Sub-topic 1

Water borne diseases

Diseases caused by unclean (dirty) water are called water borne diseases. The following are some of the water borne diseases.[mediator_tech]

1. CHOLERA: It is caused by harmful bacteria that inflame the intestine and cause extreme diarrhea. Cholera is the most common diseases that can be contacted by drinking unclean water.

The symptom of cholera is frequent stooling with vomiting which lead to dehydration. Cholera can be prevented by boiling water before drinking.

2. DYSENTRY: It can be caused by a one-celled animal called

Amoeba or by certain bacteria.

3. DIARRHOEA: the symptom of diarrhea is frequent stooling which leads to dehydration, abdominal pains, bloating of the belly, feverish conditions and cramps. To prevent diarrhea, the food we eat and our drinking water should be hygienic.

4. TYPHOID: It is caused by bacteria called salmolena typhi. Symptoms of typhoid fever manifest within three weeks of infection.

Symptoms include feeling cold, serious headache, running stomach,

Constipation, enlarged liver and spleen and high fever. Typhoid fever could be prevented by boiling water before drinking, hygienic handling of food and being immunized against the diseases.

Sources of clean water.

1 Pipe-borne water

2 Spring water.

3 Rain water

4 Deep well water

Evaluation

Mention three borne diseases.

List the sources of clean water.

Sub-topic: 2: Water treatment processes

FILTERATION: – This is the process of removing impurities i.e. mud, soil, leaves from water. Filter paper is used in the laboratory while filter beds are used at water co-operations.

CHLORINATION: – Chlorine gas is added to water to kill bacteria. It is harmless to human beings. It is also used to purify the water in swimming pools.

DISTILLATION: – This is a process of obtaining pure water from impure water by using an apparatus called Lie Bib Condenser.

DESALINATION: – This is the process of taking away salt from sea water.

FLOCCULATION: This is the dissolution and stirring of alum in water to make tiny solid particles suspended in water to stick together (flocculate).

Advantages of using pipe-borne water

1. It is clean and colourless.
2. It is odourless.
3. it is tasteless.

IMMUNIZATION

Immunization is a method of stimulating resistance against specific diseasesin the human body using microorganisms (bacteria or viruses) that have been modified or killed. It is also called vaccination or inoculation. The system in the body that keeps disease-causing organisms from entering our body is called Immune system. Immunization of the child begins during pregnancy. The deadly diseases that require immunization are Polio, chickenpox, Pneumonia, measles, whooping cough, hepatitis, malaria, tuberculosis, cholera, tetanus diphtheria etc.

Sub-Topic 1: Definition of STI’s HIV\AIDS.STI’S means sexually transmitted infections. These are diseases that can be contracted through sexual activities. Examples include gonorrhea, syphilis, herpes, Chlamydia, Candida infections and HIV and AIDS.

HIV-AIDS

Aids is a very dangerous disease. The full meaning of AIDS is Acquired Immune Deficiency Syndrome. An aid is caused by a virus called Human Immune deficiency Virus (HIV). HIV-AIDS has no cure yet. Human body has an Immune defense system which protects our bodies against attacks from diseases. The virus (HIV) damages this Immune defense system.

When the virus is in the body; it is said to be HIV positive and that is what develops to HIV-AIDS. When this happens, the person’s body will not be able to fight any other diseases (such as fever, cough, tuberculosis, pneumonia etc) that attack person. The person will die after some time. HIV-AIDS can affect anybody no matter the age.

Safe age for reproduction:

The safe age for reproduction is when somebody is fully matured and ready to take responsibilities. You have to answer the following questions:

State of Matter:

Matter can be classified into the following group:

1. Living and non-living things
2. Using state of matter
3. Using physical criteria like size, weight, texture, shape, color, smell, taste.

There are three states of matter which are solid, liquid and gas.

SOLID:

The particles of solid are arranged in an orderly manner. A strong intermolecular force holds the particles together. The particles are very much close together. Solids have definite shapes, volume and fixed mass. Examples of solid are salt, sugar, ice-block; stone e.t.c. solid undergoes translational motion and oscillatory motion.

LIQUID:

The particles of a liquid are not very close together. Liquid particles are a bit free to move about because of the moderate intermolecular force between particles. Liquid does not have a definite shape but takes the shape of the container. Liquid are fluid which flows or diffuse in all directions. Examples are water, blood, ink, urine. Liquid have definite volume, fixed mass. Liquid cannot be compressed or squeezed into a smaller space. Liquids undergo three kinds of motion, vibration, rotational and translational.

GAS:

The particles of gas are very far apart because of the very weak intermolecular force holding the particles. They move about freely at great speed. Gases have no definite shape, volume but have fixed mass. Gases can be compressed. Examples of gases are air, ammonia, steam, oxygen e.t.c.

Change of state

When solid water [ice] is heated, its particles move faster and break away from the ordered arrangement. The solid melts to become a liquid. The melting point of a substance is the temperature at which solid changes to liquid. The boiling point of a substance is the temperature at which liquid changes to gas.

Change of state in water

[iv] To seek reproductive mates or sites

Types of movement in plants are phototropism; movement towards light. Geotropism is the movement towards gravity.

Mode of feeding:

1. Authotrophic mode of feeding: This is found in green plants .Light energy is trapped by green plants and combined with inorganic materials (CO₂) to produce food.eg photosynthesis.

2. Heterotrophic mode of feeding: This is found mainly in animals .They are unable to produce their own food hence depends on already manufactured solid food which must be digested and absorbed. Under this mode of feeding, organisms (animals) can be classified according to their feeding habits.

A] Herbivorous: These are the animals that feed mainly on plants. These are called ruminants. Examples are goats sheep and cattle.
