Dear Papa and Nana,
I'm going to talk about what I have learnt about sound.
First of all sound is energy, like light or electricity.
Sound vibrations travel in waves by pushing air molecules. You might ask- what are molecules? They are little circles that are in the air you can't see them because they are invisible and they’re all around us. Vibrations can be powerful. The stronger the vibrations,the louder the sound. Sounds are created when something vibrates, sending waves of vibration into the ears.
