Assess educators' ability to analyze how variations in sleep duration/quality, nutrient intake, and daily physical activity interact to influence Grade 3–5 students' energy, mood, attention, and physical performance. Tasks include interpreting brief case scenarios and simple datasets (sleep logs, activity minutes, snack composition), identifying causal links and confounders, evaluating trade-offs, and proposing evidence-based classroom or home adjustments tailored to developmental needs (ages 8–11).
