The Anna Science Centre-Planetarium in the city will organise a mathematical model making exhibition-cum-competition for schoolchildren on January 22 and 23.
The competition will be organised in two categories — one for children of class 6 to 8 and the other for students of class 9 to 11. Participants have to make a physical model to explain the theory, concept or formula, and explain the same to visitors. Each school can nominate one student per category on or before January 20. Three prizes will be awarded in each category, I.K. Lenin Tamil Kovan, Project Director (in-charge), Anna Science Centre Planetarium, said in a release.
