Go outside on a sunny day and look at your shadow! Early in the morning and late in the afternoon, it is long. At lunchtime, it is very short.
This is because the Earth moves around the sun and the sun is in a difference place in the sky at difference times of the day. Sundials use shadows to tell the time. They are the oldest way to tell the time.
<em>Выйдите на улицу в солнечный день и посмотрите на свою тень! Рано утром и поздно днём она длинная. В обед очень короткая.</em>
<em>Это потому, что Земля двигается вокруг солнца, то есть солнце в разное время находится в разном месте. Солнечные часы — это тени, по которым узнают время. Это самый древний способ узнавания времени.</em>
