Terry Porter, Environmental Educator for the City of Alpharetta, visited our 6th grade Earth Science class this past Friday, January 23rd. Mrs. Porter brought in the Water Treatment Interactive Model. Mrs. Porter led students through a variety of hands-on experiments to better understand the stages of cleaning water for human use. Students joined to the activity and did the steps all together. It was fun to see the water color changes from brown to clear! Thank you Mrs. Porter
