1) The document outlines steps to clean water in a laboratory simulation of water treatment processes, including mixing dirty water, allowing it to settle, removing materials from the surface and bottom, and adding activated charcoal to eliminate small pollutants.
2) Materials like gravel, sand, and fabric are used to make filters, which are cleaned and then used to filter the water.
3) The filtered water is then analyzed and the best filters are identified, with the next planned activity being a visit to an actual water treatment plant.
