The sky above us

The rotation of the Earth is investigated by observing the length of a toy figure’s shadow in the course of a day.

As an extended task, you can use the Stellarium software to investigate the movements of the Sun. Alternatively, the students can make real observations of the position of the Sun in the sky in the course of a year (the analemma pattern).
