Welcome to class!
In today’s class, we will be talking about changes in nature. Enjoy the class!
Changes in Nature
Our environment is made up of living things and non-living things, they interact with themselves and experience various forms of change. In this lesson, we will be looking at changes that occur in nature, the meaning of change and the types of changes we have. We would also be looking at the differences between these types of changes and their examples.
Meaning of the concept of change
Change is said to happen when something becomes different from its normal form. Change happens when something or someone behaves differently from how they are known to behave. Changes take place in both living and non-living things.
Think of and share with friends the various changes that have happened in your life and the society in the last couple of months.
Types of change
There are two types of change, they are:
- Temporary change
- Permanent change
Temporary changes are changes that do not last. They are also known as reversible change meaning that the occurrence can go back to what it used to be. Examples of a temporal change are, turning of water to ice, turning of ice to water etc
Permanent change on the other hand is a change that lasts for a long time. Once it occurs, the substance cannot return to its original state. It is also known as irreversible change. An example of an irreversible change is the felling down of a tree.
In a table, arrange the activities below under two headings: temporary and permanent change:
- Making table from wood
- Ice turning to water
- Chameleon changing its colour to that of the environment
- Making shoe from animal skin
- The bowing away of papers by a fan.
Differences between temporary and permanent change
|Temporary change||Permanent change|
|Change is reversible||Change is irreversible|
|Change last for a short time||Change is permanent most times|
|A new substance is not formed||A new substance is often formed|
- What is change?
- Mention two types of change
- Give two differences between the types of change mentioned above.
In our next class, we will be talking about Changes in Plant. We hope you enjoyed the class.
