S undials

Sundials

By Chloe Williamson


Looks like

Looks like

  • It looks like a small table with a stick (called the gnomon) coming out of the top, tilted at an angle.

  • Can be made of metal, stone or sometimes glass.

  • Sundials have a pattern on the table to tell the time.

How does it work

How does it work?

  • Sundials show the time by where the shadow of the gnomon is on the sundial.

  • As the sun moves across the sky the shadow of the gnomon moves across the face of the sundial and shows the time on the pattern.

  • The pattern works like a face of a clock.

Where can they be

Where can they be?

  • Sundials can be placed anywhere as long as there is direct sunlight.

  • Sundials in the northern hemisphere have to point the gnomon exactly north while in the southern hemisphere it has to point exactly south.

  • Some sundials can also be portable, meaning they can be moved around.

Sundial facts

Sundial facts

  • Clock towers used to be checked that they were showing the right time by using a sundial.

  • In the olden days we had sundials but now we have clocks and watches which are much more portable and accurate.

  • The first sundial was made 5500 years ago.
