LESSON CONTENT

CHANGES IN NATURE

What is change? Change is when something loses one’s or its original nature or it is an event that occurs when something passes from one state or phase to another.

When things are no longer in their normal form, it means a change has occurred. Living things and non-living things do experience changes.

Living things are things that have life-like animals (cats, dogs), Human beings (Male and female) while non-living things are things without life-like stones, tables, chairs chalkboards.

Examples of changes

1. Iron becoming rusty
2. Green leaves turning yellow
3. Melting of candle wax
4. Ice block changing to water
5. Girl changes to woman
6. Boy changes to man

Changes in Natures occur in two forms. These are: Temporary changes and Permanent changes

Types of changes

Temporary changes (Reversible Changes) are changes that happened for a short time and are reversible.

Temporary changes occur due to the change in position or condition in the Environment

Temporary changes occurs in living and non-living things.

Examples of Temporary changes

1. Water changes to ice block during low temperature.
2. Ice block changes to water when the temperature is raised.
3. Water becomes hot when heated.
4. Water becomes cold removed from fire after some time.
5. Chameleon changes their colours to their environment.

Permanent changes (irreversible Changes)

Once permanent change occurred the body or thing affected cannot be reversed to the way, it was before. That is, it is irreversible.

Permanent change also occurs in both living and non-living things.

Examples of Permanent changes

1. A child changes to an adult.
2. cassava turn to Garri
