I posted a set of photos of Activity 2.2 finding the slope of volcanoes. If
you have the patience to wait for the upload two of the photos towards the
bottom shows my kids using the 8 bit camera and the results. The neat part
about this activity was we went directly from taking the photo to measuring
the angle using the NIH software. When the kids did their own crude
measurements using the protractors the answers had a spread of ten to 15
degrees. Using the software the slope of all of the "Cinder Cones" was
within 2. I thought that was really impressive! Any questions? Feel free .
. .  Have a great holiday.
