Demonstrate the key concepts of water treatment. What is the source of our drinking water? How are its impurities removed? What route does it take on the way to our taps? What is the difference between hard and soft water? These are just a few of the questions your students will answer as they perform a series of handson activities investigating the water we use in our everyday lives. They’ll also explore the primary sources of water pollution and the most effective means to prevent it and to repurify water.
