Comment on their location in the sky (constellation, relative altitude over the horizon, etc) and track their movement above the course of the next couple of weeks, every day commenting on how they've changed relative to every other and to the background stars (how many degrees, and in what direction, does the moon roatate in one day, for example.  Is this consistent with its monthly (30 day) cycle and is it close to the ecliptic)?  In your way, be as thorough as possible.
