Final answer:
Students can participate in various community service activities like volunteering at food banks, animal shelters, nursing homes, or community gardens.
Step-by-step explanation:
When the high school decides to add a community service hour volunteer requirement, the students can decide to participate in various activities that aim to help the community. For example, they can volunteer at local organizations such as food banks, animal shelters, nursing homes, or community gardens. By participating in these activities, students not only fulfil their community service requirement but also develop empathy, teamwork, and a sense of social responsibility.
