Native Apps

Executables for Windows and Macintosh computers are available for all of our older projects (NAAP, ClassAction, & Ranking Tasks). The appropriate package for your (or your student's) computer system must be downloaded and installed locally. Note that these are actual applications that run in your native OS and their longevity depends only upon your OS. There is no similar viable solution for Chromebooks.

Note that every simulation in the Astronomy Simulations List is contained in either the ClassAction or NAAP Labs apps. (In ClassAction look under the Animations tab.)
