With the objective to provide a forum for children to pursue their natural curiosity, creativity, innovation and inventiveness, the NCERT has organised Jawaharlal Nehru National Science, Mathematics and Environment Exhibition (JNNSMEE) every year since 1971. The exhibition is one of the biggest platforms for children from various schools in India to showcase their talents in science and mathematics, and their applications in different areas related to our everyday life. NCERT organises the exhibition in two phases. In the first phase, the children from all schools in the states participate at the State Level Exhibitions. The States then send their selected entries to NCERT for consideration for participation in the National Level Exhibition. In the second or final phase, NCERT organizes the National Level Exhibition: Jawaharlal Nehru National Science, Mathematics and Environment Exhibition (JNNSMEE) for Children. From the selected entries submitted by the States, NCERT selects the best exhibits for the National Level Exhibition and invites them for the participation at the JNNSMEE. The theme for JNNSMEE-2021 is Technology and Toys. The organization of this exhibition envisages that children and teachers would try to analyze all aspects of human endeavour with a view to identify where and how the new researches and developments in science, mathematics, technology and environment can bring and sustain progress of society leading to improvement of life.
