I have implemented an adaptation of the EET chapter on the Antartica Ozone layer.I used Image J and Excel to measure environmental changes in the surrounding areas fron 1973-1996 using data sets from 1973, 1980,1983 ,1988 ,and 1996. I have downloaded images from 1973,1980,1983,1988,and1996.Students will measure area affected using Image J, then they will learn how to prepare data for use in excel. They will then create a graph using the chart wizard. I will ask them to make an inference based on the data and images and also ask what factors may have contributed to the changes. edcwww.cr.usgs.gov/earthshots/slow/MtStHelens/MtStHelens1973 . I felt the investigation was positive .I received much feedback and many questions and discussion about inferences for the future. Not having access for all to have hands on experience showed a lack of confidence in use of tools. I hope within the next few months to obtain a traveling tech lab to have for use of tools more often.

Brian, how long did it take you to implement this activity, and how many students were in each group on the computers?

Sounds very interesting Brian. I couldn't get the link above to load and I am curious what kind of environmental changes the students focused on. Did they measure change in biosphere, or bodies of water? Did you attempt to have anyone (or yourself) try Image J analyze the amount of geosphere that was displaced after the eruption? I know a few (Brendan comes to mind) of us were looking for ideal images and ways to perhaps estimate volume. I wasn't quite sure of what you meant by "Not having access for all to have hands on experience showed a lack of confidence in use of tools." Was this an issue on sharing computers or did you have to do it as a classroom demonstration?

Hi ,
I had to do as a classroom demo so it really took away from each student's use of the tools. I was able to get partial participation and maximize its potential for the students. In the images we focused on vegetation affected with environmental changes.This is part of two lessons with both Science and I have incorporated it to Social Studies as part of a Climate and Vegetation unit.
