March 14th...giornata della matematica, Pi Greco day. Perchè non utilizzare le cifre di π per costruire una spirale, la spirale di Archimede, da appendere in classe o nel corridoio? Se appesa sopra un termosifone o un'altra fonte di calore, diventa una divertente attività ed esperimento con cui scoprire alcune caratteristiche dell'aria: la spirale ruota e si muove perchè spostata dall'aria calda. L’aria calda è più leggera dell’aria fredda perché meno densa e sale verso l’alto. https://maestramonica.it/pi-greco-day-la-spirale-di-archimede-matematica/
