Assess educators' ability to analyze how light exposure (full sun vs. shade), watering levels (under-, optimal-, over-watered), and soil types (sandy, loamy, clay) each independently and interactively affect seedling growth in a classroom garden. Items test designing simple controlled observations appropriate for Pre-K–Grade 2, identifying variables and confounders, interpreting small-sample height/leaf/count data and child-made records, and making evidence-based recommendations for teaching and plant care.
