Water Filtration Unit Experiment

The first glass will serve as the control.

Water filtration unit experiment.

To meet this challenge students use an iterative process as they build test and measure the performance of the filtration device analyze the data collected and use this information to work toward an improved. Put the lid on the bottle and shake vigorously for 30 seconds. For this experiment it is best to test the water before and after the filtration. In this activity students are challenged to design and build a water filtration device using commonly available materials following the same design process used by the engineers and scientists who developed the international space station water recovery system for nasa.

Pour the water into the bottle with its top cut off. We went to a little pond nearby to collect some water. Decide if the water is a b or c grade and help them measure their sample in a graduated cylinder. You will need a few supplies.

Then pour the water back and forth between the two cups about 10 times. Once completed give each team 25 ml of the dirty water to begin to filter in their test tubes. Begin by getting a jar full of dirty water. Once filtering is complete have them bring the test tubes to you for observation.

The second glass will be dirty dirty the dirty water with materials found around the house. 2 glass jars sand gravel 3 4 coffee filters dirty water a plastic cup with a hole cut in the bottom. Again notice how the water looks and smells. Notice how it looks and smells.

So many people get sick from their own drinking water. How to do the water filtration experiment.
