Children walk through a world of wonder. They discover reflections in shiny holiday ornaments outside nearby stores and giggle as their images distort in the curved mirror (this leads to a great talk about foreshortening).
They ask about the "life span" of a shadow and whether they stay put or move before disappearing at night.
Could I have given a more poetic description? Nope.
Leave it to children to find the wonder inherent in ordinary things! I'll say it again, "I have the best job in the world!"
