Addressing the event's curtain-raiser here, the Science and Technology minister termed IISF a medium to encourage young minds towards the field of Science.
"The fourth edition of the festival is also a tribute to former prime minister late Atal Bihari Vajpayee who brought Science to the national stage," he said.

The Global Indian Science & Technology Stakeholders Meet (GIST), Industry-Academia Meet and Science & Technology for Harnessing Innovations (SATHI), a national startup entrepreneurship summit and Student Science Village are some of the special events.
"The Science Village programme is linked with the 'Pradhan Mantri Sansad Adarsh Gram Yojana' to reach out to the rural masses and propagate Science, and for seeking scientific solutions to the diverse challenges facing our society, particularly rural India," Vardhan said.
Speaking on the occasion, Secretary, Department of Biotechnology, Renu Swaroop said the role of 'Women Scientists and Entrepreneurs' in shaping the scientific growth trajectory will be another highlight of the festival.
In IISF 2018, a world record attempt will be made to "isolate DNA" by 500 students from classes VIII to X.
