3.2 Teachers' Note

Singing spoon is a very nice activity to do. If you do  this activity you can listen an enchanting voice similar to a temple bell which vibrates for longer time. The vibrations of spoon can be heard for longer time because sound wave with small amplitude travels to our ear via string. We won't be able to listen the small amplitude sound if there is no string. String provide a pathway to send sound wave of small amplitude to us.

This activity is mainly to show that sound travels through solids (here string). But
enchanting singing of spoon make it very interesting. Let the student have fun with this activity.

Ask them to answer and discuss the questions asked in this section.
