Rationale for the Lesson

The skin is the largest organ of the human body. Teaching its structure, functions, and care helps pupils understand how to maintain good hygiene and overall health.

Lesson Content/Board Summary

The Human Body

Structure and Parts of the Skin

The skin is the outer covering of the body and is made up of three main layers. Each layer has unique functions that protect and support the body.

The following are the main parts of the skin:

Epidermis – The outermost layer that protects the body from germs and injury.
Dermis – The middle layer that contains blood vessels, nerves, sweat glands, and hair follicles.
Subcutaneous Tissue – The innermost layer made of fat and connective tissues that store energy and protect internal organs.

Functions of the Skin

The skin performs important roles that help the body stay healthy and safe.

The following are functions of the skin:

It protects the body from germs, injury, and harmful rays of the sun.
It regulates body temperature through sweating.
It helps in the sense of touch, pressure, pain, and temperature.
It stores fat and water for the body.
It helps in excretion of waste products like sweat and salt.
It gives the body its color through pigments.

Care of the Skin

The skin needs proper care to stay healthy and free from infections. Good hygiene helps to prevent skin diseases and maintain freshness.

The following are ways to care for the skin:

Bath regularly with clean water and mild soap.
Use clean towels and personal bathing items.
Wear clean clothes always.
Apply cream or lotion to prevent dryness.
Protect the skin from too much sun.
Eat balanced diets rich in vitamins and water.
Avoid sharing sharp objects like razors to prevent infections.
Seek medical attention for skin diseases.
