Black Hill Partnership Blog
In the fall of 2015, Barnesville embarked on a school-wide partnership with Black Hill Regional Park to enhance outdoor and environmental education across the School’s curriculum. This blog chronicles related programs and activities.
Barnesville's 7th graders released 37 Golden Rainbow Trout fingerlings into Little Seneca Creek. The students raised the fish from eggs and have cared for them in the classroom since December 2016. They monitored the water chemistry of the tank and changed the water as needed as they observed the growth of the trout. The trout unit is a part of the life science curriculum.
On the day of the release, Middle School Science Teacher Mrs. Farah and the seventh graders met Black Hill Naturalist Katrina Fauss at Little Seneca Creek Park. The students individually counted and released the fingerlings. Then, they hiked back upstream and Ms. Katrina led them in a benthic macroinvertebrate sampling lab.
A benthic macroinvertebrate is a spineless organism that lives at the bottom of a stream or creek. They are an indicator species that scientists can use to determine the health of a stream ecosystem. The students were first briefed on the types of invertebrates they could expect to find and provided with dichotomous keys to aid in identification. Next, they waded into the creek to disturb the creek bottom whiling using nets to collect the organisms that became dislodged. Sampling took about an hour, but when the class was finished, they had larva from crane flies, mayflies, and dragonflies, 2 crayfish, 2 types of fish, and numerous snails. They even found some salamander eggs.
“The amount and diversity of the invertebrates they found demonstrated a very healthy stream environment for our trout,” said Mrs. Farah.
Students also tested the water for ammonia, nitrates, and pH level. They compared the stream data with the data the were previously monitoring in the tank. Some of the students were impressed that, while we were constantly adjusting chemicals to maintain the water quality of the tank, the stream data was perfectly balanced, without outside help.Trout in the Classroom (TIC) is a hands-on environmental program in which students raise trout from eggs to fingerling, manage chilled tank water quality, engage in stream habitat study, learn to appreciate water resources, develop a conservation ethic, and are taught to understand ecosystem connectivity.
