Fluorescence Rocks! Exploring Glowing Sodalite

Syenite rocks containing sodalite that fluoresce yellow have been found on Lake Superior beaches in recent years and are of interest to collectors. The fluorescence of this mineral, which can be found in other localities, can be shown in classrooms and studied spectroscopically. Its structure can also be modeled with LEGO bricks, enabling further classroom connections.
