IDENTIFICATION OF COMMUNITY RESOURCES FOR BETTER SCIENCE TEACHING AND LEANING

Human resources
Human resources are the set of individuals who make up the workforce of an organization, business sector, or economy. "HumanCapital” is sometimes used synonymously with human resources, although human capital typically refers to a more narrow view (i.e., the knowledge the individuals embody and can contribute to an organization). Likewise, other terms sometimes used include "manpower", "talent", "labour", or simply "people".
The professional discipline and business function that oversees an organization's human resources is called human resource management (HRM, or simply HR).
From the corporate objective, employees have been traditionally viewed as assets to the enterprise, whose value is enhanced by further learning and development, referred to as human resource development. Organizations will engage in a broad range of human resource management practices to capitalize on those assets.
In governing human resources, three major trends are typically considered:
1.      Demographics: the characteristics of a population/workforce, for example, age, gender or social class. This type of trend may have an effect in relation to pension offerings, insurance packages etc.
2.      Diversity: the variation within the population/workplace. Changes in society now mean that a larger proportion of organizations are made up of "baby-boomers" or older employees in comparison to thirty years ago. Advocates of "workplace diversity" advocate an employee base that is a mirror reflection of the make-up of society insofar as race, gender, sexual orientation etc.
3.      Skills and qualifications: as industries move from manual to more managerial professions so does the need for more highly skilled graduates. If the market is "tight" (i.e. not enough staff for the jobs), employers must compete for employees by offering financial rewards, community investment, etc
RESOURCE PERSONS
                                           
  Dr. Sarvepalli Radhakrishnan,

( the first Vice President and the second President of the country, was first and foremost a teacher)
                                       A resource person is one who has knowledge, relevant skills, competencies. Teachers are inevitable part of our lives. They play a significant role in the formative years of our development, in one way or the other. When we are young, our teachers play the role of 'second parent', taking care of us and showing us the right path to success. When we grow older, they help us achieve our targeted goals and guide us in such a way that life's toughest challenges seem easier to accomplish. They prove to be the moral guide for us. They recognize the talents of their students, sharpen it, and give it the proper shape, which can prove productive.
                                                       Teacher's Day is dedicated to all those teachers, who have brought about untamed talents of their students and helped them in their overall development. A person becomes famous when he/she is exceptionally good in a particular field. Some teachers have also become well known in the world, for their unmatched achievements and dedication to the sacred profession of teaching. They have been the role models for those, who wish to take up teaching as their profession. The famous teachers committed themselves totally towards the development of their students. Go through our related section and learn all about the life of some of the famous teachers in the world.

EMINENT TEACHERS

Albert Einstein
Some of the famous teachers of the world have set them as a role model by living the life of a whiz kid and making unparalleled contributions to the prosperity of humankind. Albert Einstein is one such great personality, who is remembered for his works in the field of physical science.

Aristotle
Aristotle was a Greek Philosopher. A disciple of Plato, Aristotle is famous for his writings on a plethora of subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, politics, government, ethics, biology and zoology. He held the distinction of being the creator of Western philosophy, in collaboration with Plato and Socrates.

Ayn Rand
Ayn Rand was a Russian-American novelist and philosopher. Ayn Rand's more famous novels include the following 'Atlas Shrugged', 'The Fountainhead', 'Anthem', 'We The Living'. Ayn Rand died on March 6, 1982, leaving behind the legacy of her brilliant work. She shot to fame with her best-selling novels and by developing a philosophical system called 'Objectivism'.

Confucius
Famous throughout the world as a Chinese thinker and social philosopher, Confucius laid great emphasis on personal and governmental morality. He believed in the rightness of social relationships, fairness and honesty. With time, his way of thought came to be developed into a system of philosophy, known as Confucianism, which had a deep influence on Chinese, Korean, Japanese, Taiwanese and Vietnamese thought and life.


Galileo Galilee
An Italian physicist, mathematician, astronomer, and philosopher, Galileo Galilee is best known for his major role in the Scientific Revolution. An ardent supporter of Copernicanism, he brought about great improvements in the telescope as well as the consequent astronomical observations.

Sir Isaac Newton
One of the most renowned physicists of all times, Sir Isaac Newton is also credited as a great mathematician, astronomer, natural philosopher, alchemist, and theologian. Through his Philosophiae Naturalis Principia Mathematica, he laid down the groundwork for most of classical mechanics.

Pythagoras
Pythagoras is regarded as one of the greatest mathematicians that the world has seen till date. He is also credited with being a great mystic and scientist. He founded the religious movement called Pythagoreanism and also gave the world Pythagorean Theorem, which is used in mathematics till date.

Friedrich Froebel
Creator of the kindergarten system, 'Friedrich Froebel', is a famous German educationalist, who implemented revolutionary ideas to improve the educational system. He had a shattered and unhappy childhood, being neglected by his father and step-mother. He re-defined the concept of education and emphasized

Natural Resources
Natural resources occur naturally within environments that exist relatively undisturbed by humanity, in a natural form. A natural resource is often characterized by amounts of biodiversity and geodiversity existent in various ecosystems.
Natural resources are derived from the environment. Some of them are essential for our survival while most are used for satisfying our wants. Natural resources may be further classified in different ways.
Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, and air, as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores, oil, and most forms of energy.
There is much debate worldwide over natural resource allocations, this is partly due to increasing scarcity (depletion of resources) but also because the exportation of natural resources is the basis for many economies
Some natural resources such as sunlight and air can be found everywhere, and are known as ubiquitous resources. However, most resources only occur in small sporadic areas, and are referred to as localized resources. There are very few resources that are considered inexhaustible (will not run out in foreseeable future) – these are solar radiation, geothermal energy, and air (though access to clean air may not be). The vast majority of resources are exhaustible, which means they have a finite quantity, and can be depleted if managed improperly.
Examples of Natural Resources
A sacred grove or sacred woods are any grove of trees of special religious importance to a particular culture. Sacred groves were most prominent in the Ancient Near East and prehistoric Europe] but feature in various cultures throughout the world. A sacred grove or sacred woods are any grove of trees of special religious importance to a particular culture. Sacred groves were most prominent in the Ancient Near East and prehistoric Europe, but feature in various cultures throughout the world. Ancient holy trees still exist in the English countryside and are mentioned often in folklore and fairytales.
A lake is a body of relatively still liquid (prototypically water) of considerable size, localized in a basin, that is surrounded by land apart from a river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds.[1][2] Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.
Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.
Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic or recreational purposes.
A river is a natural watercourse, usually freshwater, flowing towards an ocean, a lake, a sea, or another river. In a few cases, a river simply flows into the ground or dries up completely at the end of its course, and does not reach another body of water. Small rivers may be called by several other names, including stream, creek, brook, rivulet, and rill. There are no official definitions for generic terms, such as river, as applied to geographic features, although in some countries or communities a stream may be defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague.
Rivers are part of the hydrological cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, and the release of stored water in natural ice and snowpacks (e.g. from glaciers). Potamology is the scientific study of rivers while limnology is the study of inland waters in general
The sea, the world ocean, or simply the ocean, is the connected body of salty water that covers over 70 percent of the Earth's surface. It moderates the Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been travelled and explored since ancient times, the scientific study of the sea—oceanography—dates broadly from the voyages of Captain James Cook who explored the Pacific Ocean between 1768 and 1779. In geography, "sea" is used in the names of smaller, partly landlocked sections of the ocean, for example the Irish Sea, while "ocean" is used in the names of the five largest sections, such as the Pacific Ocean.
The most abundant ions in sea water are chloride and sodium. The water also contains magnesium, sulfate, calcium, potassium, and many other components, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however the relative proportions of dissolved salts vary little across the oceans. Carbon dioxide from the air is currently being absorbed by the sea in increasing amounts, lowering seawater pH in a process known as ocean acidification, which is likely to damage marine ecosystems in the near future.
Winds blowing over the surface of the sea produce waves, which break when they reach shallow water. Winds also create surface currents through friction, setting up slow but stable circulations of water throughout the oceans. The directions of the circulation are governed by factors including the shapes of the continents and the rotation of the earth (the Coriolis effect). Deep-sea currents, known as the global conveyor belt, carry cold water from near the poles to every ocean. Tides, the generally twice-daily rise and fall of sea levels, are caused by the rotation of the Earth and the gravitational effects of the orbiting Moon and, to a lesser extent, the Sun. Tides may have a very high range in bays or estuaries. Destructive tsunamis can be caused by submarine earthquakes arising from tectonic plate movements under the oceans, volcano eruptions, huge landslides, or the impact of large meteorites.
A wide variety of life, including viruses, bacteria, protists, algae, plants, fungi and animals, lives in the sea, which offers a wide range of marine habitats and ecosystems, ranging from sunlit surface waters to the enormous depths and pressures of the cold, dark abyssal zone. The sea also varies in latitude from the cold waters beneath the Arctic ice to the colourful diversity of coral reefs in the tropics. Many of the major groups of organisms evolved in the sea and life may have started there.
The sea provides people with substantial supplies of food, mainly fish, but also shellfish, mammals and seaweed, whether harvested in the wild or farmed underwater. Overexploitation of these food resources has become a major problem. The sea also serves other purposes, including trade, travel, mineral extraction, power generation, warfare, and leisure activities such as swimming, surfing, sailing and scuba diving. The sea also suffers from marine pollution. The sea has played an important part in culture throughout history.
