Re: planetary orbits

I have an activity I just finished with my astronomy class that uses max.
elongations of Mercury to plot its orbit. It's in Word format, with not too
many directions, but probably enough for you to figure it out. If you'd
like, I can email you the file.

Subject: planetary orbits


I am teaching astronomy for the first time this year (high school) and
recall seeing an activity in the past where the student would plot the orbit
of (mars? mercury?) based on the dates of greatest elongation or opposition.
It was a "kepler's first law" activity. I have searched the internet to no
avail. Is anyone else familiar with what I am talking about. Any
assistance is appreciated.
