Physical Education (PE) is a class or program that focuses on teaching students about physical activity, exercise, and healthy habits. The primary goal of PE is to help students develop the skills, knowledge, and attitudes they need to lead a physically active and healthy lifestyle. This can involve learning about anatomy and physiology, sports, games, physical fitness, nutrition, and health. PE classes are typically taught by a trained physical education teacher and may involve a mix of lectures, hands-on activities, and physical activity. The frequency and duration of PE classes vary by school and grade level, but they typically take place once or twice a week for 30-60 minutes.
