Time | Maths

Time tells when something happens.

There are many different ways of measuring time. They're: seconds, minutes, hours, days, weeks, months, years, decades and ect. The ones we investigated were water clocks, sand clocks, and pendulums.

The water and sand clocks were made using plastic cups and the pendulum was made using a weight tied to the end of a rope.

With the water clock, a little hole was drilled at the bottom of a plastic cup and there were marks which indicated how long it would take to get to one mark from another. The same process was used on the sand clock.

The water and sand clock measured time by how long it took for the water and sand to reach a mark. The pendulum measured time by how many times it swung. The pendulum was actually very accurate.
