Glimpses of session:
100 children from AMC schools visited IITGn today. They had a wonderful time making tangram, gliders and learning about the ultrasonic sensor and its working! Have a look at the glimpses of the session.
After the session one of the child made a sheet of t-shirt out of the paper and showed me! Then we had tour campus and children really liked the library 🙂
