As you may have seen in our Spring newsletter, since 2013 we have been working with the Pittsburgh Parks Conservancy (PPC) on a grant received from the National Fish and Wildlife Foundation’s Five Star and Urban Waters Restoration Program. One of the goals of our partnership on this grant was to develop a culture of stewardship for the Nine Mile Run watershed by engaging a wide range of ages in citizen science and stewardship activities. One way we approached this was to implement PPC’s Mission Ground Truth (MGT) program at Wilkinsburg Middle School.
MGT is an interdisciplinary ecosystem assessment program mapped to PA state academic standards for 7th and 8th grade students that includes in-class discovery activities as well as a field trip to Frick Park. During the field trip, students get to be ecologists for the day, and have the opportunity to use the same tools and sampling methods that scientists use to evaluate the health of forest and stream ecosystems.
Recently, NMRWA staff worked for two days in Frick Park with Environmental Educators from PPC to help lead the Wilkinsburg Middle School students through the field day programming.
We began each morning by discussing goals for the day, then broke into small groups. During the morning session, the groups each explored a section of the Fern Hollow stream while discussing questions such as “how can ecologists detect and measure pollution in a stream?” and “what benefits do humans and animals get from streams?” Then the students recorded data on physical and chemical water quality characteristics, such as temperature, pH, dissolved oxygen, conductivity, and velocity. Next, we explored the benthic macroinvertebrate populations by carefully overturning rocks and collecting samples using a net. To wrap up, we would discuss how everything tied together by asking questions like “based on the data we collected, is the stream healthy or unhealthy?“and “how does the quality of Fern Hollow affect the health of Nine Mile Run?”
After a break for lunch, the students got to venture into the forest for a deeper look at the complex forest ecology present in Frick Park. We identified different tree and plant species and talked about the various ecosystem services that forests provide to animals, streams, and people. We asked questions like “why is biodiversity important in forests?” and “how is the health of this forest related to the health of Fern Hollow and Nine Mile Run?” Then the students used forestry tools to collect data on the location, size, and type of trees, and we looked for evidence of Asian long-horned beetles. To wrap up, we asked questions similar to the morning session, like “is this section of the forest healthy or unhealthy?”
Over the course of the two days, we had a wonderful & enriching experience working with the students and with the PPC staff. Thank you to Mike, Taiji, Steve, and Chelsea for their expertise & enthusiasm in implementing the MGT programming!
