Duration of time is also measured using sand clocks. Make your own sand clock (timer), in the presence of an adult.

Materials required:

(i) Two waste transparent or glass bottles of small size with caps.

(ii) Strong glue to join bottle caps.

Process:

Join the tops of the bottle caps with each other using a strong glue.

Make a small hole with a fine needle at the centre of the joined caps.

Fill one of the bottles half way with fine sand and close the bottle with the joined caps.

Attach the second bottle on the other side of the joined caps

Find out how much time it takes to shift the sand from one bottle to the second one by looking at the clock. Your sand clock is ready for use. You may use it to time while playing different games.
