From our own planet Earth to galaxies far, far away, the STAR LAWS series brings the whole universe into focus and makes astronomy clear, engaging, and fun!
The word astronomy comes from the Greek words astron which means star and the word nomos which means “law”. Astron nomy therefore translates literally as STAR LAWS. Astronomy is the study of the laws of nature that govern how stars and other bodies in space appear to move across the sky, how they form, and how they change over time.

All of our videos come with worksheets. Just visit each individual page to download them.
