Lesson Plan #1 Topic: Separating Mixtures - Water Filtration Grade Level: Chemistry 11-12 grade

Blue Plains || Students will view step-by-step how water is treated and delivered to your home or business as water that is safe to drink. Students will view the United State's Environmental Protection Agency's Virtual Tour of a Drinking Water Treatment Plant. Students will follow water as it is taken from a river and through the treatment process as it is prepared for delivery. Next, students will view the virtual tour of the Blue Plains Advanced Wastewater Treatment Plant. The largest advanced wastewater treatment facility of its type in the US. This virtual tour takes students through the liquid and solids handling processes. || || Students will learn how clean water is filtered from contaminated sources and then build a simple filter system. In this engineering challenge, the student's task is to build the fastest, most effective water filter system they can with the available materials and test its ability to remove debris from a sample of contaminated water. Students will keep records, draw designs, and answer lab questions. Students will modify their filter design after testing and employ a variety of methods to quantify how well their water filters worked. ||

 * Elaborate || [[file:Foul Water Mixture.pdf]] || Students will complete a chemistry lab investigating whether the water they drink is a substance or a mixture. A series of filtering steps will convert a foul water mixture into drinkable tap water. In this investigation, three processes will be used to filter a water mixture. Students will record their results, draw conclusions, and calculate the percent of foul water recovered as treated water. ||
 * Evaluate || [[file:FiltrationFS_0709.pdf]] || Depending on class size, divide the class into 3-4 groups. This lab will test 3 types of soil; sand, clay mixture, and potting soil. Students will make the bottle filtration system. Make sure all the bottles used are all the same, clear and colorless. Each group starts with a consistent ½ cup line marked. Each time they are asked to add water, they will add ¼ cup of the 3 samples of colored water. When groups complete the lab, they will complete the lab write up and labeled data table. The next day, we will have a class discussion comparing group results. ||
