C V Raman was also awarded the Nobel Prize in Physics in the year 1930 for his invention.
 
 
Pratham celebrated the National Science Day this year Mega Science Fairs, workshops, and various other activities were organized in a weeklong celebration.
 
 
For a science fair, 'Vigyan Mitra' selects children from a school and trains them to perform different activities and models. These children are called as 'Bal Vigyan Mitra'. Bal Vigyan Mitra on the day of the fair explains the experiments and models they learned or made, to teachers fellow students, parents and other members from community. Science Fair enables children to enhance their demonstration skills and also develops a platform to showcase the wonders of science.
 
 
Mega Science Fair was the major activity for National Science Day celebration. In a Mega Science Fair, more than 40 models and experiments are demonstrated and more than 50 Bal Vigyan Mitras are trained. Mega Science Fair was organized in schools, communities and science centers according to the location. Government officials, locals, parents, schools were all invited to be a part of the event. Children explained a variety of models and experiments ranging from Newton's disc to solar and lunar eclipses
 
 
Pratham's Science Learning Program apart from working in schools and communities has established science exploratory in multiple locations. These act as a platform for children to come learn and explore more in the field of science. Certain number of children regularly visits the exploratory. This year a project competition was assigned to them on the theme 'Energy Conservation'. Children came out with new ideas and displayed their work with great enthusiasm. Team's main focus was on mobilization to ensure maximum community involvement. Rallies were organized as a part of it. Banners, posters, and pamphlets were distributed and displayed. Nearly 3000 Bal Vigyan Mitras were trained and more than 27,000 people including children and elders visited the event.
