Sriram Bhimaraju, who will enter grade 7 in the fall, was today named a finalist in the Discovery Education 3M 2018 Young Scientist Challenge! Every year, students in grades 5-8 submit videos for the competition, in which they detail a scientific solution they have devised to an existing problem. Bhimaraju developed a smartphone app that helps archers improve their aim with the aid of a Bluetooth sensor. In his video, Bhimaraju explains how he used Hooke’s Law and several formulas to calculate how various factors affect an arrow’s trajectory when shot from a bow, and how he utilized the smartphone’s gyroscope and accelerometer to help archers reach the optimal form. The final stage of the competition is set to take place Oct. 15-16 at 3M’s headquarters in Maplewood, Minn.
