New School Montessori 4th, 5th and 6th graders are studying the elements in their physical science class. Teacher Casey Rodriguez is pictured here Murray, showcasing their cool science t-shirts of the Periodic Table of Elements. Biso and Sami demonstrated Bohr’s Model, placing protons (green), neutrons (blue) and electrons (yellow) for several elements. Biso’s favorite element is oxygen with its 8/8/8 of each colored marble. Biso pointed out that the elements moscovium and flerovium would require a lot more marbles with each having about 115 protons and electrons and about 175 neutrons. Now THATS a lot of marbles!
