What is change?

Change is transformation.

Change is the movement from a former state of being to a latter state of being.

It is the end result of a process.

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 (cat, dog), Human beings (Male and female) while non-living things are things without life like stone, table, chairs chalkboard.

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

1. Boy changes to man

2. Day changes to night

3. Dough changes to loaves of bread

4. Catapillar changes to butterfly

5. Beans changes to moinmoin or àkàrà

Changes in Natures Occurs 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 they are reversible.The action can be done and undone or redone

Temporary changes occurs 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 change its colours to its environment

.
Permanent changes (irreversible Changes)

Once permanent change occurred the body or thing affected cannot be reverse 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

3. A dead person cannot live again.

4. Trees cut into planks to make furniture.

5. Wood burnt into ashes.

6. Cement mixed with sand and water to make block.

7. Burnt paper will turn to ashes and the ashes cannot turn back to paper

8. Anything that is burnt cannot be reversed back to its original condition.
