On Tuesday, October 28th, 2014, a group from the Swarthmore College Department of Chemistry and Biochemistry visited a 5th grade class at a nearby elementary school. The 5th graders learned about acid rain and its impact on the environment. In addition to a class discussion, all the students engaged in hands-on experiments where they tested how the geology of a lake can change the impact acid rain has on the ecosystem of a lake. Professor Kathleen Howard led the lesson and hands-on activities. Swarthmore students Martin Mathay ’15 and Bryan Green ’16 provided enthusiastic assistance.
