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 a life like animals (cats, dogs) and human beings (Male and female) while non-living things are things without life like stone, 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. The girl changes to a woman
  6. Boy changes to a man

Changes in Nature Occur in two forms. These are: Temporary changes and Permanent changes

Types of changes

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

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

Temporary changes occur in living and non-living things.

Examples of Temporary changes

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

Permanent changes (irreversible Changes)

Once a permanent change occurs 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 into an adult.
  2.  cassava turn to Garri
  3. A dead person cannot live again.
  4. Trees are cut into planks to make furniture.
  5. Wood burnt into ashes.
  6. Cement mixed with sand and water to make a block.
