Research labs are much less densely packed, and in-person interaction is less. In less affected states lab-based research is starting again.
For high school level, sure.
But I can't see a sane way to let students handle acids like I did in chemistry labs during college, and physics labs have equipment that is too complex/expensive/dangerous to send to the students.
There’s an entire community of autodidacts that do this sort of thing at home as a hobby. They have lots of advice on PPE, materials handling, storage, where to find papers and books etc. Some of them even record experiments instead of just writing them down so everyone can watch.
This does mean that students from out of city will have to find safe accommodation, but thankfully they are only a small part (<10%) of the student population at my uni .
