During an APES lab on acid rain, juniors Victoria Escandell and Liz Schmidt direct smoke from a match into a test tube coated with an indicator fluid. “When I lit the match under the test tube, the test tube collected so much smoke, and then when I looked at it I was like, ‘I wonder what this smells like,’ so I sniffed it and inhaled a lot of smoke,” senior Jessica Blanco said. “This is why I’m going to be a great biochem major.” Students observed how the sulfur-containing smoke caused the indicator fluid to grow more acidic.
