This includes a handout with the requirements for an Environmental Issues Poster. This poster can be completed at the middle school level and can be scaled to the high school level. The students are allowed to choose an environmental issue listed (or come up with their own).
It also includes a sheet that can be used as a rubric, which allows plenty of space to write notes of individual students' projects. I also included a "Voting Sheet" where I had the students review the posters in a gallery walk, and voted for various awards for each poster.
