Be a Gnomon!

You don't need anything to tell what the solar time is. Your body is all you need. In this activity you will be the gnomon; your shadow will indicate the solar time.
Este módulo te permite ser tu propio Gnomon y marcar la hora con tu sombra

Don't worry if your shadow does not reach the numbers of the sun dial; you can extend the shadow line by holding your arm above your head. On this type of horizontal clock, the hours are marked on a large ellipse, whose major axis is oriented in the East-West direction. The plaque situated in the centre on the minor axis of the ellipse shows the months of the year.


To make a correct reading, you need to stand on today's date and your shadow will indicate the time. Stand on the central plaque and look for today's date. What time does your shadow indicate?
