3. INTODUCTION
Analysis as a term stands for the process of breaking or separating a thing
into its smaller parts, elements or constituents.
We can break the contents of the prescribed unit in a subject into sub-
unit, concepts ,sub concepts etc. by carrying out a process called content
analysis
DEFINITION OF CONCEPTS
Concepts may be thought of an frame work of an event or object.
Concept is a process of representing a common property of an object or
events.
Concepts can be defined as a class of stumuli which have common
characteristics....Dacacco.
EX:-Heat is transformed from higher to lower region.
Intensity of light decreases with distance.
4. CHARACTERISTICS OF CONCEPTS
It i an individual mental image of thing formed by generalization of
particular events.
It is formed by the number of related experience of the event.
It is an idea of logical species.
The concept of integrated by nature.
The concept has potential to live long.
IMPLICATIONS OF CONCEPTS
It develops knowledge,
It improves and develops individual experiences.
It guides the learner in right path.
It helps to develop mathematical, scientific ideas and vocabulary.
It favour established laws.
5. TYPES OF CONCEPTS
Three types of concepts
1.CONJUNCTIVE CONCEPTS:-Conjuctive concepts have more than one
dimension often obstract and all of them present to define that concept.
2.DISJUNCTIVE CONCEPTS:-Disjunctive concepts also involve many
dimensions but any of them by itself constituents an instance of the
concept.
3.RATIONAL CONCEPTS:-Involves a dimension which tells us a relationship
between any two facts.
8 TH CLASS CONCEPTS
FORCE AND PRESSURE
Force could be a push or pull.
A force arises due to the interaction between two objects.
Force has magnitude as well as direction.
Force per unit area is called pressure.
Liquids and gases exert pressure on the walls of their containers.
The pressure exerted by air around us is known as atmospheric pressure.
6. FRICTION
Friction opposes the relative motion between two surfaces in
contact. It acts on both the surfaces.
Friction depends on the nature of surfaces in contact.
Friction depends on how hard the two surfaces press together.
Static friction comes into play when an object is sliding over another.
Sliding friction is smaller than static friction.
The sole of the shoes and the tyres of the vehicle are treated to
increase friction.
Fluid friction can be minimized by giving suitable shapes to bodies
moving in fluids.
SOUND
Sound is produced bz vibrating objects.
In human beings , the vibration of the vocal cords produced sound.
Sound travels through a medium (gas, liquid or solid ). It cannot
travel in vaccum.
7. • The eardrum senses the vibrations of sound. It sends the
signals to the brain. This process is called hearing.
The number of oscillations or vibrations per second is called the
frequency of oscillation.
The frequency is expressed in hertz (HZ).
Larger the amplitude of vibration. The higher is the pitch and
shriller is the sound.
Unpleasant sounds are called noise.
LIGHT
Light is reflected from all surfaces.
Regular reflection takes place when light is incident on
smooth,polished and regular surfaces
Diffused or irregular reflection takes place from rough surfaces.
Image formed in a plane mirror undergoes lateral inversion.
Spliting of light into its constituent colours is known as dispersion.
8. Stars and the the solar system
• The phases of the moon because we can see only that part of the moon
which reflects the light of the sun towards us.
• Stars are celestal bodies that emit light of their own. Our sum also a star.
• Stars appear to move from east to west.
• The solar system consists of eight planets and a host of asteroids, comets
and meteors.
• The artificial satellites revolve around the earth. They are much closer
than the moon.
Pollution of air and water
• Air pollution is the contamination of air by impurities which may have a
harmful impact on the living organisms and the non-living components.
• Pollutants are the substances which contaminate air and water.
• Carbon monoxide,nitrogen oxides,carbon dioxide,methane and sulpher
dioxide are the major pollutants of air
• Increasing levels of greenhouse gases like co2 are leading to global
warming.
9. Motion
Motion is a change of position: it can be decribed in terms of the
distance moved on the displacement.
The motion of the object could be uniform or non uniform depending
on wether its velocity is constant or changing.
The speed of the object is the distance covered per unit time and
velocity is the displacement per unit time.
The acceleration of an object is the change in velocity per unit time.
Uniform and non uniform motions of objects can be shown through
graphs.
If an object moves in a circlular path with uniform speed,its motion is
called uniform circular motion.
10. Conclusion
In relation to the debate about the legitimacy of content analysis, in
the above examples data has been collected from respodents in
their own environment and language: and numerical anaysis
techniques have offered a systematic camparison of data leading to
an improved understanding it. This does not of itself invalidate
content analysis as a methodology to describe phenomena and
understanding transactions occuring in the data.
