This assignment has been used with a 9th grade integrated science class. The students in here are mostly lower level and special needs. I use it as a culminating activity after doing an overview of the 6 kingdoms at the conclusion of my classification unit.
I have done a very similar project with my 7th graders when I taught them and it worked out very well.
You may need to edit the font to make it work out because when it generated the thumbnails it looks like it is a little off.
