ObservationYou notice that some brands of paper towels appear to absorb more water than others.Question"Do different brands of paper towels absorb the same amount of water?"HypothesisFormulate a testable hypothesis.You can choose something like "Brand A paper towels absorb more water than Brand B paper towels."ExperimentMaterials Needed:Different brands of paper towels (at least 3-5 brands)Measuring cup (to measure water)Scale (to weigh the wet paper towels)Timer (to track absorption time)Containers (to hold water)ProcedureCut equal-sized squares from each brand of paper towel.Measure a specific amount of water (e.g., 100 ml) and pour it into a container.Place a paper towel square into the water for a set amount of time (e.g., 10 seconds).Remove the paper towel, let it drip for a few seconds, and then weigh it to find out how much water it absorbed.Repeat the process for each brand and record the results.Data CollectionRecord the amount of water absorbed by each brand in a table for comparison.AnalysisAnalyze the collected data to see which brand absorbed the most and least water.Use graphs or charts to visualize the results.ConclusionBased on the analysis, determine if the hypothesis is supported or not. Your conclusion may state something like this, "The results indicate that Brand A absorbs significantly more water than Brand B."Further ResearchSuggest additional experiments or variations to explore further, such as testing more brands or different types of liquids.
