Four Nigerian secondary schools will be representing the country in the forthcoming International Science Fair slated for Brazil and Slovakia in October.

Our correspondent reports that the fair would enable the schools to showcase their scientific inventions and projects.

It was gathered that the four schools include the Government Day Secondary School (GDSS), Wuse 11, and the School For The Gifted, Gwagwalada all in Abuja.

Others are the Solid Rock International School, Lafia and the Government Science Technical College, Garki, Abuja.

They emerged winners after contesting with other selected schools across the nation and they will represent the country in Brazil and Slovakia in October in the fair tagged: “Mostratee”.

GDSS emerged the overall winner with its invention of insect repellant, organic flea spray for animals and tea, all made from orange peels, as well as dye made from the Hibiscus flower.

Solid Rock International School Lafia also won with its remote controlled car jack and GSM – based home automation system for turning off home appliance even when away from the house.

The remote controlled car jack designed to run on batteries will be powered by direct infrared rays from any remote control.

The Government Scence Technical College won with its bio-fuel for powering generators, sourced from the vapour of fermented maize water after undergoing heating at 75 Degree Celsius.

The School For The Gifted Gwagwalada, also won with its healthy earth sustaining system made from the components of a car battery, which produces hydrogen to combat the depletion of the Ozone layer.

The contest was organised by the Society for the Promotion of Science and Technology in collaboration with the FCT Agency for Science and Technology.

The aim of the contest is to build the capacity of Nigerian students in Science and Technology.

The coordinator of the competition in Nigeria. Mr. Desmond Achoakawa, said that the fair was a competition for secondary schools aimed at selecting schools that would represent Nigeria in the International Science Fair.

He said that Nigeria had come first in two of the international fairs since the country started competing in 2007.

“In 2009 and 2010, we came first in the international competition and each competition usually has up to 40 countries competing,” he said.

He said that the organisation had been finding it difficult sponsoring the event due to the lack of regular sponsorships and collaboration from both the government and the private sector.

Mr. Guregi Ibrahim, head of Popularisation of Science, Agriculture and Biotechnology, FCT Agency for Science, said that the competition would help the development of science in Nigerian schools.

He said that such competitions would help in sharpening the intellects of the students and enable them contribute meaningfully to changing the world.
