Candle to Quartz clock

When Mrs McLeod comes into the classroom for the day we start off by learning about Clocks and Time measurement or something.We have been learning about Way back when clocks weren't invented they used to use the sun the moon and the stars as clocks .So when the sun came up the people would get up and when the sun went down and the Moon came up they would go to bed so they could have gone to bed at six o'clock if they wanted to that's a little strange (:
