My students complete a Biome in a Box project at the end of our unit. They are expected to include organisms that would create a balanced energy pyramid. I really encourage students to get creative and make their project look realistic. One section of the rubric includes a writing portion for students to explain their connections.This is the rubric I created for students to use as they complete the project. I also included a place at the bottom to calculate the grade. I have a simpler project rubric available in my store.
