These activities are designed to complement academic learning and promote social interaction, personal development, and community involvement. High school activities can include sports teams, clubs, music and arts programs, student government, volunteer services, academic competitions, and various special events such as dances and fundraisers. Participation in these activities allows students to explore interests, develop skills, foster friendships, and enhance their college applications, while also contributing to a sense of school spirit and community.
