Goodbye Honey Buckets
Students investigate arctic geology and hydrology as well as tundra ecology as they consider options for sewage treatment. Public safety, environmental impact, and issues of construction and engineering be explored.
Curated OER
Home, Home on the River
Students examine the complex issues that result from human use of ecologically sensitive areas. They investigate these issues from the point of view of their major/career path.
Curated OER
Water Quality
Students use a microcomputer connected to a conductivity probe to measure the total dissolved solids in local area water samples. Students then compare their measurements with others in their class as well as other standard measurements.
