9. Presentation/Analysis/Conclusion • We would have the students utilize the field trip experience to later work in groups to create a water purification poster and have them create a filtration system using cups, sand and different size gravel. They will present this to the class when they are finished. • The poster will need to diagram the water purification process, include a brief history of water purification in Milwaukee, and anything else they have learned from the field trip. • For their filtration experiment they need to show to class that their filtration cups work by pouring dirty water into the filtration cup that contains the sand and gravel and show how purified the water gets. • The field trip to the water treatment facility is important so that students are able to understand how the water that they use in their everyday life become safe for them to drink. • If the students are able to understand the filtration process that is used in the Milwaukee Water Works Drinking Treatment Plant and are able to apply that knowledge into their poster and are able to explain the process as it applies to their filtration cups which one of the steps of the treatment process.
