The lesson on natural geography starts in class 3. This is the time students begin exploring the facts about this universe. Natural geography is only perceivable once children witness the movement of the planets. Like science lessons are incomplete without vast exposure to experiments. Once they notice how the magnetic field of the Sun attracts other planets and make them revolve around the Sun, a clear concept about the cosmos builds. Most of the time, the price of the planetarium tickets differs from show to show. 

Nowadays, some educational institutions are arranging for portable planetariums. Here, children get special comfort from their familiar audience and thorough teacher guidance. The shows are also specially designed considering their lesson plans.
