Assess Grade 3–5 students' understanding of how aerobic, strength, and flexibility activities support children's physical health and energy. The quiz will test clear definitions and age-appropriate examples of each activity type; short- and long-term benefits (cardiovascular fitness, muscle development, flexibility, posture, energy and mood, injury prevention); principles for combining activities into balanced, safe sessions and simple progressions; and application to short scenarios where students choose appropriate activities and safety measures. Items target comprehension and basic analysis for classroom use.
