DK students make models for use of alternative sources of energy

Children from 500 schools exhibited models

Creative young scientists, created innovative scientific models which aimed towards a greener and eco-friendly future, at 'Inspire Awards - Science Expo,' held at Pilikula Nisargadhama in Mangalore on Monday.

The second phase of the district-level exhibition that had kicked off on Saturday, was inaugurated on Monday. As many as 500 high school and primary school students from Sullia and Mangalore taluk partook in the expo,  jointly organised by the Public Instructions Department, District Institute for Education and Training and Pilikula Regional Science Centre.

Most of the students, displayed working models of usage of alternative energy  in everyday life and also explained the audience, their benefits.

Speaking to Deccan Herald, Rahil R Sayyed from Infant Jesus Joyland said that electricity can be tapped from the small waterfalls in the district using a turbine. This can be used to light street lights or houses in nearby areas, he said. On the other hand, Elton D'Souza from Vidya Jyothi Higher Primary School was explaining on how energy is created using wind turbine.

Charan M G from Blessed Kuriakose English Medium School (Sullia) had created a 'non fuel super pump'. Using a bicycle energy, he explained mechanical energy being transferred to pump water from a well.

Lavanya from Sarojini Madhusudhan Kushe School had created a natural refrigerator using bamboo sticks, clay pots and wet sand. She explained on how food can be stored in an clay pot at a low temperature, using natural resources.

Another student, Mohammed had created a gas sensor. "Whenever gas leaks, the electricity passage in the house is automatically blocked. This can avoid mishaps," he said.

Kavya from St Anne English Medium School had created a quiz board. She was asking audience to match answers to various questions on the board. If the answers were right, bulbs on the board would glow. She later explained that she had created the board using electric circuits.

On oil skimmer, Mokshitha from Government School Mallali said that she can separate oil mixed in water, using a rubber belt, mortar and battery eliminator.

Student Naimisha Shetty, revealed the secret of nature's beauty using Fibonacci series application. She explained that body structure of human beings, plants, animals and natural phenomena like hurricane and milky way galaxy all come under a golden ratio. Hence, they look aesthetic.

Natesh had come up with a model solar house, with a working fan and light. He explained that solar energy that falls on a silicon plate, converts into electricity. "If all use solar energy, then we can solve power crisis," he said.

Kiranchand from G U H P School had created a 'Hydraulic JCB' that works on Bernoulli theorem.

Praveen from Government High School Kalladi, explained that power can be saved using the 'Light depending on resistance' model. Here, street lights would automatically switch on, sensing the absence of light and would turn off, when light is present, he said.

Nodal Officer for the exhibition Dayavathi said that the expo will be held till July 25 and about 1,500 students are expected to take part. Students who win in the district-level, would go to the state-level expo to be held in August. The third phase of the expo for Bantwal, Belthangady and Moodbidre would start on July 24, she said. DIET Principal Palakshappa D inspected the science models.
