Humans can only survive for a few days without water. Knowing how to filter water is a valuable life skill. You never know when you may find yourself in the wilderness in need of clean water!
In this activity, learners will discover how to make a basic water filtration system using common materials found around the house or outside. This activity will get your child thinking about the importance and value of clean water and its various uses in our lives. This activity can also spark an interest in the topic of access to clean water for communities around the world.
Explain to your child that even though the world consists of 70 percent water, only about 3 percent of the available water is drinkable. Water is essential for human survival, and it is also needed for cooking, cleaning, growing food (plants), and bathing. While some people have the privilege of turning on the tap and getting clean, drinkable water easily, many people must travel far to get clean water. Others may have a water source nearby, but it might not be clean water. Communities that do not have access to clean water sometimes have to drink unsafe and contaminated water, which can cause disease and sickness. As the human population grows, clean water becomes more scarce, or harder to find. It is important that we make clean water accessible to everyone.
