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
introduction, the pupils can spin around themselves like the
planet Earth to reveal the daily motion of our planet, and they
can try to create different kinds of shadows with a torch.

As an extended task, you can use the free Stellarium software to
investigate how the Sun seems to move across the sky in the
course of a day and how this movement changes in the course of
a year.
