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 (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

1. Girl changes to woman
2. Boy changes to man

Changes in Nature 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.

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

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 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.

Meaning of Storage Device

Storage devices are computer hardware components that are used for storing data in electronic form. It is used to keep processed data. It can store text, images, video, audio, symbol, etc.

Storage devices are classified into two groups, these are:

1. Internal storage devices.
2. External storage devices.

Internal storage devices.

Internal storage devices are seen inside the computer. It is also called the primary storage device. Example of internal storage device is hard – disk.

External storage devices

External Storage Devices are seen outside the computer. They are connected with usb cable through the system unit.

Examples of external storage devices are flash drive, memory card, compact disk, external hard disk.

USES OF STORAGE DEVICES

1. Storage devices are used to keep data for temporarily or permanently.
2. Used in sharing file.
3. Storage devices are used to back up saved files.
4. They are used in transporting file from one storage device to another.
