Concept Map

Organise the vocabulary, quantities and relationships into a connected model.

This extension applies that lens specifically to Day and Night.

Earth is always slowly spinning, like a top. It makes one full spin about every 24 hours — and that one spin gives us one day and one night.

The Sun can only light up the half of Earth facing towards it. On the side facing the Sun it is day; on the side turned away it is night. As Earth keeps spinning, your part of the world turns towards the Sun (sunrise), then later turns away again (sunset).

Worked example. When it is daytime here in South Africa, it is night-time on the opposite side of the Earth. Both places share the very same Sun — they are just facing different ways as the Earth slowly spins.
