Try this: Make a Shadow Clock
Do this with an adult
With an adult, push a stick into a pot of soil. Keep the pot in a sunny spot. Every hour, place a pebble at the tip of the stick's shadow. Watch the shadow move and change its length! Never look straight at the Sun. Look only at the shadow.

A sundial tells the time using a shadow cast by the Sun. At Jantar Mantar in Jaipur stands the world's largest stone sundial. It is about 27 metres tall, as high as a nine-storey building! King Sawai Jai Singh II built Jantar Mantar. It was finished in 1734. Today, it is a UNESCO World Heritage Site.
