LEARNING OBJECTIVES 

By the end of the lesson, pupils should be able to:

1. Define matter.

2. Identify matter in their environment.

3. Classify matter into different forms.

4. Explain the meaning of an atom.

5. State that atoms are the building blocks of matter.

6. Give examples of matter around them.

ENTRY BEHAVIOUR

Pupils have previously learned about materials in their environment and different objects they see and use daily such as water, air, stone, and plants.

This lesson builds on that knowledge by helping pupils understand that all these materials are called matter because they have mass and occupy space, and that matter exists in different forms and is made up of tiny particles called atoms.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Stone

2. Water

3. Air-filled balloon

4. Book

5. Pencil

6. Chart showing solids, liquids, and gases

7. Pictures of atoms

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

INTRODUCTION

Everything around us is made of matter. The air we breathe, the water we drink, the books we read, and even our bodies are examples of matter. Matter occupies space and has weight, which makes it an important part of our daily lives.

Matter exists in different forms such as solids, liquids, and gases, and each form has its own characteristics. Scientists have discovered that all matter is made up of very tiny particles called atoms.

In this lesson, pupils will learn the meaning of matter, how to identify and classify matter, and understand that atoms are the fundamental building blocks of matter.

LESSON 1 – MEANING OF MATTER

Matter is anything that has mass (weight) and occupies space.

Examples of Matter:

• Stone

• Water

• Air

• Book

• Human beings

IDENTIFICATION OF MATTER

Matter can be identified because it:

1. Has weight (mass).

2. Occupies space.

3. Can be seen, felt, or measured.

4. Exists in different forms.

Examples

• A chair occupies space and has weight.

• Water occupies space in a container.

• Air occupies space inside a balloon.

LESSON 2 – CLASSIFICATION OF MATTER

Matter is classified into three main groups:

1. Solid

• Solids have a definite shape and definite volume.

• Examples: Stone, table, book, pencil

2. Liquid

• Liquids have no definite shape but have definite volume.

• Examples: Water, milk, oil

3. Gas

• Gases have no definite shape and no definite volume.

• Examples: Air, oxygen, cooking gas

Matter is anything that has mass and occupies space. It can be identified through its properties and is classified into solids, liquids, and gases with different examples.

LESSON 3 – ATOMS AS THE FUNDAMENTAL BUILDING BLOCKS OF MATTER 

An atom is the smallest particle of matter that cannot be seen with the naked eye.

Atoms as Building Blocks of Matter

Atoms are called the fundamental building blocks of matter because:

• All matter is made up of atoms.

• An atom is the smallest particle of matter.

• Atoms join together to form all substances.

• Atoms are the tiny building blocks that make up all matter.

• Everything around us (air, water, plants, animals, and objects) is made up of atoms.

Examples

• Water is made up of atoms.

• Air is made up of atoms.

• Plants and animals are made up of atoms.

• A table, chair, and book are all made up of atoms.

• Human beings and animals are made up of atoms.

Simple Illustration

Just as bricks are used to build a house, atoms are used to build all matter.

Atoms are the smallest particles of matter and are the building blocks of everything around us. All solids, liquids, and gases are made up of atoms joined together.

SUMMARY

In this lesson, pupils learned that matter is anything that has mass (weight) and occupies space.

They also learned how to identify matter through its characteristics, which include:

• Having mass (weight)

• Occupying space

• Existing in different forms

Pupils further learned that matter is classified into three main forms:

• Solid (e.g., stone, book, table)

• Liquid (e.g., water, milk, oil)

• Gas (e.g., air, oxygen, cooking gas)

Finally, pupils learned that atoms are the smallest particles of matter and are the fundamental building blocks of all matter. Everything around us, including water, air, plants, animals, and objects, is made up of atoms.

Pupils’ Activities: Pupils listen attentively and repeat the topic.

3. The teacher explains the meaning of matter as anything that has mass (weight) and occupies space.

Pupils’ Activities: Pupils listen and give examples of matter around them.

4. The teacher discusses how matter can be identified by its characteristics.

Pupils’ Activities: Pupils identify objects that occupy space and have weight.

5. The teacher explains the classification of matter into solids, liquids, and gases.

Pupils’ Activities: Pupils mention examples of solids, liquids, and gases.

6. The teacher displays charts or pictures showing the three classes of matter.

Pupils’ Activities: Pupils classify given materials into solids, liquids, or gases.

7. The teacher explains the meaning of an atom.

Pupils’ Activities: Pupils listen and ask questions where necessary.

8. The teacher explains that atoms are the smallest particles and the building blocks of matter.

Pupils’ Activities: Pupils mention examples of things made up of atoms.

9. The teacher asks oral questions to assess understanding.

Pupils’ Activities: Pupils respond to the questions.

10. The teacher summarizes the lesson and gives corrective feedback where necessary.
