  1. Sundials By Chloe Williamson

  2. 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. http://www.liverpoolmuseums.org.uk/kids/games-quizzes/sun/san5.html http://www.kidsgeo.com/geography-for-kids/0022-sundials.php

  3. 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. http://www.liverpoolmuseums.org.uk/kids/games-quizzes/sun/san5.html

  4. 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. http://en.wikipedia.org/wiki/Sundial http://www.kidsgeo.com/geography-for-kids/0022-sundials.php

  5. 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. http://www.liverpoolmuseums.org.uk/kids/games-quizzes/sun/san5.html http://www.kidsgeo.com/geography-for-kids/0022-sundials.php
