Finding Volunteers/Chapter Leaders for High School Service Organization

Hi! I’m a junior in high school who started a service organization a bit over a year ago. Our projects largely focus on improving STEM educational opportunities for students, designing STEM curriculum, creating social and emotional learning videos, hosting virtual STEM events/mentoring, and other outreach. For a while now, we have been expanding and creating new chapters, which works well since most of our volunteer work is virtual.

However, we are currently facing an issue: we have lots of service projects waiting to be done to improve educational opportunities for students (and great nonprofit organizations who serve as our partners), but we are having trouble finding students to volunteer and/or start and lead new chapters. This is largely because I attend a very small high school, and school being online does not help either.

So, my question is do any of you have suggestions for finding other like-minded high school volunteers/chapter leaders for such an organization, especially through the internet or other means? Thank you so much for your help!
