This week we are investigating the line of inquiry "How sounds are created and heard"
"SOUND IS VIBRATION"
"What is vibration?" the children had no idea.
To understand the meaning of vibration we conducted many experiments:
1) make a vibration board: the children helped to hammer 4 nails onto a board and stretched two elastics across. When the elastics were plucked they vibrated!
2) place rice on a drum and band a pot loudly beside to watch the rice vibrate on the drum
3) touch your larynx and feel the vibrations
4) hold a balloon next to your mouth and say "Aahhhh" and feel the balloon vibrate
To gain insight into the children's understanding of sound we played a sorting game with picture cards: things that make sound and things that don't
I always love when I bring an activity with a predicted outcome and the children's perspective changes my thinking! The children had their own ideas about what things make sound:
"A bed squeaks!" - Kai
"Grapes crunch with your teeth" - Natalya
"A pear crunches"- Chloe
