Sponge Experiment

Aim of the Experiment:

To find out the amount of water needed to keep a sponge moist.

Apparatus:

·        3 sponge

·        1 measuring cup

·        1 pail/basin

·        Tap water

Steps of Experiment:

1.      Fill the measuring cup completely with tap water.

2.       Pour the tap water into the pail/basin.

3.       Repeat Steps 1 and 2 until there is enough water for the sponge to be completely soaked.

4.       Fully submerge the sponge in water, and hold the sponge down for a short period of time (e.g. 10 seconds) to ensure that the sponge is thoroughly soaked.

5.       Remove the sponge from the water.

6.       Drain the sponge of all excess water, so that it is moist but not wet and dripping.

7.       Fill measuring cup with water from the pail/basin.

8.       Pour the tap water away.

9.       Repeat Steps 1 and 2 until pail/basin is completely drained of water, keeping count of the number of times the measuring cup is filled.

10.  Subtract the final amount from the initial amount of water to gain the amount of water keeping the sponge moist.

11.   Repeat Steps 1 to 10 with the remaining two sponges to ensure accuracy of results.

12.   Collate data.
