This Science On a Sphere script was written as a program for young (early primary school) students. The program gets students moving, talking, thinking and participating in the sphere experience while learning about space and interplanetary science. It is connected to a book called G is for Galaxy, which can be read aloud to the students in class before or after the field trip to SOS, and PowerPoint slides, which can be shown on auxiliary projectors in conjunction with the presentation playlist shown on SOS.
