Methods Section Rubric - Lab Report Example The water was added until the towels became saturated and could no longer hold additional water. The weight of the saturated paper towels was also weighed and recorded. The weight of water held by the paper towels was determined by getting the difference between the weight of the wet and dry paper towels (Baxter, Shavelson, Goldman, and Pine4). This difference in weight was recorded for each type of paper towel. The procedure was repeated eight times for each type of paper towel to obtain nine replicates. The results were recorded in a table. A fully saturated paper towel of each type was used as positive control for each replicate to determine a standard level of saturation before taking weight measurements. The hypothesis was tested by getting the average and total amount of water held by each type of paper towel. The final results (average and totals) were then compared for the two types of paper towels. The type of paper towel that held the highest amount of water was regarded the most absorbent towel.
