Seeing vibrations

We can directly see things vibrating or we can feel the vibrations by touching things. Let's do an activity to see vibrations when we create a sound.
1.6
Activity: Dancing rings on the base of the cup

Materials Required:
1. Paper cup
2. Straw   
3. Scissors                                                                      

   
Procedure:  
1. Cut a straw to get rings (as shown in the figure)
2. Hold a paper cup in an inverted position
3. Now put the rings on the base of the paper cup                                              

4. Hold the cup with both hands close to the mouth and shout into it.    

Why do the straw rings jump around?

You can feel vibrations by touching. You can do this using the paper cup. Hold the paper cup with the open end close to your mouth. Ask your friend to touch the base of the cup. Now shout into the cup.

You can also feel the vibration of your voice. Place your fingers gently against your throat and say ‘aaaahhh’ or ‘hmmmm’ or ‘hooooo’ or any sound- and say it a little loudly.
