Long Term Monitoring Of Grand Ravines Park Restoration: An Authentic Research Opportunity For Jenison High School Students And Beyond, Karina C. White
Long Term Monitoring Of Grand Ravines Park Restoration: An Authentic Research Opportunity For Jenison High School Students And Beyond, Karina C. White
Culminating Experience Projects
Access to authentic research is limited at the 7-12 science education level. At the same time, many local restoration projects would benefit from, but don’t have access to a long-term system of monitoring. This project seeks to unite those two needs by developing a protocol for 7-12 classrooms to be able to participate in authentic research through long-term monitoring of a local restoration project. The protocol developed in this project was used by Jenison High School students at Grand Ravines Park. Grand Ravines Park is a recently acquired Ottawa County park with a history of anthropogenic disturbances. Shortly after the …

The Impacts Of Road Salt On Water Quality And Phosphorus Dynamics In An Urban Lake, Ellen Foley
Masters Theses
Road salt runoff from de-icing applications has notably increased chloride concentrations in lakes throughout north temperate regions of the planet, with negative impacts on freshwater ecosystems. For the past 20 months, I have monitored the water quality of a chloride-impaired lake and associated tributary in Grand Rapids, Michigan. Chloride levels in the deepest part of the lake have reached up to 331 mg/L, above EPA chronic toxicity thresholds. The salt-induced density gradient has prevented the lake from completely mixing during my study period and created persistent hypoxia in the hypolimnion. Total phosphorus (TP) concentrations in the hypolimnion can exceed 7500 …
