Project Name : Natural Resources and their Conservation

Theme Name : Natural Resource & their Conservation


S.C.I.E.N.C.E. (Some creative innovation energy with Notified common experiments)

Aim: Our main motto is to control energy crisis and water crisis by the use of some uncommon scientific innovations and technology in everyday life. Secondly to promote organic farming, use of water sensors in agriculture to save water and energy. Ultimately, we aim to prevent rail accidents at the railway crossings by the use of light sensors.

Scientific Principle Involved: We have used the basic principle of photoconductivity in light sensors, conduction of electricity by water and also the principle of decomposition of biomass to produce natural gas to generate electrical energy for a better tomorrow.

Materials Used: Light sensors (LDRs), LED bulbs, conducting wires, 9V cells, thermo cols, aluminum pieces, sliding lens, paint, sticks, fevicol, toys, ply and POP.

Working Investigation and Findings: According to our survey, in Jharkhand we have many open cast mines [West Bokaro kolyari ghat, Kujama Village, Jama Dobha, etc.] which are now left vacant after extraction, also these areas have frequent water shortage. For which we have decided to turn those useless mines into water reservoirs. In addition, the state has enormous potential for cultivation of a number of horticultural crops; however, the productivity is low due to nonavailability of quality planting material and irrigation. The cultivation of crops is heavily dependent on rainfall. According to our survey, 20.68% of the land of farmers has access to irrigation. 65.56% farmers use wells, 26.67% use life irrigation, 4.44% use ponds and 3.33% use other sources of irrigation. In the state, the percentage of area under irrigation is 28.3%. With emphasis on achieving self sufficiency in food grains, Jharkhand should give top priority to increase the coverage under assured irrigation and this provides the scope for farm mechanization for increasing productivity via water sensors and use of water reservoirs. In urban sector, energy utilization and waste generation in very large so, balancing this two aspects we have done a survey in our locality manipulating the total waste generation per day. We found that from an average society (of 50 families) we can easily have 100-150 kg of waste daily which is enough to lighten up the whole society for 3-4 days free of cost. In metropolitan cities, our smart tower can harvest 66% of energy required for this entire skyscraper and in small towns like our hometown Hazari bag use of LDR in street lights can save 40-45% of energy which is simply wasted due to our negligence and the installation of our genuine anti rail accident system can save millions of life!!!

Utility and Further Scope of the Model: This model has been carefully designed and evaluated thinking about is present and future uses and how it can be brought to practical uses in the future. Once successfully brought to practical use the idea behind this project will not only prove to be energy efficient but will also contribute towards a greener tomorrow… In context to further scope of this model, we aim at establishing our water sensors in forms with automatic motor on/off facility, light sensors in homes, street lights and in security. Our anti rail accident system in roads and runways, etc. with few modifications.

Name of the School: St. Xavier’s School, Hazaribagh, Jharkhand.
