I am going to use the Animal Hands lesson from the Center for Image Processing in Education as a model for my lesson. The students will use ImageJ to examine x-rays of ten different animal hands. They will compare/contrast the structures and predict the main function and the "owner" of each structure. I still have to work on adapting the lesson plan for use with my students. The lesson wasn't written for ImageJ so changes will have to be made. I also want to re-write the student hand-outs to emphasize certain concepts related to evolution and homologous structures.

Christine,
I would like to use something like this for my unit on evolution. I am not sure how to use Image J to make the comparisons. It sounds like your lesson is great for structure and function.

Mary,

I plan to change some of the questions in the original lesson plan so that the activity focuses more on evolution, mainly on how scientists use homologous structures as evidence for evolution and to create evolutionary trees. In ImageJ we will use some of the more simple functions, such as zooming in/out and enhanding brightness/contrast.

Carla sent me a link to the Animal Hands lesson rewritten for ImageJ, just in case anybody else is interested.
