Aussie children stunned by 'object from outer space' at their school

A ‘meteorite’ crash-landed at a Sydney junior school in a staged demonstration to launch National Science Week that left students stunned.

Staff and students arrived at St Pius X College last Monday where they discovered the replica extraterrestrial rock outside the primary school in Chatswood.

'It’s not every day students arrive at school to find space debris waiting for them, and the discovery quickly became the talk of the college,' the school wrote on its website.

Experts from GeoScience Australia and a Willoughby Fire and Rescue crew attended the school where they fielded questions from amazed students.

While the school has since confirmed the episode was simply a demonstration to mark the beginning of Science Week, the excitement felt by students was genuine.
