Time is a continuous sequence of events taking place.
The main units of time are: seconds, minutes, hours, days, weeks, months, years etc.
Three different ways to measure time are: Water clock, sand clock, and pendulum.
The water and sand clocks were made using plastic cups and the pendulum was made using a small weight tied to a rope.
The water and sand clocks were made using plastic cups and the pendulum was made using a small weight tied to a rope.
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 from another. This was the same for the sand clock.
The water clock measured time by how long it took for the water to reach a mark. The sand clock did the same. The pendulum measured time by how many times is swung.
There are many other ways to measure time, but water clocks, sand clocks and pendulums are good ways to measure time without electricity.
