Week One
Subject: Basic Science
Class: Primary Four
Week of the First Term: 1st Week
Topic: Changes in Nature
Sub-Topic: (i) Meaning of Change (ii) Examples of Change
Instructional Objectives
At the end of the lesson, pupils should be able to:
- Define the term “change” and explain its meaning in the context of nature.
- Identify and describe various examples of changes in nature.
- Demonstrate an understanding of how different changes occur through observation and discussion.
Entry Behavior
Pupils should already have a basic understanding of their surroundings and the concept that things around them can look different over time. They should be able to recognize and describe simple changes they observe.

Content
Introduction
Change refers to the process of becoming different or undergoing alteration. In nature, this can include physical, chemical, or biological transformations.
Body
- Types of Changes:
- Physical Change: Changes that affect the form or appearance of something without altering its chemical composition (e.g., melting of ice, tearing of paper).
- Chemical Change: Changes that result in the formation of new substances with different properties (e.g., rusting of iron, burning of wood).
- Biological Change: Changes related to the life cycle of organisms (e.g., growth of plants, development of animals).
Examples of Change:
- Growth of Plants: Seeds growing into plants and eventually flowering or producing fruits.
- Weather Changes: Changes in weather conditions such as sunny, rainy, or cloudy days.
- Change in State of Matter: Ice melting into water and water evaporating into steam.
Lesson Presentation
Step 1: Introduction
Start with a simple question: “Have you ever noticed how a seed grows into a plant?” Share a brief story or show a video clip of a plant growing from a seed to engage pupils. Connect this to the concept of change.
Step 2: Explanation
Define the term “change” and explain the different types of changes in nature using simple language and examples. Use visual aids to illustrate these concepts, such as images or diagrams of plants growing or ice melting.
Step 3: Demonstration
Conduct a simple experiment or demonstration, such as melting ice in different conditions (e.g., in sunlight vs. in a cooler environment) to show physical changes. Use visual aids to compare before and after states of various objects.
Step 4: Guided Practice
Divide pupils into groups and provide them with different examples of changes (e.g., pictures of different stages of plant growth, weather conditions). Have each group discuss and present what type of change is shown and why.
Step 5: Independent Practice
Give pupils a worksheet or activity where they identify and describe examples of changes they have observed in their own environment. Encourage them to draw or write about these changes.
Step 6: Feedback
Review pupils’ worksheets and activities, providing feedback on their understanding. Address any misconceptions and reinforce key points about the types and examples of changes.
Evaluation
Formative Assessment:
Observe pupils during discussions and activities to assess their understanding of the concept of change. Ask questions and provide immediate feedback based on their responses.
Summative Assessment:
At the end of the lesson, administer a short quiz or ask pupils to write a brief explanation of the different types of changes and provide examples of each type.
Summary/Conclusion
Summarize the key points of the lesson, including the definition of change, the types of changes (physical, chemical, biological), and examples from nature. Reinforce the importance of understanding changes in our environment.
Assignment
Define change.
Mention the examples of change.
