Sky Journey is a science game about the sky for primary school, grades 1 to 6. The child drags the sun along its arc and the sky colour, the stars and the shadows of the house and tree change with it — for example, "It is bedtime, move the sun". Other rounds ask the child to pick the right sky or moon shape, or to put cards in order.
