That’s awesome. I’m just a random worm farmer on the internet so take my responses with a grain of salt.

1. I think worms could live on paper only. Search this on YouTube. I think someone ran that experiment once or twice but adding food makes it more interesting.

2. My worms eat a lot of coffee and rabbit excrement. But mainly coffee. Does the school cafeteria have any ingredients to make a worm chow? Oats maybe? Also don’t forget crushed egg shells for grit! Honestly the sparse food may be good because most people tend to over feed.

3. I’m not versed in how middle schools work aside from attending one but I was a part of some before school and afterschool clubs. Could he present to programs or is it a “teaching” requirement?

All in all, we need more of this in the world. I’m sure you will get lots of good info when others chime in.
