Soil Temperature datalogger installed at Norfork Rebels 4-H Club meeting site (ATM-05), 7 Nov 2004
Soil Temperature datalogger installed at Matney Knob (ATM-07), 8 April 2005 following approval of a Special Use Permit from the US Forest Service Office in Mountain View, AR.
Norfork Passive Irrigation Experiment (PIE) Max-Min Digital Thermometer Installed September 2005 (ATM-01) replaced due to defective soil lead on 1 May 2006. HOBO datalogger (ATM-02) installed Feb 2006, HOBO datalogger installed at Tallgrass field site (ATM-03) September 2006. Grazing cattle "ate" 50 cm depth soil temperature sensor lead 12 April 2007. Same fate destroyed all 4 soil moisture sensor leads during installation of Davis Weather station co-located with Tallgrass field site

Early "Easter" spring freeze in 2007 destroyed many species new leaves. Borings of select species made in May 2007 as a baseline for annual ring analysis by next year's students. Anecdotal evidence suggests that such a freeze has not happened here since the 1974 era. For a graph of the freezes diurnal datalogger records of several various local (map) site recordings, select the underlined link.

GLOBE is an educational program that enhances kids learning about their environment using scientific processes, measurements, experiments, and real-life examples from within our community and its locale. The students collect data on the environment and enter it into a global database over the Internet. From it they can access other student's data from around the world and compare it to their own.

Although primarily started as a scientific program, one can readily see opportunities to expand participation into such fields as mathematics and geography. Specific scientific protocols, focused upon the age and abilities of our students, allow them to examine our atmosphere, land cover, soils, hydrology, biology, and botany. The program includes an elementary introduction to Remote Sensing using Landsat satellite data from a photograph of a15x15 kilometer (9x9 mile) area centered on our school. From it students can perform ground-truth validation of pixel data and get a macro scale view of how Norfork fits into the rest of our earth's ecology. The opportunity also exists for high school students to manipulate the computer image of the Landsat data file using multi-spectral software to observe land use changes, the spread of urbanization, and other large-scale, man-made, adaptations of nature.

Teachers from both Norfork Elementary and High School have attended a methodology workshop and have been certified in the GLOBE scientific protocols. A large amount of scientific equipment was presented to the school so that standardized scientific data could be collected by our students. Finally, several sets of scientific software were donated for our student's use.

Suggested modifications to soil thermometer to enhance reliability of measurements, prevent accidental injury, and protect the thermometer from misuse. Drawing measurements may vary according to the thermometer being used.


To allow for an exact drilling of a hole in the center of the mop handle, one might fabricate a drill press jig similar to this if no machinist vice or centering clamp is available.
