In Part 1 of this unit, students will develop protocols for the collection of sensory data to address a guiding question. The data collected will consist of scents or sounds. The advantage of using sensory data is that students are equipped with the analytical equipment (ears and nose) and are familiar with its use. However, students may not have taken the time to consider the variety of perceptions that occur within a group of people who are sharing a sensory experience and the impact that variation can have when attempting to collect objective data to help characterize environmental problems.
Protocols are necessary to ensure consistency of data between collection points and between data collectors, and to link data collected to a research question. Protocols also serve as a record of the methodology used by an investigator that may be subject to scrutiny by subsequent data users or by anyone reading or using a report containing the data. Data collection in all scientific fields may be collected using protocols common within the field or developed by an investigator for use in a specific study.
Because sensory data is inherently qualitative and subjective, students will need to develop methods of quantification that ensure as much objectivity as possible. Likewise, scientists collecting field data may need to develop unique protocols that ensure that field data is collected in as objective a manner as possible.
Ideally, the unit will span two class sessions to allow for the gradual development of a data collection protocol and field plan.

In Part 2 of this unit, student groups will plan and execute the field collection of sensory data (scents and/or sounds) using previously developed data collection protocols. The advantage of using sensory data is that students are equipped with the analytical equipment (ears and nose) and are familiar with its use.
Class time will be devoted to developing a field investigation plan. Students will create guiding questions and choose a study area, develop or obtain maps of the study area, assign field roles to group members, and develop a timeline for completion of fieldwork. The plan will need to ensure proper execution of data collection protocol, a clear record of the data collected, and a record of field conditions.
Careful planning of fieldwork is important to ensure that the time in the field is utilized efficiently and effectively and that the data collected meets the intended requirements. Likewise, an environmental professional (such as a geoscientist) undertaking an environmental investigation would need to develop a field investigation plan to meet the needs of the investigation.

In this unit, students will be introduced to different data types used in the geosciences and other disciplines to understand environmental problems. The instructor will discuss the difference between qualitative and quantitative. Then, students will be given data sets related to water in Phoenix, Arizona. Students will work in groups of two to five to categorize different data sets as qualitative or quantitative and to reflect on their emotive responses to different data. The session ends with a discussion about the potential uses of these various data sets in decision-making around water in Phoenix, and uses this to foster a discussion about the ways in which different data sources lend insight into complex system problems.

In this unit, students will keep a log of immediate, personal sensory experiences by pausing once each hour over a period of ten hours and recording the sights, sounds, smells, tastes, and tactile experiences they are sensing at that moment. The log (or journaling activity) will occur outside of class and will be shared in a subsequent class meeting.
In class, students will exchange their logs, respond and discuss, and then form larger groups which will discuss disparate ways of paying attention to sensory experiences. Students will develop a deeper understanding of their own perceptions and how those perceptions can be recorded and used to evaluate an environmental setting. This activity is qualitative; it requires students to create an informal, subjective journal of their sensory experiences once each hour for a ten-hour time period prior to class.
When students share their individual qualitative experiences in pairs and small groups, they will begin to see patterns emerge that will enable them to develop quantitative observations for future use. They will also begin to relate their sensory experiences to the social, biological, and geophysical aspects of their personal environment; students will begin to explore how these system components are interrelated and how exposure to them may impact human experience and well-being. After the group discussion, students will reflect on the interstices between qualitative and quantitative analysis by way of their sensory logs and mutual discussion.

In this unit, students will develop protocols for the collection of sensory data (scents and/or sounds), plan and execute the field collection of sensory data using developed protocols, analyze collected data, and create a map that communicates findings and impacts on the local population.
The advantage of using sensory data is that students are equipped with the analytical equipment (ears and nose) and are familiar with its use. However, students may not have taken the time to consider the variety of perceptions that occur within a group of people who are sharing a sensory experience and the impact that variation can have when collecting and analyzing data and subsequently communicating the results.
In this unit, as in the entire module, sensory data is considered in two contexts: First, as an indicator of environmental conditions, and, in some instances, environmental disruption. Second, as a proxy for data that is not as easily collected or as readily analyzed such as air or water samples. One of the challenges of developing these protocols will be discerning individual components from a complex system and developing an approach for systematically recording these data. This, though, gives students important exposure to the challenges of understanding and characterizing today's societal problems, which tend to include many interrelated dynamic causes.

In this unit, student groups will evaluate different environmental case studies to critically investigate qualitative and quantitative data analysis, collection, and inquiry. Students will begin to consider different forms of sensory-related data collection and how experiential knowledge informs the ways in which one forms analytical, evaluative questions. Student expert groups are provided one case study (different expert groups will examine at least two different cases) that has a number of different kinds of resources that students will examine (e.g. journalistic, scientific, narrative, visual, auditory). Students will use cooperative learning methods to engage with problem-based inquiry rather than have the case study information delivered via instructor-based lecture. Given that students across disciplinary contexts may not have been exposed to scientific methods of investigation, this unit encourages systems thinking alongside other methods of investigation. As students consider the variety of perceptions that occur within a group of people sharing an environmental experience, students are able to consider the impact that different types of data have on one's perception of data collection and its analysis. This exercise also demonstrates the utility of interdisciplinary thinking -- by examining data sets from multiple academic disciplines, students gain a more complete understanding of the case study compared to what they would have understood by examining data from a single research approach. The activity also provides students with an opportunity to practice interdisciplinary thinking and collaboration skills. The cases address several key environmental challenges: soil contamination, water resources, and the impacts of industrial agriculture.
A collaborative learning method is used in conjunction with guided class and group discussion to critically examine different types of data and encourage consistency of data analysis between student groups. This unit uses a group exploration and presentation activity to ensure equal distribution of materials and accountability among class participants. In essence, the students teach each other about the case studies with the instructor providing questions to elicit depth and synthesis between groups as well as to ensure that critical data analysis is undertaken.

In this unit, student groups will use sensory data (scents and/or sounds) collected in the field to create maps of the sensory environment and relate their findings to larger environmental problems identified in their guiding questions and hypotheses. This unit is designed to build upon prior units in which students develop guiding questions and hypotheses, field data collection protocols, and field investigation plans. The field investigation will require a base map on which to record data and a final map on which to display data and characterize the study area and environmental impact of the mapped data. The base map will be derived from aerial imagery if the investigation site is outside. The base map will be derived from a building schematic or floor map if an interior location is mapped.
Class time will be devoted to developing maps on which students will display the data collected in the field. Students will use Google Earth or other online resources to obtain aerial (or other schematic) imagery of their study area. They may use an aerial image as a base map or they may draw their own maps based on the aerial imagery. If the site is indoors, a blueprint or floor plan can be the base map, or students can draw their own maps based on an existing image or schematic.
Sensory mapping allows students to identify scent plumes as they migrate away from source locations. Odor plumes and sounds are analogous to plumes of contaminants that migrate through groundwater, surface water, and air. In many instances, the presence of unusual odors is an indicator of migrating contaminants and can lead to sampling by environmental professionals (including geoscientists) to confirm and quantify contaminant migration through the environment. These maps serve as representations of the complex odor or sound systems in the students' chosen geographical areas.
