The students from all the four branches of Viqarunnisa Noon School and College are participating at the four-day fair where 285 projects were put on display.

Vice Chancellor of Southeast University Dr M Shamsher Ali formally inaugurated the fair yesterday.

The students from class V to XII stormed their brains to invent ways to make best use of science, solve various problems of life and make life easier using science. The projects conceptualised by the young scientists represent their innovative minds and interest to science.

They have displayed arsenic water purification plant, some tried to solve problem of global warming while some have sorted out ways to make Dhaka free from traffic jam and many more.

A project by a group of students of class VII- Mridula, Irina, Promi and Roshni- focuses on the safety issue of passenger launches using their invented device.

The device would measure the level of the lower portion of a launch dipping under water and will give alarm when the level goes down crossing safety mark.

"With loading of extra passengers or weight more than capacity the lower level of the launch will go under water crossing safety level and the device will show red light in that case," described Mridula, one of the members of the group.

The organisers arranged a sky observation session yesterday evening with technical support from Bangladesh Astronomical Society.

The fair will remain open for the visitors everyday from 9:00am to 5:00pm till February 19.
