Innovative work Phase 2
INNOVATIVE WORK
On 20th January 2025, I took a lesson on propagation of sound in class 8 from the unit sound. The first activity of the lesson started with the participation of students followed by the innovative experiment. A set of identical pingpong balls were tethered from uniform strings of same length, supported using a wooden stand. I set tuning forks of different frequencies into vibration and when the tuning fork is made in contact with one of the balls at the end, the sound waves from one end of the ball travels to the farther end. So sound waves can travel through air.
This idea was tested by students too. They got chance for hands on experiences and the model enhanced curiosity among students.
