Modeling the Detection of Dissolved Substances and the Water Treatment with Iodine

We all require water to drink; controlling its quality and supply is a pressing issue facing many areas of the world, including the United States. This utilizes the 5E’s to have students examine what is in the water supply and how do we control its purity. Students will specifically explore the detection of invisible chemicals dissolved in water in this activity.  Furthermore, students will design their own filter apparatus and attempt to purify water. Using data from these experiments, students will explain what factors affect water quality and elaborate ways to improve it.
