They come up with unique models at district-level contest held to select NCSC projects
District-level competitions held to select projects to be submitted at the 18th National Children's Science Congress-2010 have thrown up several interesting models on the focal theme ‘Land resources – use for prosperity–save for posterity'.
A project developed by Sai Lakshmi Mounika, a student of Class 9 of Bhashyam Public School, highlighted the importance of using biofertilizers to enhance soil fertility. The student, under the guidance of senior science teacher and lab in-charge B. Venkat Rao, studied the soil fertility at the Lam Farm and came to a conclusion that dwindling presence of earthworms in agricultural fields was one of the primary causes behind soil infertility.
Indiscriminate use of complex fertilizers to enhance productivity of commercial crops like cotton and chilli affected the diversity of microorganisms, Mounika pointed out.
A group of students presented a bread mould model and explained the diversity of microorganisms in natural ecosystem. Yet another student Mary Simran Malhotra, a student of Class 9 of Bhashyam Blooms, showcased the management of soil fertility. In all, 45 scientific models were presented at the competitions.
Besides corporate schools, students of municipal and ZP High Schools also came up with innovative models. The projects could be developed in the sub themes of ‘Know your land', ‘Functions of land', ‘Land quality', ‘Sustainable use of land resources' and ‘Community knowledge on land use'.
The models were evaluated by four senior scientists of the Lam Farm – K. Veeraiah, M. Adi Narayana, A. Lalitha Kumari and D.V.S Maruthi Kishore. The projects were graded as per parameters prescribed for the NCSC projects.
