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/

Hey, did you know that #triggerfish are pretty feisty #creatures? They get really protective of their homes, which they make by biting at stuff like rocks and #coral. So, if you accidentally swim too close to their nest while diving, they might mistake you for a threat and start showing defensive behaviour! But don't worry, once you're out of their turf, they'll usually chill out and leave you alone. Ready to meet this little feisty #fish #undersea?
