On Day 152 of the school year – with only two days to go – students are by this time very much in their element in chemistry class. Juniors Gabe Sims, Chris Ross, Matthew Ward, and Alex Stapp show great ease in navigating the acid/base titration lab for their teacher, Mr. Peter Muller ’81. The state-of-the-art labs were part of a plan to overhaul the science facilities beginning with the 2002 renovations of the third floor labs and completed in 2008-2009 with the four labs on the fourth floor.
