Which functions are interested for children’s and students?
First the beautiful pictures from hobby astronomers are interesting for children. In simulation module exists under menu „specials“ a slide-show, which can show all pictures.
Older children’s or teenagers can maybe interested for diagrams, if diagram shows no difficult things (for example the diagrams under statistic menu or the diagram under “specials” with orbit of planets). It's also a good thing to use the calculator module for convert one distance into a distance with other unit (for example 1 AU into km). Because of comparing with the time the light to takes to travel, a space shuttle flight time and other things, it helps for a better imaging of the great distance in our universe.
