Jim, You describe in detail how school children can learn by experience about the relationship between shadow and time in a day. This is a challenging task. At the end of the day the children have a notion of a sundial for that day.
How do you learn by experience that the point x (the position on the north-south line) changes through the seasons and so how they learn by experience about the "calendar" of the analemmatic sundial?
