2. Make a list of sounds you hear in your surroundings.

3. Take a rubber band. Put it around the longer side of a pencil box. Insert two pencils between the box and the stretched rubber. Now, pluck the rubber band somewhere in the middle. Do you hear any sound? Does the band vibrate?

3. Take a metal dish. Pour water in it. Strike it at its edge by a spoon. Do you hear a sound? Again strike the plate and then touch it. Can you feel the dish vibrating? Strike the dish again. Look at the surface of water. Do you see any waves there? Now hold the dish. What change do you observe on the surface of water? Can you explain the change? Is there a hint to connect sound with the vibrations of a body?
