Our free resources are units that are typically used for a one-hour presentation (sometimes more) on a specific topic in Astronomy. We developed these resources for our own Astronomy classes at High School or for our night classes. They are in the same format as our Ebooks and only require an internet browser with the Adobe Flash add-on. Apart from general presentations and classroom teaching, these units are ideally suited for self study as well.
We gladly make these now available without any cost. Once published here, they are public domain. Read our Site License Tems & Conditions. They can be run directly from this website or you can download a zipped version for installation on your own computer(s) or network server. The download will require you to register as a client in our on-line store, but there are no costs or any other strings attached.
We are presently revising several resources and these will soon be available. Join our mailing list if you want to receive automatic notification of new releases, or alternatively check our News Desk frequently.
