World Around Us Challenge

18th May 2020

This week we are learning about sundials.

 

Sundials are an ancient way of telling the time that also uses the weather.

They use shadows created by the sun. There is a stick or other object which stands in the centre to cast the shadow. It is called the gnomon. (You say no mon!)

As the shadow moves around the circle it points to the hour and that is how you tell the time.

 

Have a look at this presentation to find out more facts:

Here are pictures of sundials from all around the world: Can you find the one in Ireland?

You can make your own sundial and recap some of these facts by watching this video:

Don’t forget to take a photo of your finished sundial if you can.

We would love to see it!
