Class: Primary 4
Term: 3rd Term
Week: 6
Age: 9 years
Duration: 40 minutes
Subject: Basic Science & Technology
Curriculum Theme: Basic Science
Previous Lesson: Water – Chemical composition of water
Topic: Liquids – Meaning of liquid, Physical properties, Movement, and Examples of liquids

Content/Learning Area:

• Meaning of liquid
• Physical properties of liquids
• Movement of liquids
• Examples of liquids

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

• Cognitive Domain: Define what a liquid is and identify its physical properties.
• Affective Domain: Appreciate the importance of liquids in everyday life.
• Psychomotor Domain: Demonstrate the movement of liquids through practical experiments.
• Social Domain: Engage in group discussions about different examples of liquids.

Reference Materials:
The following resources were used in planning this lesson:

• 9 – Years Basic Education Curriculum
• Abuja Educational Resource Centre Scheme of work
• NAPPS National Unified Scheme of Work
• Online Information from Britannica Kids – Liquids
• Relevant Textbooks

Instructional Materials:
The teacher will teach this lesson with the aid of:

• Water
• Various liquids (e.g., oil, vinegar, juice)
• Clear containers
• Droppers
• Paper towels

Rationale for the Lesson:
Understanding the properties and behavior of liquids is crucial as they are a fundamental aspect of our daily lives. This knowledge helps us make informed decisions and understand various scientific phenomena.

Prerequisite/Previous Knowledge:
Students should have basic knowledge of states of matter, particularly solids and liquids, as introduced in previous classes.

INSTRUCTIONAL PROCEDURES:

Learning Area: Liquids – Meaning of liquid, Physical properties, Movement, and Examples of liquids

To deliver this lesson, the teacher will adopt the following steps:

Classroom Note:

Meaning of Liquid:

A liquid is a state of matter that flows freely and does not have a fixed shape but has a fixed volume. This means it can adapt to the shape of its container, or in other words means that liquids can pour and be poured.

Physical Properties of Liquids:

1. Liquids have a definite (defined) volume but no definite (defined) shape.
2. They can flow and take the shape of their container.
3. Liquids have surface tension; this causes the surface of a liquid to behave like a stretched elastic band which allows them to form droplets and bubbles.
4. Different liquids have different viscosities (thickness), making some flow more easily than others. For example, honey has a higher viscosity than water and flows more slowly.

Movement of Liquids:

Liquids move due to the free movement of their molecules. Unlike solids, the molecules in liquids are not fixed in place and can slide over each other. This characteristic allows liquids to flow and spread out when poured.

Examples of Liquids:

The following are examples of common liquids.:

1. Water
2. Milk
3. Juice
4. Oil
5. Blood
6. Vinegar

Lesson Evaluation:

To evaluate the learning, the teacher asks pupils to:

1. Define what a liquid is and provide two examples.
2. List three physical properties of liquids.
3. Explain why liquids move and give an example.

Note for teachers using my lesson plan:
Hi there, remember that I didn’t make this lesson plan with any particular class or teacher in mind and I tried as much as possible with my experience and expertise to deliver this plan in a standard and effective style utilizing the best strategy and methods. Nevertheless, you are free to customize the lesson content, teaching methods, timing, and pupil activities to suit your teaching style, pupils’ comprehension, curriculum, and resources available to you. Happy teaching!
