Class of kids experience and learn outside of the classroom. learning resources are quickly accessed wirelessly

The environment could be like a botanical garden, or an industrial hydroponics plant.
Either way adult workers can be shown doing the sorts of jobs the kids are learning about; interactions, teaching/showing them various skills.
 

Could include some small robots/drones. These could be used for all sorts of tasks and run on a very powerful general AI. This AI would have to run externally so the drones rely on low latency 5g internet to receive that information.
