Lesson Duration: 45 minutes
Week & Period: Week 19, Period 4
Topic: Our Earth and Its Composition
Sub-topic: Meaning of Earth; Components of the Earth (rock, soil, air, water)
Learning Objectives
By the end of the lesson, students should be able to:

  • Describe the Earth in simple words.
  • Identify and name the main components of the Earth: rock, soil, air, and water.
  • Recognize these elements in their immediate environment.

Previous Knowledge
Students already know:

  • Basic understanding of surroundings.
  • Names of common objects in the environment.

Instructional Materials

  • Pictures of Earth and its components
  • Real examples: rocks, soil, water, air (balloon)
  • Chart paper and markers

Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter) Time: 5–10 minutes

  • Teacher asks: “What is the Earth?” “Can you name things you see around you?”
  • Students share ideas about land, water, and air.

B – Building Knowledge (Main Lesson Body)

Time: 25–30 minutes

Learners’ Activities (Expanded):

  • Teacher introduces the Earth as the place where humans, animals, and plants live. Teacher explains that the Earth is made of rocks, soil, air, and water.
  • Students observe real samples: a cup of soil, a small stone/rock, a bowl of water, and a fan blowing air. Teacher asks: “What do you see? What do you feel?”
  • Teacher shows pictures or charts of Earth’s surface (mountains with rocks, rivers with water, farms with soil, and sky with air).
  • Students identify examples of these components around the school compound:
    • Rocks (stones by the path, gravel).
    • Soil (playground, garden).
    • Air (moving leaves, flying papers).
    • Water (taps, buckets, puddles).
  • Teacher demonstrates that air is invisible but present everywhere by blowing a balloon or waving a paper in front of a fan.
  • Students work in pairs to draw simple pictures of the Earth showing land (soil/rocks), water, and air (sky). They label their drawings.
  • Teacher guides a sorting activity: students classify pictures into “rock,” “soil,” “air,” and “water.”

Assessment Checks:

  • Oral questions:
    • “Which component do we breathe?” (Air).
    • “Which one can we drink?” (Water).
    • “Which one do we walk on?” (Soil and rocks).
  • Peer discussion: Students share one example of soil, rock, air, and water they saw around them.
  • Quick “point and name” activity: Teacher shows an item or picture (stone, cup of water, leaves moving) and students call out the correct Earth component.

Notes (Expanded & Detailed):

  • The Earth is made up of four main components:
    • Air – We cannot see it, but we breathe it to stay alive. It is everywhere around us.
    • Water – Found in rivers, wells, ponds, oceans, and rain. All living things need water to survive.
    • Soil – The soft part of the land where plants grow. Soil gives us food and supports trees and crops.
    • Rocks – Hard parts of the land. Some are big like mountains, others are small like pebbles. Rocks can break into soil.
  • Together, these components make life possible on Earth.
  • Key reminder for pupils: Without air, water, rocks, and soil, living things cannot survive.

C – Consolidation (Conclusion & Assessment) Time: 5–10 minutes
Summary:

  • Recap Earth’s components and their examples.

Evaluation Method (Expanded):
• Exit slip/quiz: Students list the 4 components of the Earth.
• Teacher will collect slips and provide oral feedback.
Assignment (Expanded):

  • Students draw a picture showing rocks, soil, water, and air at home.

Follow-up Activity:

  • Nature walk to observe Earth’s components around the school.

Differentiation / Inclusive Strategies

  • Use tactile materials for students with visual impairments.
  • Pair students for peer learning.
