On TV in the Netherlands we have a program that aims to educate the public (state sponsored tv), every couple of months there is a new episode, they are listed here (but they are in Dutch): http://dewerelddraaitdoor.vara.nl/DWDD-University.2772.0.htm...
So far they were about the big bang, the quantum world, Einstein (All from Robbert Dijkgraaf, now director of the Institute for Advanced Study in Princeton), The cow and silicon valley. They were always set in a large theater (with live public) with a stage full of props (Inflating balloons to represent the inflating universe, buckets of sand to represent the amount of stars in a galaxy, cameras on rails to represent relativity, living cows as well as all their nice parts of meat on display.) These "presentations" are very nice to watch and my wife who is not a scientist always enjoys them as well.
There are also museums like Nemo in Amsterdam (https://www.e-nemo.nl/nl/ontdek/brein/) and Naturalis in Leiden (http://www.naturalis.nl/en/), these places are filled with rooms with stuff to touch and experiments to perform. I'm sure the US is laced with those as well so it is not that ground-breaking of an idea.
A holo-deck would be the killer feature for this way of communicating.
