Time

Time is when an event is happening.

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

The three ways to measure time are: sand clock, water clock, and pendulum clock.

With the water clock, a hole was drilled in the bottom of a plastic cup and there were lines which were used to measure how long it would take to get to one mark to the another. The same progress was taken from the sand clock. 

The water clock measured the time by how long it took for the water to reach each mark. The same progress was taken from the sand clock. 

The pendulum was measured time by how many times is swung.

There are other ways to measure time, but the three main ways are good methods to measure time without electricity.
