School is going to be a very challenging one. You have a bunch of kids spending around 8 hours together in a closed building and often interacting closely and touching the same objects. I guess it's not any different than an office, but I think it's still worse as kids tend to be germ magnets to begin with and interactions will be closer than in an office.
I can't see them reopening the schools in September, even here, but at same time, keeping kids at home can only go on for so long as it will really start to affect their mental health. I think as adults we can handle isolation a bit better, but kids have a harder time with that.
I think the plan here is a modified reopening, where they have smaller classes, and less people on the buses, and staggered entry, and school every second or couple days so they can split in groups. Or something along those lines. But it's going to be very hard on everyone to manage that. They will also have trouble finding enough bus drivers. Lot of bus drivers are retired people who just want a little something to do and a bit of extra money, but it will end up being a full time job having to constantly disinfect etc and doing way more pickups.
