About Time: A First Look at Time and Clocks

Time to read a book.<br>Time to wash dishes.<br>Time to do this or that.<br><br>You say things like this every day, all the time. But there was a time when time itself was undefined - no one knew the difference between a minute, an hour, or a day.<br>Then people started creating tools to measure time. First they used the big stuff around them - the sun, the moon, water. Soon after, using the knowledge they got from their natural time-telling tools, people began to build clocks - huge clocks unlike the ones we use today. They also used their knowledge of the sun and moon to create calendars made up of months and years.<br>Now, centuries later, we have clocks all around us. We can easily figure out how long a month is. But it took many years of tinkering and inventing to perfect the art of telling time. You could take a few moments now to read all about time. If you have a minute, that is.
