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/

The Scandinavian marine industry produces boats that are practical for its own distinct waters, which just happen to be extremely popular elsewhere as well. Aboard the Ocean Master 630, boats.com reviewer Alex Smith describes the stern anchor locker, the bow step to enable mooring bows-to and the space and comfort of this 'driving machine'. Click on the video to watch for yourself. http://uk.boats.com/boat-content/2013/11/ocean-master-630-first-look-video/ For more boat videos, visit uk.boats.com.
