On August 7th, students from Vermont Adult Learning in St. Albans took their education outdoors with a hands-on investigation at Lake Carmi, focusing on water quality and the challenges posed by cyanobacteria.
“Lake Carmi provided a living laboratory for students,” said Kristy Hancox, teacher. “By testing water quality and discussing molecular processes, students connected abstract scientific concepts to issues that affect their own community.”
While visiting, students were also able to enjoy local wildlife, walking trails, lake-side snacks, and a visit to the nature center, where they spoke to park interpreters – park staff solely dedicated to helping visitors learn more about the natural and cultural history of the park – in order to gain insight and knowledge about the impact of lake quality on wildlife species and humans.
After the trip, learners got to roll up their sleeves and dive into lab work back in the classroom. Using the water samples they collected at the lake, students tested for pH, dissolved oxygen, and clarity to learn more about the lake’s health.
They also discovered how tiny molecules like oxygen, nitrogen, and phosphorus play a big role in water quality and can even lead to cyanobacteria blooms. By looking at molecular structures tied to photosynthesis and toxin production, students made connections between what they saw at the lake and the science happening at the microscopic level.
The follow-up made science feel real—showing how a field trip can lead to hands-on experiments that connect the classroom to the community.
This field trip was made possible through passes generously provided by Vermont Parks Foreverand transportation assistance through a Vermont Humanities Rapid Response Grant. Their generous support ensured all students could take part in this place-based learning experience.
