To Study the effectiveness of instructional material (Science) on environmental awareness of VIII standard students

Abstract

Human beings interact with environment in three ways, as space for living, as a bank of resources such as food, water, materials and energy as a sink for waste disposal. As the most enlightened species, Homo sapiens, human has paramount responsibilities to preserve the environment and improve it qualitatively not only for himself but also for the future generation. However unfortunately with development in science and technology ,man has been dominating nature ,shaping the environment to suit itself using everything around him without scant regard what so ever for the natural scheme of interdependent ecological regimes. In the name of development, man has been ruthlessly consuming natural resources and polluting the environment, without scant regard for its assimilative power and carrying capacity. The environmental crisis the world is facing today is due to overpopulation .hunger poverty ,people unlimited desire, ignorance and materialistic approaches to life in the world over have starlet! realizing that much of what Got! created .man is now destroying, not only earth's basic lire supporting capital or forests, animal species and soils but also its fresh water and oceans and'even the ozone shield which protect our life forms from the sun's more deadly rays. Now we are threating ourselves with climate change - a rapid rise in global temperature and sea levels -greater perhaps -in the next 40-60 years than in the 10,000 years since the last ice age. These environmental threats that now facing us could have so much momentum that unless steps are taken to reverse them, they may soon overwhelm our ability to respond ever threatening all living beings including man himself with disaster or extinction Education for human is a recent development in all parts of the world. The world education means E Economical development D Development of ideas 1 . RIE Library Bhopal U Utilities of local bodies C Care of man and environment A - Awareness of the universe T - Training of teachers I - Imagination of environmental education o - Optimum percepts N Number of small family .The people become aware of the interrelationships of man and his world; the scope of the environment has also widened. Human needs to' understand better their inter relations, with various Components of the environment includes - E - Everybody needs to search for a solution N - Now that the earth is harmed by pollution V - Vegetation and habitats increasingly lost I - In the pursuit of progress without counting the cost R - Recycling not a choice, it is must if not, our planet turned into dust. o - Our fragile ozone layer is always destroyed. N - Now that CFC are widely employed. M - Mankind's habitat could really be fun. E - Energy saving resources could really be done. N - Now are great need is to select and protect, . ' T - To balance and conserve our earth with respect. Knowledge in the school curriculum is comprised of language, mathematics , physical .and natural sciences as well HS social studies apart from several co curricular subjects and activities. The perspective of looking at this classification changed in the last two decades with' the physical, 'natural and social SCIences being treated as a whole and referred to as Environmental science.
