Water is essential for life on Earth but has unique chemical properties that scientists are still learning about. Water can exist in three states - solid (ice), liquid, and gas (vapor) - depending on temperature. It is vital for bodily functions and makes up the majority of cells, helps balance electrolytes, cushions organs, and provides minerals to the body.

2. Water is absolutely essential to life on earth. It may be one of the most familiar substances on the planet, but it certainly isn’t ordinary. In fact, water’s unique chemical properties make it so complicated that even after decades of research, scientists still have much to learn about this significant and resourceful substance. Water covers ¾ of the earth’s surface. Water is everywhere and scientists are still learning new things about it. Why is Water Unique?

3. Once the water reaches below the freezing point (32 degrees F) it turns into ice (solid). Between the freezing and boiling point is a liquid. Water becomes a liquid once it reaches 32 degrees F. Water then starts to boil at 212 degrees F. Once water reaches its boiling point it starts to give off gas (which is the releasing of oxygen into the air).
