each representative will read the words they form from the puzzle.

KEY CONCEPTS:
o Earth has three layers: Crust, Mantle, and Core.
o Earth’s crust is the outer layer of the Earth, similar to the skin of an
apple, and it is made up of both continental and oceanic crust which is
about 5-50km thick. Crust has a large percentage of Silicon (Si) and
Oxygen (O) which is about 90% of it.
o Earth’s mantle is the largest layer of the Earth and it is compose of
silicate rocks rich in Magnesium (Mg) and Iron (Fe).
o Outer core has a liquid layer and is the second largest layer. It is
compose of liquid Iron (Fe0 and Nickel (Ni).
o Inner core is a solid ball of metal, which is made up of solid Iron (Fe)
and Nickel (Ni).
o Seismic waves are used to determine which layers of the earth is solid
and liquid.
o Generalization (Integration of RASA-BASA)
o The teacher will present the summary of the lesson and the learners will
read aloud what is presented on the board.
o Crust is made up of continental and oceanic crust and is composed of Si
and O.
o Mantle is the largest layer of the earth and composed of silicate rocks
rich in Mg and Fe.
o Core is divided into two; Inner and Outer core and they are both made up
of Iron and Nickle.
o Seismic waves are used to determine which layers of the Earth are solid
and liquid.
EVALUATE
o Learners’ performance on the activity will serve as their evaluation.
o They will be rated as shown below.
