This product goes along with my other TpT product: NGSS MS-LS 2-2 Standard Breakdown & Rubric.
This is a Standards Based Assessment that includes a comprehensive scoring rubric.
The assessment requires students to explain and visually represent Symbiosis, Predation, and Competition. In addition, students must explain the relationship between abiotic (non-living) and biotic (living) factors in an ecosystem.
This assessment is very clear and user friendly. No more questioning what grade students earn because the rubric is very straight-forward with no gray area or wiggle room. In order to differentiate, students can be scored using a sliding rubric scale.
My students have done very well with this assessment model and they enjoy being able to draw as well as explain the concepts.
