SUNDIAL

product description

HOW IT WORKS?

Look at the shadow projected by the wooden pole. If the sun is not covered by clouds, read the hour shown by the shadow. At noon, sun rays indicate the shortest shadow line and indicate the North. Compare readings with time shown by your watch.

DID YOU KNOW…?

Since Copernic’s times we know that Earth rotates around it axis and performs one such rotation per day. Differences in reading on various clocks results from the fact that sundial shows real, local sun time, which is different for each town. Local time also depends on geographical length. We use conventional zone time due to practical reasons. The Europe (from Lisbon to our eastern border) is covered by one time zone and everywhere in it is valid the same central European time, which precisely corresponds to local astronomical time at geographical length of 15° E.

HOW IT INFLUENCES CHILD’S DEVELOPMENT?

Using a sundial in Experience Park teaches kids how to perceive various relations between geographical directions, the Sun, and time existing in the world. Playing with a sundial is a great way to develop observation and analysis skills, as well as perfect opportunity to break away from daily life saturated with electronics.
