Purpose: Help students understand the phenomenon called nitrogen saturation.
Teaching Approach: "support a statement"
Cognitive Skills: (see
Bloom's Taxonomy) — comprehension, interpretation, evaluation
Student Assessment: justification essay

south-facing slopes in a West Virginia forest. Bars are 1 standard error. Dotted line indicates no stimulation by fertilization. W.
