Adventures in STEM: Lessons in Water Chemistry From Elementary School to Graduate School
Abstract:
3rd-5th grade field hikes – While helping at Jamestown Elementary School, I led hikes with a 3-5th grade class to an abandoned flourospar mine where the students were able to pick up beautiful purple fluorite crystals from the ground while discussing how mining works. During the hike back, we used field meters to measure the pH and conductivity of the stream and discussed the need to balance society’s need for metals with the harmful effects of acid mine drainage.
9th, 10th grade STEM Academy at Skyline High School – During an NSF-sponsored fellowship, I had the opportunity to teach a STEM class to 9th and 10th graders where we used the engineering design process to a) design a tool to help a handicapped 3rd grader use the drinking fountain by herself and b) design a treatment system for cleaning up acid mine drainage.
Undergraduate and Graduate Environmental Water Chemistry Field Trip – Students had the opportunity to tour two local mine sites to collect contaminated water that would be used in class for alkalinity titrations and pH, sulfate, and hardness measurements. They also collected water samples upstream and at multiple points downstream of a wastewater treatment plan and measured and graphed the dissolved oxygen “sag” in the river.
