PHOTOS: Upper School and Kindergarten Students Come Together for Engaging Earth Science Activity

Who knew an Oreo cookie, some sand, vinegar and baking soda could make for a fun and educational activity between kindergarten students and Upper School AP environmental science students?
It was just the right ingredients for an hour of fun, as the older Tartans made their way over to the Lower School Outdoor Classroom for a little lesson on how the Earth works. Using an Oreo cookie, the older students gave a basic demonstration on how plate tectonics work (and sometimes can cause earthquakes!)
Then, the students went over to the sand pit, where they demonstrated lava flows of volcanoes by building a mountain out of sand, adding a cup of baking soda to the caldera and then pouring vinegar in. Before the chemical reaction of baking soda and vinegar caused an “eruption,” the kindergarten students hypothesized where the lava would flow and explained to the Upper School students why. 
This is the second year that AP environmental science students, taught by Edmund Herlihy, have visited the Lower School for a fun earth science lesson. It is one of many cross-divisional activities that St. Margaret’s professional community plans throughout the year, as a way to further absorb learning and have cherished connections between younger and older Tartans.
