Shows for Schools

We offer the excitement and wonder of a 'Big Sky Dome' not just a wide screen display, or temporary structure.

Sitting inside our 11 metre dome you fully experience the dynamics of the heavens making comprehension and learning easy.

The effective teaching of astronomy involves viewing the night sky, but to take students "star-gazing" is often impractical for many reasons. A Planetarium brings the night sky to the students. It makes clear many of the basic aspects of astronomy and space science in an exciting and effective way.
