We have built time filters for ACMs. We made 3 different water filters. The first filter was made with household paper. The second with sand and coffee filter. The third one that worked best was made with fabric, a coffee filter, gravel and sand. We presented our work in all classes and sensitized all students to water pollution in the Ayent, Arbaz primary schools and the St. Roman orientation cycle. To touch the most people.
