Introduction NorthWest Arkansas Community College has a nature area that is currently being restored. Students from Environmental Geology, Plant Biology and Intro to GIS classes, are working together as a learning community to promote the restoration and maintenance of the area as a Learning Laboratory.
Overview The Living Laboratory area is outlined in red and includes a prairie, mima mounds, spring fed pond, post oak forested areas and walking trail. The NWACC community is working to reclaim, restore and maintain this area for study. Walking Trail Post Oak Forest Mima Mounds Spring Fed Pond Prairie
A Learning Community… Students from Environmental Geology and Plant Biology collected data in the Learning Laboratory area and contributed to a GIS database that was used by the Intro to GIS class. The Intro to GIS class was able to generate an interactive map of the NWACC Living Laboratory. The map will serve as a valuable resource for land use planning committees and for the scientific learning community, both at the college and public school levels.
Plant Biology Restore Native Prairie in the Living Laboratory. Provide GPS Points of Areas being worked in. Provide Area Biota. To use the map to monitor native plants that are being reintroduced as part of the Restoration of the Prairie. Intro to GIS Generate an interactive map for future use in the NWACC Living Laboratory observation. Use provided points given by the Plant Biology and Environmental Geology classes. Class Goals
Environmental Geology Continue to collect data in the Living Laboratory to assess possible impacts of human interaction in the area. Collect GPS points throughout the Living Laboratory Provide a simple soil analysis of the GPS points. Class of Fall 2008
What did we do? Take GPS points of specific spots in the NWACC Living Laboratory. Take Soil samples of those specific spots. Do a simple analysis on color and content of acquired soil samples.
Collecting Data We took points based on the South side of the living laboratory. This information can be categorized into subunits. Pond Mima mounds Planter boxes
Materials and Procedures The materials used to collect the samples are:, Trowels, Hammers, Tubes, Cellophane, and Sample Bags. The trowels are used to collect the sample, or to remove some of the debris such as, rocks, leaves, straw, and trash from the surface before collecting the sample.
Procedures Continued I The tubes are used to bore into the soil to collect the samples, but when the tube hits a rock, the hammer is used to drive the tube all the way into the Ground.
Procedures continued II The cellophane is used to help the soil preserve its shape as well as preserve the nutrients and some of the moisture. The bags are used to hold the sample for future use.
Analyzing the Soil To analyze the soil we used the methods in a “Soil Classification Chart.” PROCESS: First we placed about two teaspoons of the soil, from different parts of the sample, top, middle bottom, in our hands and added small amounts of water until it felt like a moist putty. After this we went through the chart and determined if the soil samples were sand, loamy sand, sandy loam, silty loam, loam, sandy clay, silty clay, or clay. During the study we used techniques such as squeezing the soil into balls, making ribbons, pinching, rubbing, all while using our senses to determine if the soil was gritty, smooth or both.
What we found… Area Elevation Range from 1301 feet -1324 feet above sea level Soil types obtained Pond area Silty loam, slight sand Mima Mounds Range from loam to silty clay loam Around planter boxes Silty loam, slight sand
How Can this information be utilized? In the future, this information can be used to decide what organisms will flourish in this area. The learning community can utilize and add to the information for future purposes as well.
Skills Developed We learned to work as a team. We learned how to use GPS units and collect geospatial data for map building. We learned how to be self directed in our learning. We learned to be organized and to communicate within the framework of a team. We learned about the global aspects of environmental geology. We learned interdependence within a group and as a member of a global learning community.
