Recommended Material List Material Purpose Quantity Plastic Bottle Containment & Flow Control 1-2 Gravel Mechanical Filtration 1 Cup Activated Charcoal Chemical Adsorption 1/2 Cup Fine Sand Particulate Filtration 1 Cup Cotton Ball Pre-filter Screen 1-2 Constructing the Filter System Begin by cutting the bottom off the plastic bottle to create a funnel shape that sits inverted into its lid. Start the layering process with the cotton ball at the narrowest point to prevent media from entering the collection vessel.
Record visual observations regarding cloudiness and color removal at each stage. Understanding the Science Behind Filtration Before assembling the device, it is essential to comprehend the scientific mechanics at play.
