Water is essential for survival on Earth. It makes
up almost two-thirds of our body weight and covers a little over two-thirds of
the Earth’s surface. Since almost all of the water is in salty oceans, we can’t
use it for drinking. In fact, only about 3% of the Earth’s water is fresh, and
most of that fresh water is frozen. That means only about 1% of the water on
Earth is available for people to use. The chemical formula “H20” shows the basic units of a water molecule: two
hydrogen atoms and one oxygen atom. We describe water as a colorless liquid
that you can’t smell or taste. Water also comes in the form of ice in the polar
ice caps and water vapor (gas) that rises into the air from the surface of our
planet. To learn more about water click here….http://water.org/
It might surprise you to learn that chemicals
from products we use every day can eventually end up in our water. Just look
around your home. Do you see any batteries, paint, or medicines? If you don’t
get rid of these products correctly, they can cause chemicals to end up in the
water supply. In fact, your water can be affected by chemicals and pollutants
close by and far away from your home. Would you want to go swimming in a pool of
bugs, worms, and chemicals? In some natural water sources, you actually would
be! You just wouldn’t be able to see them. Tiny organisms like bacteria,
viruses, and parasites may live in our water supplies. Chemicals and heavy
metals can get into our water, too. If you drink that water, wash your food
with it, or swim or bathe in it, it might make you sick. We take baths with clean
water. We drink clean water. We wash our clothes and food with clean water. To

These water sources can become polluted. Mother Nature does her part to clean the water through the water cycle. But the water cycle can’t keep up with the pollution that people and animals create.
