Description
Students build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it. Students learn earth materials such as sand and dirt can be used to trap runoff pollution. The students also learn that there are limits to what dirt can filter. Most pollutants are organic, so dirt will attract them and filter different substances with varying success. These observations lead to valuable class discussions about pollution. Students can extend their learning using one of the Extensions provided on pages 8 and 9. The extensions for this activity include building a better filter, a filter for acid rain, and formulating a way to measure filtration rates.
