Design and build a device that can clean a dirty water sample using materials around your home. You’ll follow the same design process used by NASA engineers and scientists when they developed the water filtration system for the International Space Station orbiting Earth. To do so, you’ll use an iterative process, meaning you’ll test multiple designs, look at how your materials get you closer to your goal, and record your findings to build the best filter possible.
Important safety note! This activity is not designed to make drinkable water. No matter how “clean” your filtered water looks, you should never drink it because it still may contain pollutants you can’t see.
