Query: HOW TO (DIS-)ASSEMBLE A PLANETARY SYSTEM (by turning a video game into
  an educational game)   Nowadays, computer simulations have reached amazing graphic results,
providing awesome visual descriptions explaining the evolution of very complex
physics phenomena, implementing the laws of Nature. Sometimes, without a
scientific guide, it is difficult to distinguish between simulation and
reality, but the usage of advanced and spectacular animations is a powerful way
to convey both accurate scientific information and passion for science.
According to this, we decided to develop an innovative scientific workshop
based on an unconventional instrument: a video game. We used a commercial
software called Universe Sandbox, a physics- based space simulator where
astrophysics objects can be created, manipulated and followed in their
evolution. We prepared a set of dynamic scenes to take the public through a
virtual space journey whose main topics were planetary formation, orbits,
habitable zones, types of stars, stellar explosions, and asteroid collisions.
The interaction with the audience was at the heart of the experience: every
question, suggestion, or idea was inserted in the simulation in real-time. This
workshop was first proposed to the national festival of science in the city of
Bergamo, in Italy, and we report our experience in this contribution. This
activity is very easy to be replicated everywhere, both online and in-presence.
