Then place a layer of clean sand followed by a layer of gravel. Which paper towel absorbs the most water science experiment? Any remaining organic contaminants and microorganisms are removed by a high-temperature catalytic reactor assembly. In this experiment, we used the assembled filter column from the kit to purify water. Real quick, before you get seriously started on this water filtration lesson, you need to make it very clear, that the water won’t be drinkable after your filtration, because you can’t filter out as well as the water plant does. The water-based drop remains intact until it sinks through the oil and contacts the water, at which point the color at last disperses. Clear water filtered by the sand would trickle into the hole. This experiment requires some patience, so while waiting, it is a great time to move on to the next two experiments. The experiment was created with inspiration from many different sources including Water.org, University STEM education sites, as well as Ohio State University faculty and staff.
