Students use a simple model of the Earth and Sun as seen from
space to explore the sun's apparent movement across the sky over
the course of a day and year. They consider the apparent direction
of movement and changes in the sun's angle.
Plan the first part of this investigation for a sunny, dry day.
If possible, launch it in the fall.
Invite students to imagine they are far out in space and can see
the Earth and our sun. Ask, What would you expect to see happening
and why? Make four different drawings, to show what you'd see
during a day or year. Once students have completed this,
ask, What questions do you have? Save these for students
to revisit during and after this activity.
