Fresh water is a precious resource. Most kids don't realize how little of the water on Earth is actually drinkable. This instructional activity will help to illuminate them on this important topic. They discus the ratio of water to land, where most fresh water is found, how salt water can be desalinized, and how pollution is such a danger to our fresh water supplies. Although lecture and discussion-based, the instructional activity is worthwhile implementing with your kids.
