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/

Bumphead parrotfish are fantastic fish to watch. You can see them while scuba diving or snorkelling. If they are feeding you can often hear their huge teeth crunching on rocks and corals! These bumphead parrotfish were filmed in Misool in the southern part of Raja Ampat.
