I use this report outline for multiple grade levels and varying abilities. For my Honors level students, this is an outline for making an essay or presentation. For my lower level students, the outline is the assignment and I may have them present it informally.
Since it is absolutely editable, feel free to change wording as needed. I usually provide a list of Biomes on the board but you could even change 'Biomes' to 'Ecosystem' or 'Habitats' to make it more flexible.
