The school had organised for the Australian Academy and Research Network's Immersive Global Learning Environment's portable device, known as IGLEw, to be at the school from Canberra, and open to the public.

The IGLEw is an inflatable immersive 3D theatre that helps explain how the  solar system and the universe  work.

It even shows constellations, galaxies, planets  and moons in real time.

Grammar head of house and science teacher Patrick Moroney said the device was a great way to get people to learn about science firsthand.

``Kids are the scientists of the future and anything you've got that gives them the opportunity to do something that excites them  is great,'' he said.

Participants were even able to control the device themselves to see how the system worked.

Highlights included seeing how many satellites circled Earth and how many galaxies are believed to exist.

The IGLEw will be transported  this week to Hobart, where it will be used by a number of schools.
