Water Filtration Unit Experiment

The first glass will serve as the control.

2 glass jars sand gravel 3 4 coffee filters dirty water a plastic cup with a hole cut in the bottom. 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. Decide if the water is a b or c grade and help them measure their sample in a graduated cylinder. Notice how it looks and smells.

Again notice how the water looks and smells. Pour the water into the bottle with its top cut off.
