Experiment: Absorption of Sponge

In this experiment, the students used different sizes of sponge to absorb water in the beaker. They are divided in to 4 groups to carry out the experiment. 

 Group 1
 Group 2
 Group 3
Group 4

Before they immerse the sponge into the beaker, they recorded the initial volume of the water. After they immersed the sponge with different sizes into the beaker, the observations are recorded. The students came out with a conclusion, sponge is a good absorbent and the absorption of the sponge depends on the size of the sponge.

The students too discussed why the ability of materials to absorb water is useful for certain equipment for example a mop needs to be absorbent to mop up water. This experiment is a success and again, thanks to the students who gave me full cooperation. =)
