Restate Question & Hypothesis
Testable Question: How does particle size affect the rate of infiltration?
Hypothesis: If there is a rock sample in the funnel, then the water will drain at a slower pace because the rock will block the water from draining quickly.
Evaluates original hypothesis using data
Based on the collected data, my hypothesis was correct. In trials with the rock sample, the water took more time to drain. This can be seen in the difference between trial 1 of the control test and trial 3 of the sample test. The time it took the water to drain fully in trial 1 of the control test was about 35 seconds. The time it took the water to drain fully in trial 3 of the sample test was about 68 seconds. That means the Pegmatite sample sample delayed the

That factor was whether or not the trial used a rock sample. If it did use a rock sample, the time it took to drain the water would have been longer because the rock blocked the water from being drained, and therefore, delayed the draining time. If you look in the table, you can see all of the control test values are lower than the sample test values. However, it’s unclear as to why the outliers were not in the expected range. The values might have been influenced by a possible experimental error.
Makes predictions, asks new testable questions and makes new hypotheses using the data
A new testable question inspired by the experiment is: How does a particles hardness affect the infiltration rate? It may seem a little irrelevant, but is it possible that hardness can affect the rate of infiltration? Will a soft particle not delay the infiltration rate because it can get weathered by the water? The hypothesis for this experiment is: If a mineral is harder, then it will take longer for the water to drain because the water can’t easily travel down the funnel.
