Time

Time identifies when something happens.

There are many different units of measuring time. They are: seconds, minutes, hours, days, weeks, months, years, decades and ect.

If people want to measure time, the object they are measuring time with has to be consistant. Making a hole at the bottom of a plastic cup, putting water or sand inside of it and then letting the water or sand flow out is another mechansm for measuring time.

There are many other mechanisms that measure time but these are only some of them.
