Hello, young learners! Welcome back to Primary 4 Basic Science and Technology. In our previous lesson, we learned about Changes in Nature – Temporary and Permanent Change. Today, we’re going to learn about Changes in nature.
Objectives
By the end of this lesson, you should be able to:
- Explain the meaning of changes in nature.

Changes in Nature
What are changes in nature?
Changes in nature refer to the alterations or transformations that occur in the natural world. These changes can involve various elements of the environment, such as living organisms, substances, or the physical surroundings.
Types of Changes in Nature
There are two main types of changes in nature, and they are:
- Temporary changes, which are reversible and can be undone. For example, melting ice, folding paper, inflating a balloon.
- Permanent changes, which are irreversible and cannot be returned to their original state. For example, burning wood, cooking an egg, growing a plant.
Evaluation Questions
Now that you’ve learned about changes in nature, let’s see if you can answer these questions:
- What are the two types of changes in nature?
- Give an example of a temporary (reversible) change.
- Give an example of a permanent (irreversible) change.
- Can you think of other examples of changes in nature?
- Why is it important to understand the difference between temporary and permanent changes?
Conclusion
We’ve learned that changes in nature are all around us, and they can be either temporary or permanent. Understanding these changes helps us appreciate the world around us and make informed decisions in our daily lives.
