Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Mrs. Moore’s third grade class wants to go on a field trip to the science museum. * The cost of the trip is \$245. * The class can earn money by runnin...

By far most field trips in structural geology and regional tectonics do NOT take place in large urban centers with a trip focus on mitigation of hazards. What is described here is an example of the instructional and learning opportunities associated with active tectonic examination of large population centers.

Alternative futures studies are a valuable yet resource-intensive way in which environmental scientists try to conduct informed debates about policies for specific geographic regions. These studies require modeling what the future would look like if different stakeholder groups had their way. The modeling is carried out by applying historical trend data to future projections that are rooted in the preferences of the different groups. Alternative future studies can be controversial due to the limitations of modeling and to the extent to which the models represent fully the different possible scenarios. Yet, they can be especially valuable for decision making about which areas in the region would be most appropriate and most acceptable for the applications of different policies such as development and restoration. Through a series of hands-on classroom activities that are the culmination of a variety of field trips, case studies, and analyses of GIS data about river systems and river restoration options, the students build deep understanding about what alternative futures studies entail and what are the applications of such studies to specific rivers in the Puget Sound area.

During a lab period, students go out in the field to an area that contains at least 2 fault/fracture sets. Students measure orientations of faults and make observations about the relationship between different fault sets. After the field trip, the students compile their field data, plot it on a stereonet and write-up a brief report. In this report students will use their field observations and stereonet patterns to determine whether faults are related or unrelated to each other.

During a previous field trip to a local stream, students examine the stream and flood plain, evaluate evidence for high-discharge events, measure discharge, see the USGS gauging station for the stream and examine historical discharge records. Then, to prepare for hometown stream exercise, students chose a stream of personal interest to them and with at least 30 years of NWIS discharge data, and also gather personal knowledge and background information about their stream. The instructor uses Stony Brook data to model the project by downloading NWIS discharge data and using the data to a) describe the typical annual pattern of discharge, b) graphpeak annual discharge for the years of record, c) making a flood frequency graph and d) integrating background information into an analysis of the stream's discharge. Students then do this for their own streams. The activity involves students in accessing and analyzing real data, integrating background information into a technical analysis. They also gain experience with Microsoft Excel and via other students' work, learn about streams that can be quite different from their own.

During the course of the day, students examine the high-grade metasupracrustal rocks, related gneisses, and the late Archean granitoids and mafic dikes. We have prepared a number of exercises that might be done with classes at different levels. Depending on the background and preparation of your class you might want to emphasize different learning skills specific to the class level: observation, interpretation, integration (i.e. multiple lines of evidence focused on a given problem), and synthesis (i.e. relationship to the "big picture", drawing from the corpus of geologic knowledge). We have also prepared a compilation of our key scientific results, but these are under seal and we'd like you to do the exercises first as if you were students before taking a look at the supporting evidence.

To prepare for this activity, students receive background on bedforms and flow regimes in class and practice identifying and classifying bedforms from field photographs. Students are then given a map of a barrier beach/inlet/tidal delta complex in mid-coast Maine and asked to predict what bedforms they expect to find in specific sub-environments. During a subsequent field trip to the area, students observe, classify and map bedforms and relate them qualitatively to formative flows. Qualitative description and classification are supplemented by quantitative measurements of bedform morphology and orientation, and by GPS-located digital photographs. After the trip, students compare their predictions and observations of bedforms in the sub-environments, reflecting on the reasons for the differences and the evolution of their thinking. The exercise also serves to set the stage for subsequent quantitative studies of bedforms and bedload transport, as well as interpretation of sedimentary structures and clastic depositional environments in the geological record.
