This resource includes an ecosystem model project rubric, as well as cards that can be used to assign different ecosystems if desired. Included is a research worksheet the students complete to prepare for their model. For my class, I had them include all questions in their model (e.g., if pollution was an issue their ecosystem faced, they included trash in their model), but that is subject to teacher discretion! I used this in my wildlife management class, but it can be used in different science
