A sundial is a tool that uses the sun to help tell the time. It consists of two main components - the flat plate and the gnomon. When the sun shines onto a sundial the gnomon (the part that sticks up) casts a shadow. This shadow will fall somewhere on the flat plate and using the numbers on the flat plate, we can tell the time.

We loved collaborating with 9Ay and look forward to sharing more learning with them.
