An estimated 150 students from various schools assembled at the Birla Industrial & Technological Museum (BITM) to observe the day, organisers said.
The students drew paintings to promote consciousness on sustainable natural environment at the programme organised by The Bengal Chamber of Commerce and Industry.
At the Indian Museum here, a workshop was organised where rural artisans showed how to make jewellery using palm leaves and natural fibre.
Students also sketched posters calling for Environment Literacy and attended a presentation 'Environment and Climate Literacy' at the Museum.
