- The Planetarium is a multifaceted organisation dedicated to astronomy education for all levels, from nursery through to retirement age. It is the Planetarium's unique ability to adapt to changing audience needs that have enabled it to stay at the forefront of science education since its formation. Armagh Planetarium offers a curriculum-broadening experience for school visitors, and our educational programme has been redesigned to dovetail with the new curriculum, while retaining characteristics which are central to an understanding of basic astronomy. Our aim is to demonstrate to our visitors the amazing objects that exist in the cosmos, but to do it in such a way that they do not see our efforts as formal teaching. We call this “Learning by Stealth”. When they are prompted to ask questions, they are engaging in the learning process. All of our school theatre shows are interactive, so that presenters and pupils take an active part in the show. Follow up tasks back in the classroom are facilitated by downloadable PDFs and astronomical factsheets for teachers to use as supplementary teaching material.
