1) We live in a scientific and technological age and no citizen can function effectively in a developed society without a basic scientific literacy and certain elementary skills. Every citizen needs to live a healthy life with proper sanitation and clean surroundings.
E.g. the knowledge and skills required by modern householder in dealing with electrical, plumbing, and human first-aid may be cited as some justification for teaching science to all children in school.
2) We depend upon scientific knowledge and understanding for economic and material advancement. Science has provided so many aids for ‘the good life’ from bicycle to jet aircraft, antibiotics to heart surgery, radar to colour television, and fertilizers to plant growth hormones.
Although we are beginning to realize many follies in the large-scale application of science and technology in terms of a net environmental damage, the fact is that we will need science and technology in a better way which would not affect the environment adversely) and to enable more people to live on this planet in conditions which do greater justice to the dignity of man.
3) Science, if studied properly, develops power of thinking, reasoning, curiosity, open mindedness, and ultimately develops scientific attitude or scientific temper. Thus science could be aimed as an instrumental for social change towards a better society.
