- 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.
