Jumping Rice(Class III)

 Students of Class III observed vibrations passes from one medium to another through the activity of Jumping rice . Students used few Rice grains and put them on a jar covered with plastic and by tapping on the jar the students could observe the rice grain vibrating at different speed depending on the tap on the jar (gentle or hard).Also the students observed that taping a plate or any object next to the jar also caused vibrations and led to movement of Rice.
