What is basic science as a subject?
The word “basic” refers to something that is necessary and most important to all people. Basic science as an integrated science course is a subject that deals with the study of living things and non-living things. It also combines all other science subjects such as physics, biology, health science, agricultural science, geography, etc.

Menstruation

Ovulation
Fertilization
WHAT IS MENSTRUATION?
Menstruation is the monthly flow of blood from the womb, through the vagina in every woman of childbearing age. This period is called Menstrual Period. It takes place after about every 25-30 days. The number of days before the next period is called ‘Menstrual Cycle’. The menstrual period is different from one person to another.
I. MENSTRUAL HYGIENE
As the body sends out blood, it also sends out body odour. It should be noted that during the menstrual period, there is a high risk of infection. To learn more: Click here

Symptoms of Pregnancy
Growth of the foetus
A. WHAT IS PREGNANCY?
Pregnancy is the result of the fertilization of the female ovum or egg by the male cell or sperm. Pregnancy is also the period from conception to birth. After the egg is fertilized bya sperm and then implanted in the lining of the uterus, it develops into the placenta and embryo, and later into a foetus. Pregnancy usually lasts 40 weeks, beginning from the first day of the woman’s last menstrual period, and is divided into three trimesters, each lasting three months. Pregnancy is that state or condition when a female carries a foetus in her womb for about nine months. To learn more: Click here
Week Three: Topic: Forces
Introduction
In everyday language, force suggests the use of compulsion or strength. If your parents forced you to wash your school dress after school on a Wednesday.. it means that they compelled you to do it.
Concept of Force
A force is a thing that,
1. changes the shape of a body
2. makes a body at rest move
3. changes the speed of a moving body
4. causes a moving body to change direction
5. causes a moving body to stop

Week Four: Topic: Calculation Of Gravitational Force
Introduction
Gravitational
This is a force with which the earth attracts objects towards its centre. If you throw a coin up, what do you expect? You will notice that the coin will go up and at a certain point stop before beginning to come down. Is there anything pulling the coin down? Yes, although you may not see anything pulling it. The force due to gravity is pulling the coin to the centre of the earth.
Assuming you are holding a mass of 20g in your hand. Climb a tree or a high object. Release the mass, what do you notice? You will notice that the weight did not go horizontally but vertically.

Week Five: Topic: Space Travel
Introduction
The age we live in is sometimes called the Space Age. It is in this age that the longing of man to reach out beyond the earth changed from wish to reality.
The Universe
The Universe is a very expansive space which includes all the stars and our solar system. Our solar system consists of the sun and nine planets which include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto and their moons. The light, which reaches the earth comes from the sun and the stars. The stars are themselves suns with their own solar systems. Light travels at a very high speed. The sky on a bright night seems to be filled with stars. though each of the stars when observed appears very small, the stars are far bigger than the earth on which we live. Some of the larger stars have been estimated to be many million times the size of the earth. The stars are not scattered regularly in space. To learn more: Click here
Week Six: Topic: Gravitational Weightlessness
Introduction
Gravitation is a scientific concept that lead had been known and understood from Newton’s time. It was he who propounded the laws of universal gravitation from mathematical theory. Since that time, the theory has been used by other scientists in computing various constants and quantities that relate to objects on earth and in space. Gravitational pull is a force of attraction that everybody exerts on every other body. The earth has a large gravitational pull on objects because of its large size.
Meaning of Gravitation
There is a force which pulls things thrown upward towards the earth. This force is called gravitation. To learn more: Click here
Week Seven: Topic: Earth In Space
Introduction
The interest of man in space has existed since ancient times when man employed the naked eyes to study and speculate on the moon, the stars, the sun, and other things which were imagined to be there in space. As time went by, man began to carry out more systematic studies of space. By the second century AD, a Greek mathematician called Ptolemy proposed that the earth moved in space. By the 16th century AD, some other scientists such as Tycho Brahe and Kepler had deducted the relationships between the motion of the earth around the sun and the motion of the moon around the earth. In the year 1686, Isaac Newton deduced and published the laws of mechanics. These included those governing the circular motion of the earth around the sun.

Week Eight: Topic: Satellite
Meaning of Satellite
A satellite is an object that revolves around another object (which is known as its primary). Satellites can be man-made or may be naturally occurring such as moons, comets, asteroids, planets, stars and even galaxies.
An orbit is a path that an object takes around another object while under the influence of a source of centripetal force, such as gravity.
Orbits were first analyzed mathematically by Johannes Kepler who formulated his results in his three laws of planetary motion. Isaac Newton demonstrated that Kepler’s laws were derivable from his theory of gravitation and that, in general, the orbits of bodies responding to the force of gravity were conic sections.

Week Nine: Topic: Consequences of Teenage Pregnancy
Introduction
Teenage pregnancy is a pregnancy that happens in human females under the age of 20 at the time that the pregnancy ends. A pregnancy can take place in a pubertal female before marriage, which signals the possibility of fertility, but usually occurs after marriage.
Teenage pregnancy is defined as a pregnancy that occurs in women below the age of 20. It is common that at this age, the girl has not completed her education and is completely dependent upon her parents thus unable to provide for the unborn child. To learn more: Click here
