Students from different schools here on Friday came out with excellent working models to demonstrate applications of science to everyday life situation.

A group of students came out with a solution to streetlights remaining switched on even during daytime, wasting electricity generated from conventional non-renewable sources of energy at a time when there is severe power shortage.

They exhibited renewable solar power-based streetlighting system which automatically switches on and off as and when required.

Another group of students demonstrated how electricity could be generated from bio-wastes, while yet another group used the bicycle dynamo to recharge mobile phones. The members of the GenNext explained the importance to check the severe biodiversity loss and stop degradation of the forests.

“Our effort is to develop scientific temper among students for them to mature into good scientists in the future,” said the Andhra Pradesh Tutorials and Convents Association (APTCA) State Organising Secretary Prakash Babu. Scientific experiments help students learn quickly than passive classroom teaching, added senior educationist P.H.G.Krishnam Raju.

Students from 32 schools participated in the science fair held at the P.V.R. Municipal Boys High School Grounds here by the APTCA, added APTCA president P Jali Reddy and convenor Eshwara Prasad.
