Procedure and Materials

 

Materials

 

Natural sponge

Household (man-made) sponge

2 Pyrex bowls

2 Foam bowls

Balance scale

Measure cup

Water

 

Experiment

 

1. Place each sponge into the small foam bowl and weight of both: the dry, natural and man-made sponges, write the weight information under “Dry Weight.”

 

2. Place man-made sponge and natural sponge in each of the Pyrex bowls.

 

3. Measure 2 cups of water; pour in each Pyrex bowl where the sponges are and wait for a few minutes until it is fully soaked.

 

4. Take the man-made sponge from the water, let the extra water drip off, put it in the small foam bowl and weight the sponge, write the weight information under “Saturated Weight”.

 

5. Take the natural sponge from the water, let the extra water drip off, put it in the small foam bowl and weight the sponge, write the weight information under “Saturated Weight”.

 

Results

 

Subtract the Dry Weight from the Saturated Weight.  Write the answer in the column labeled “Difference.”  Record the results for all the samples. Table No.1

Conclusions

 

In all three examples the natural sponge holds the most water -116g - than man-made sponge – 76g - because the body of the sponge has thousands of pores, which let the water flow through it continually.
