The diorama simulates the tracks across the sky of the Sun at summer solstice
(longest track), winter solstice (shortest track), and the spring and fall
equinoxes (medium track). A bead simulutes the Sun moving from rising along
eastern horizon to setting on wester. The bead can be moved from track to
track to explain the solstices and equinoxes.
My program was a guided walk through the park and the topic was
the
winter solstice. ...
I copied a diorama used by Dr. and Mrs. Scherrer during
the training that demonstrated the sun's position in the sky at
different times of the year. This became my most effective
teaching
tool. Everyone loved the diorama!" Cidney Webster, National
