Water Retention Experiment Created by C. Bonhamgregory TEKS 4.11a TAKS questions 3, 2003; 27, 2004; 15, 2009

Slide 2: 

200 mL of water were poured onto the following towels. The towels absorbed some of the water. The water that was not absorbed was collected into a beaker. The water in the beaker was then measured after each trial. According to the information in the table, which towel retained water best?

How much water did the Workshop Rag retain? : 

How much water did the Workshop Rag retain?

How much water did the Bath Towel retain? : 

How much water did the Bath Towel retain?

How much water did the Paper Towel retain? : 

How much water did the Paper Towel retain?

How much water did the Wash Cloth retain? : 

How much water did the Wash Cloth retain?

Slide 7: 

200 mL of water were poured onto the following towels. The towels absorbed some of the water. The water that was not absorbed was collected into a beaker. The water in the beaker was then measured after each trial. According to the information in the table, which towel retained water best? Workshop Rag: 200 – 160 = 40 mL Bath Towel: 200 – 45 = 155 mL Paper Towel: 200 – 185 = 15 mL Wash Cloth: 200 – 90 = 110 mL

Slide 8: 

200 mL of water were poured onto the following towels. The towels absorbed some of the water. The water that was not absorbed was collected into a beaker. The water in the beaker was then measured after each trial. According to the information in the table, which towel retained water best? Workshop Rag: 200 – 160 = 40 mL Bath Towel: 200 – 45 = 155 mL Paper Towel: 200 – 185 = 15 mL Wash Cloth: 200 – 90 = 110 mL The amount of water you have after you subtract is how much water is still in (retained) the towel. The amount that is subtracted is the amount that is in the beaker and not in the towel.

Slide 9: 

200 mL of water were poured onto the following towels. The towels absorbed some of the water. The water that was not absorbed was collected into a beaker. The water in the beaker was then measured after each trial. According to the information in the table, which towel retained water best? Workshop Rag: 200 – 160 = 40 mL Bath Towel: 200 – 45 = 155 mL Paper Towel: 200 – 185 = 15 mL Wash Cloth: 200 – 90 = 110 mL The amount that is subtracted is the amount that is in the beaker and not in the towel. The amount of water you have after you subtract is how much water is still in (retained) the towel.

Slide 10: 

200 mL of water were poured onto the following towels. The towels absorbed some of the water. The water that was not absorbed was collected into a beaker. The water in the beaker was then measured after each trial. According to the information in the table, which towel retained water best? Workshop Rag: 200 – 160 = 40 mL Bath Towel: 200 – 45 = 155 mL Paper Towel: 200 – 185 = 15 mL Wash Cloth: 200 – 90 = 110 mL The amount that is subtracted is the amount that is in the beaker and not in the towel. The amount of water you have after you have subtracted is how much water is still in (retained) the towel.

Therefore, the answer is… : 

Therefore, the answer is… 200 mL of water were poured onto the following towels. The towels absorbed some of the water. The water that was not absorbed was collected into a beaker. The water in the beaker was then measured after each trial. According to the information in the table, which towel retained water best? Workshop Rag: 200 – 160 = 40 mL Bath Towel: 200 – 45 = 155 mL Paper Towel: 200 – 185 = 15 mL Wash Cloth: 200 – 90 = 110 mL Out of 200 mL, there are 45 mL in the beaker and there are 155 mL in the towel.
