Class three student Hanjala does not like this city. As he comes from his house to school from Paikpara to Mohammadpur, two things disturb him a lot: traffic jam and bad waste management.

“The city is dirty,” he said, adding mismanagement as a leading cause to the city’s pollution.

As he goes to school every day, Hanjala plans to make a modern city where almost everything was properly managed. He shared this idea with his friend Steve Probal Shanjal and found that Steve also felt the same.

Both of them made a model of a modern city and presented it in the Annual Science Fair 2014 at St. Joseph Higher Secondary School, which was inaugurated yesterday.

In their project, the roads are wide, footpaths are not occupied and vehicles are running in an organised way.

Talking to the Dhaka Tribune, Hanjala said: “I want to be an urban planner in future and I want to solve the problems of this city.”

Around 460 other projects were presented in the fair, along with a total of 750 scrap books. Students of 50 schools took part in the fair. This year, the theme of the fair was “Role of Science in Human Resource Development and Economic Prosperity.” The three-day long fair is scheduled to end tomorrow.

Students, especially from Class III and IV, were seen enthusiastically participating and presenting their projects.

A good number of projects were seen on city management, hanging bridges and waste management.

Class three student Nafees Abrar Islam presented a waste power plant in which waste will be used to produce power. Talking to the Dhaka Tribune, he said a project in Discovery Channel inspired him to come up with this in the fair.

Artijwa Prothian Abdel presented a solar copter, where solar power would be used to run a helicopter. He said he wanted to be a scientist. Another class III student Safwan Uddin presented a model for a windmill.

Addressing the inaugural programme, Director of Bangladesh Academy of Sciences MA Mazed urged the students to acquire knowledge in the field of science and use them for the betterment of the country. He said he believed the young scientists would help the country to reach its ultimate goals.

University of Liberal Arts Bangladesh Pro Vice-Chancellor HM Jahirul Haque said: “Though we live in a technology driven society, the number of students who pursue science and engineering for higher studies is substantially decreasing.”

He also said platforms were needed which would help nourish and stimulate scientific minds.
