Would you cross post this to amsat-edu at amsat.edu?

Here's the angle. This is exactly the type of graphing project that a
school math class could use to meet STEM standards. Not only is graphing
and plotting part of standards in middle schools and high schools so the
the concept that heavenly bodies have a predictable movement.  I would like
to see the link to your page posted with a challenge to develop lesson
plans around it that meet those standards. I like things that start with
hands on activities that then can be ported out to demonstrate the same
concept with technology. Follow it up with a satellite contact. Hooked!

Thanks for the post.
