| Description | Students groups build water filters using activated carbon, cotton and other materials to clean a "dirty" water sample made from chocolate powder added to tap water. They test and make observations of filter effectiveness, suggesting material and layering design improvements. Students groups build water filters using activated carbon, cotton and other materials to clean a "dirty" water sample made from chocolate powder added to tap water. They test and make observations of filter effectiveness, suggesting material and layering design improvements. They see how their filtering process compares to the drinking water treatment processes designed by engineers to provide communities with clean water supplies. |
