CONTENT: 1. Structure, functions, care and grooming of the hair.  

  1. Structure, functions, care and grooming of the eye.

 

Structure, functions, Care and grooming of the hair:

Human hair is mostly found on the head. It is one of the beautiful assets on a human body; it makes an individual attractive when it is well cared for.

 

The structure of the hair:

Hair grows from a hair pit/narrow tube inside the skin called follicles. Each follicle has at its side tiny oil glands, which produces oil. The oil helps to lubricate the hair and keep the skin around it soft and smooth.

 

Types of Hair:

Hair comes in different colours, textures, shades, and length depending on race, food, health condition, ageing and care.

We shall however discuss the types of hair under:

  1. Dry Hair: it is usually dry, dull, and unattractive, Causes could include insufficient production of oil, illness, poor food etc, from the oil gland.
  2. Greasy or oily Hair: caused by over active oil gland, which produces more than is needed.
  3. Soft Hair: usually very light and silky when touched and can be blown by wind.
  4. Tough/Coarse Hair: usually very thick and difficult to comb or manage.
  5. Short Hair: this is hair, which is cut and kept short. It is easier to care for than long hair.
  6. Long Hair: it can result from heredity, good food, care etc. 

Hair type can also be artificial if it has been changed using hair chemicals, or when another thing is attached to the hair .For example wig and attachment.

Functions of the hair

  • It protects the head.
  • It keeps the head warm in cold weather.
  1. It improves personal appearance and adds beauty to a person.

Care and grooming of the Hair

Whatever the type of hair, it is necessary to keep the hair clean and tidy. The following should be done to achieve beautiful hair. 

  1. Brush or comb your hair daily. It stimulates the flow of blood and helps to remove dandruff.
  2. Hair should be washed frequently with shampoo at least once a week and preferably during the day.
  3. Long hairs should be well drained after washing before tying it up.
  4. Hair should be oiled regularly to stimulate the scalp except for persons with greasy or oily hair.
  5. Plait, style or pack your hair neatly.

 

Simple and complex hair care equipment and materials include: combs, brushes, mirrors, plaiting threads, towels, hair dryer, hair sprays, pins, clips etc

 

 

Activities

 Students should divide the hair equipment into simple and complicated. 

Identify 3 people in your class and the type of the hair they have.

 

 

SUB-TOPIC II: Structure, functions, care and grooming of the eye.

This week as a continuation on the study of the human body, we shall discuss on the structure, function and care of the eyes:

                                                     The Structure of the Eyes

The eye is made up of different parts. Each part performs different roles in helping us to see. The parts of the eyes are: Iris, Cornea, Lens, Retina, Optic nerve, Pupil, Tear gland, the eye ball, Eyebrow, Eyelashes, Aqueous and Vitreous humors.

                                         

 

 

DIAGRAM OF THE EYES

 

PARTS OF THE EYES                                 FUNCTIONS                                  

The Iris This is the coloured part of the eye. It surrounds the pupils and helps it to regulate the pupils to darken or brighten.
Cornea The cornea is a protective layer. It helps to keep dirt and dust away from the pupils.
Lens This is the glass-like part of the eyes. It helps the eyes to see things that are so far or nearby changing their size.
Pupils This is the hole in front of the eyeball through which light enters the eyes.
Optic nerve This part of the eye is a sensory nerve, which links the eyeball to the brain.
Retina This is a sensitive spot in the eye where images are formed.
Tear gland This gland helps to pour out tear over the front of the eye. The tears poured out, helps to wash away dusts, which enters the eyes.
Eyes lashes These are the hair at the lid. They help to protect the eye from dirt and dust.
The eye balls These are the organs of sight connected to the brain through the optic nerve.
Eye lid This is the skin covering the eyeball. It can be closed to prevent foreign objects from entering the eyes. 

 

Generally, the eye helps us to see.

 

Care and grooming of the eye.

 

To care for the eyes we should;

 

  1. Use good light when reading or sewing to avoid straining the eyes.
  2. Eat foods rich in Vitamin A, such as green vegetables, palm oil etc.
  3. Avoid looking directly at very bright light e.g. light from electricity, welders, sunlight etc.
  4. Avoid washing our eyes with disinfectants except at the prescription of an optician/ophthalmologist.
  5. Avoid reading small prints for long period; doing this strains the eyes.
  6. Avoid rubbing the eye when there is something in it. It is better to remove the object dipping the eye in a clean bowl of water with frequent blinking.
  7. Relax the eyes by looking up from time to time when watching TV, reading books, writing or sewing.
  8. Avoid holding a book or work too near to the face as doing that may strain the eyes.
  9. Wear glasses if you are so directed by the optician and make sure your glasses are always kept clean.
  10. See an optician in case you have sore watering eyes when reading    

 

Lack of care for the eye could lead to:

  1. Poor eye sight.
  2. Wearing of glasses.
  3. Blindness. 
  4. Eye infection.
  5. Short sightedness / myopia (inability to see objects that are far away).
  6. Long  sightedness / hypermetropia (inability to see objects that are near).

 Conjunctivitis (a contagious disease that causes a lot of itching in the eye).

 

 

Presentation

 

The topic is presented step by step

 

Step 1:

The class teacher revises the previous topics

 

Step 2.

He introduces the new topic

 

Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise

 

 

Conclusion

The class teacher wraps up or concludes the lesson by giving out a short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where the needs arise.
