Desalination Design Challenge: 01 Water, Water Everywhere

This lesson invites students to learn about the limited availability of fresh water and introduces them to the unit, in which they will think creatively about desalination: the process that removes salt from saline water. This activity uses containers ranging from an eyedropper to a five-gallon bucket to create a visual model showing how little fresh, drinkable water is available on Earth. Students then reflect on the amount of fresh water humans consume and consider ways to reduce our individual water consumption.
