Assess Grade 3–5 students' understanding of how aerobic, strength, and flexibility activities support heart health, build and maintain muscles, and protect joints. Items include identifying age-appropriate examples of each activity type, describing basic physiological benefits (e.g., increased heart rate and endurance, stronger muscles, improved joint range of motion), matching activities to outcomes, and explaining why a balanced weekly plan reduces injury risk and improves overall movement; moderate analysis and short explanations required.
