In this Interdisciplinary Field Investigation middle schoolers will combine science, math, geography, creative writing and art. The setting will be a local stream (site yet to be determined, Minnehaha or Vermillion) where 150 students will rotate through 5 stations. The science station will provide middle schoolers with an inquiry-based approach to determine the discharge of the stream. Students will not be told how to do this; instead they will make observations and estimate stream discharge using their own problem solving skills.
