CONTENT

HUMAN REPRODUCTIVE SYSTEM

As human and living things we give birth to young ones. That is reproduction. There are organs in male and female that aid reproduction processes.

MALE REPRODUCTIVE SYSTEM

The male reproductive system consist of a penis. Vas deferens (Sperm duct), a pair of testes in a scrotal sac, urethra and some associated glands.

FUNCTIONS OF THE MALE REPRODUCTIVE SYSTEM

1. Testes – produces sperm.
2. Urethra – carries sperm within the penis into the female organs.
3. Scrotal sac – protect testes.
4. Penis – introduces sperm into the vagina.
5. Vas deferens – transfer sperm from testes to seminal vesicle.

FEMALE REPRODUCTIVE SYSTEM

The female reproductive System

The female reproductive system consist of the Ovaries, Oviducts, Uterus and vagina.

FUNCTIONS OF THE FEMALE REPRODUCTIVE SYSTEM

1. Ovaries – produces eggs.
2. Oviduct – carries egg cells to the uterus.
3. Uterus – receives and cares for developing foetus.
4. Vagina – Outlet from the uterus or womb.

REPRODUCTION PROCESS

1. The male and the female comes together and have sex.
2. The male sex produces the male sperm (gametes) while the female sex produces the female egg cell (gametes or Ovum).
3. The sperm is introduced into the female sex organ where it fuses with the egg during fertilization.
4. The fusion produces a zygote, which develops into a new offspring inside the uterus of the female.
5. The zygote then develop to embryo.
6. After nine months the female will give birth to a baby.

ENTRY BEHAVIOUR/ PREVIOUS KNOWLEDGE: the students are familiar with water projects.

CONTENT

Air is a mixture of gases (especially oxygen) required for breathing. It is a colourless, odourless and tasteless mixture of gases. Air expands when heated.

 PROPERTIES OF AIR

1.  it has weight
2.  it occupies space and
3.  It is present everywhere.

PART OF AIR

AIR part consist of

1. Active air or Oxygen: Active air allows substance to burn. It is one fifth (20%) the volume of air.
2. Inactive air. It is about four fifth (80%) of air. It is more of Nitrogen.

PRESSURE

Pressure is the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit).

WHY THINGS MOVE IN AIR (AIR AND PROPULSION)

Things moves around because of the pressure of the air. Like kite is a light object with large surface.so it is very easy to float with the pressure of air. Likewise also any light object with a large surface area can float easily with air pressure.

 USES OF AIR PRESSURE

1. It enable aero plane to fly easily on air.
2. It helps in the propulsion of rocket.
3. It help human when using parachute to land safely from air.
4. It helps some birds to stay in the air.
5. It helps birds when flying.
6. Wind mill (Turbine generator) used the wind by air pressure to generate electricity.

Air aid burning because air contain energy when you blow air over match stick, and its flame is put out, it means the active air around it is not enough. The inactive air, which forms the greater part of air. it is the part that helped put out the flame.

CONTENT

Mineral resources are valuable substances which have been deposited naturally underneath the earth.  They are removed from the earth by drilling and mining.

Almost all states in Nigeria have its own raw mineral resources.

TYPES OF MINERAL RESOURCES

1. Organic minerals: these are formed from living things.
2. Inorganic Minerals: these are formed from non – living organisms.

FORMS OF MINERALS

When minerals are gotten they are their raw form, then they now refined through mining or drilling.

1. Solid Minerals: they are extracted from the earth through mining. They can be identified using colour, lustre, weight and shape. Like tin are gotten through mining. When solid minerals are in their raw form, they are referred to as ‘Ore.’
2. Liquid minerals or gas: liquid minerals are exploited through drilling process from the earth and are separated into different product using fractional Distillation. Like crude oil can be separated into petrol, kerosene, diesel, etc.
