The UMass Lowell Engaging Computing Group will host a free dinner meeting for teachers on April 16, 5-7PM, to explain the Science of Rivers field trips that are available in May and June for science/biology students in Grades 6-12. Funding is available for the field-trip program and bus transportation. These one-day field trips on the Merrimack River focus on water-quality testing and use iSENSE, a free, web-based tool for collaborative data analysis. Teachers will conduct a classroom activity using iSENSE prior to the field trip.
