The 38th Kendriya Vidyalaya Sangathan (KVS) Regional Science Exhibition took off at Kendriya Vidyalaya Pattom in the city on Wednesday.
As many as 600 students representing 60 schools from the KVS Chennai region are participating in the two-day exhibition titled ‘Science and technology for challenges in life.’
Chief Conservator of Forest K.P. Ouseph inaugurated the exhibition at a function presided over by KV Pattom Principal C.P. Kumaran.
The exhibition includes static and working models prepared by high school and higher secondary school students in six different sub-themes including biodiversity, agriculture, green energy, transport and communication, community health and environment and mathematical modelling.
