I recently came across 4H in the excellent movie
Leave No Trace (2018)https://www.imdb.com/title/tt3892172/
The basic premise is this Iraq/Afghan veteran father is raising his daughter homeless in the woods outside Portland, Oregan. He struggles with PTSD but clearly still takes care of his daughter, including teaching her english/math (which the social worker later says is beyond her typical grade level) and of course outdoor survival skills.
They eventually get caught by city workers/police and they end up housed via a sympathetic farmer where he gets a job and his daughters ends up finding a 4H social program for kids. She gets exposed to socialization programs, in particular a local group raising/training rabbits for competitions.

The biggest issue with the child in the film wasn't her lack of education, but her lack of socialization. And the (brief) 4H scene was a great demonstration of the value of these sorts of programs for kids.
The failures of the US public education system on grades and the (alleged) solutions has been talked to death in the media but these sorts of social boosting programs deserve their own hype.
It's particularly interesting that it spawned out of the agricultural agencies, not your typical urban ones.
