Need and Significant of physical science
- 1. PEDAGOGY OF PHYSICAL SCIENCE 1. NEED AND SIGNIFICANCE & VALUES OF TEACHING PHYSICAL SCIENCE
- 3. INTRODUCTION
- 4. • Physical Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works with observable physical evidence as the basis of that understanding. It is done through observation of natural phenomena, and or through experimentation that tries to stimulate natural processes under controlled conditions. • Just a few hundred years after Thales, the Greek philosopher Aristotle made a very important contribution to science. Prior to Aristotle, other philosophers believed that they could find the truth about the natural world by inward reflection—in other words, just by thinking about it. Aristotle, in contrast,thought that truth about the natural world could come only from observations of nature and inductive reasoning. He argued that knowledge of nature must be based on evidence and logic. This idea is called empiricism, and it is the Basis of Science Today.
- 5. WHAT IS PHYSICAL SCIENCE? 1. Physical science is a branch of natural science that studies non-living system, in contrast to life science. 2. The Main purpose of teaching Physical science in secondary to grasp systematically the basic knowledge of knowledge of physical science needed for the further study further study of modern science and technology
- 6. BRANCHES OF PHYSICAL SCIENCE
- 7. SCOPE OF PHYSICAL SCIENCE • Anything that is outside the boundaries of senses of human being is outside the limits of science.In other words, the scope of physical science includes everything within the realm of the sense of human beings. • Physical Science deals with the natural word, thr realm of nature, matter and energy. • Physical Science is not limited to only what is observable.
- 8. AIMS OF TEACHING PHYSICAL SCIENCE 1. To know about the facts and Principles of science and its applications, consistent with the stage of cognitive development. 2. To develop a historical and developmental prospective of science. 3. To nurture the natural curiosity, aesthetic sense and creativity in science and technology. 4. To cultivate scientific temper, Objectivity and critical thinking.
- 9. NEED AND SIGNIFICANCE OF TEACHING PHYSICAL SCIENCE • Science is one of the human activities that man has created to gratify c ertain human needs and desires. The search of truth became the dominant motive in the prosecution of science . The teachingof science imparts training in the scientific method and develo ps scientific attitude which are very valuable and at the same time are transferable to other situations in lif e. • Therapid advancement of science and technology and increasing need for scientist and technologies have made it all the moreimportant to provide for science based education in the schools Science has now become acompulsory subject in the school curriculu
- 10. PHYSICS AS A SCIENCE • Physics, in every day terms, is the science of matter and its motion; the science that deals with concepta such as Force, energy mass, and Charge For Example. More accurately, it is the general analysis of nature, conducted in order to understand how the world around us behaves. • In One form or another, physics is one of the oldest academic disciplines, and possibly the oldest through
- 13. • Sometimes synonymous with philosophy,chemistry and even certa in branches of mathematics and biology during the last two millen nia, physics emerged as a modern science in the 16th century a nd is now generally distinct from these other disciplines;although the boundaries between physics and all these other subjects still remain difficult to define. • Today , Physics is a broad and highly developed subject that is for practical reasons split into several general subfields. In addition to this, it can also be divided into two conceptually different branches: Theoretical and experimental physics; the former dealing with the development of new theories and the latter dealing with the experimental testing of these new, or existing, theories.

When the ball on one end is pulled back and then let go, it swings into the other balls. The ball on the opposite end then swings up with an equal force to the first ball.
- 15. CHEMISTRY AS A SCIENCE • Chemistry is the science concerned with the composition, structure, and Properties of Matter, As well as the changes it undergoes during chemical reaction. • Disciplines within chemistry are traditional groupedby the types of matter being studied or the kind of study.
- 16. Disciplines in Chemistry MEANINGS Inorganic Chemistry Study of Inorganic Matter Organic Chemistry Study of organic matter Biochemistry Study of Substances found in biological organisms Physical Chemistry Energy related studies of Chemical Systems at Macro, Molecular and Sub Molecular Scales Analytical Chemistry Analysis of Material Samples to gain an understanding of their composition and
- 17. • Chemistry is the Scientific study of interaction of Chemical Substances that are Constituded of atoms or the Subatomic Particles : Protons, Electrons, Neutrons. • Atoms combine to produce molecules or crystals. Chemistry is often Called “Central Science” because in connects the other natural Science, Such as astronomy, Physics, matterial Science, Biology And Geology.
- 19. UTILITARIAN VALUE • We are living in an age of science and technology. Physical Science has entered in our life and daily activities. • All our activities are controlled and fashioned by it. There is a vast storehouse of natural power such as wind, waterfall, heat of the sun, etc. which science shows how it is useful for us. • Science has revealed from nature almost all the hidden treasures. It restores eyes to the blind, hearing to the deaf, legs to the lame, even life to the dead. So it is very essential to have some elementary knowledge of science for becoming a full member in the society.

- 22. Vocational Value • Knowledge of science forms the basis for many vocational studies like medicine, • engineering, agriculture or any other profession. Further the study of science forms the basis for • many hobbies like bee keeping, radio servicing, photography, etc. Moral Value • Science has more moral value. It is the search for truth in a faithful manner. When a • scientific theory has religious and philosophic or any other kind of human interest, it no longer • remains disintegrated passion for the truth. It teaches the pupil to
- 23. Cultural Value • Science has aided the growth of consciousness by making us more aware of the universe we live in. Through the practical application of scientific discovery our civilization is undergoing constant change which in turn brings about situations that threatens the well- being of the future generations. Scientists take an active part in the vital issues of the country so as to bring about consideration and integration of scientific development and our cultural heritage.
- 24. Aesthetic Value • Aesthetic sense is the most important consideration with all scientific men for it meets one of the deepest needs of human nature which manifests itself as the desire for beauty. • To a man of science, practical application is just a by- product of his autonomous activity. • The search for universal laws and comprehensive theories undoubtedly the manifestation of the aesthetic motive is very apparent and the satisfaction they get from it seems to be indistinguishable from those of an artist.
- 25. CONCLUSION There are as many preconceptions and misconceptions about science. Science is not a finished enterprise and many things in science are still need to discover. Science offers solution to the problems. The application of science can offer solution to some of the problems where as it can also
