  1. Analyzing digital images for classroom environmental research Mort Sternheim June, 2012

  2. The Big Idea • Digital cameras and computers are widely available for students and teachers. However, they are mainly used for documentation: creating PPT presentations, handouts, posters, etc. • STEM DIGITAL shows how digital image analysis can be applied to environmental (and other) research in STEM courses • Application to studies of air quality, water quality, arsenic contamination • Other examples from climate change, diffusion …

  3. Analyzing Digital Images Software • Software package developed by John Pickle, Concord Academy (formerly at the Museum of Science, Boston) • Updated by Dan Gullage, STEM Ed • Free, student friendly, for Windows and Mac • Spatial, spectral (color), intensity, temporal analysis tools • You do not have to master all of ADI to do simple tasks • You do nothave to have a computer lab • Color and digital image basics programs • Downloads: www.umassk12.net/adi

  4. Monday –Geometry, Intensity • Applications that don’t need deep under-standing of basics • Lengths, areas, angles • Intensity – albedo • Diffusion - CO2 experiment with BTB • Brainstorm geometry, intensity • Begin water quality week-long experiment

  5. Tuesday – Basics Adding lights Adding pigments

  6. Pixel = Picture Element 15 x 16 512 x 512

  7. Tuesday – Color Applications • Aiptasia • Coral reef model • Air Quality • Making ozone strips • CO2 air experiments • Brainstorm color • Water lab tour • BBQ

  8. Wednesday – Ozone, Time • Ozone measurements • Another color application • Time • Movie Tracker software – falling ball • Time lapse – oscillating chemical reaction

  9. Thursday • Arsenic • in water • in rice • in pressure treated wood • Remediation • Lab tour • More brainstorming / planning

  10. Friday • Explore water treatment options • Analyze water quality data • Evaluation focus groups • Careers • Cleanup

  11. Example – studying eye color • I was sort of surprised at how quickly they learned to use it… Once I showed them the size of the rectangles I wanted for sampling colors, they just took off. • The most interesting thing we discovered was that blue eyes are not blue! • Sharon Cumiskey, 8th grade, Plymouth, MA

  12. More examples • Used the ADI software to measure the grain size of known rock thin sections to identify the mineral composition. • WOW it really worked and my five 8th grade accelerated Regents Earth Science classes had so much fun using it. • Ray Szczerba, Clifton Park, NY • Wind Turbine Lesson  • The Movie Tracker software, worked out well. Students were able to determine the revolutions per minute of their blades. I used this data as the determination for how well their turbine ‘functioned’. • I will definitely continue with this analytical tool for the turbine project next year! • John Nicholson, Freeport ME Middle School

  13. Academic Year Program • Collaborative projects via Moodle • Teacher with class, or after school group, or alone • Air quality, arsenic, water quality in fall • To be decided in spring • 3 reduced cost credits available for summer, 3 more for academic year; otherwise, PDP’s • Short option: one class project reported on Moodle, 3 summer credits available; otherwise, PDP’s

  14. What We Provide • Kit with key materials for air quality, arsenic, water quality collaborative projects • $200 budget for classroom materials • Stipend $375 summer; $300 more for full academic year program ($675 total) • Support via Moodle, email • More details later…
