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/

Tribute to Mama Piru. «An incredible woman and ambassador of the Race for Water foundation left us. I met Mama Piru during our first odyssey in May 2015 when we came to study the marin plastic wastes on the Island of the Rapa Nui. She quickly opened her doors and gave her trust. She is a leader who dedicated her life to preserve the heritage, the culture and the environment of the Island. An engaging person, animated by a strength and faithless. She fought everyday to improve the Rapa Nui conditions. She stand for her people in front of the United Nations and the brought together people. Mama Riu will stay in our heart forever. What a joy to have met her and gain her trust. A heartfelt thanks to you, Mama Piru. » Marco Simeoni. The Race for Water Foundation is dedicated to the preservation of the water and the oceans in particular. Today, seriously under threat from plastic pollution, it is imperative that this essential resource for life is protected.To prevent plastic waste from reaching the waterways and oceans by developing social models and business models that give value to plastic waste and hence encourage its collection.
