I bet you already know the most important fluid to drink.

It's water! Water has a very simple structure made up of one part oxygen and two parts hydrogen. But this simple substance is essential for life!

All living things need water to survive: the trees outside your classroom,

your crazy dog, and even you!

You cannot survive without water. Your heart, eyes, stomach, intestines, and even pinky toes need water to stay alive!

Water is the only substance found on earth in all three of its natural forms: solid, liquid, and gas.

Did you know that on average between 1/2 (50%) and 3/4 (75%) of your body weight is water?

Can you calculate how many pounds of your body are from water?
