Building Blocks of Life – Water

Did you know that almost 97% of the world’s water is salty or otherwise undrinkable? Another 2% is frozen in ice caps and glaciers. So that leaves just 1% of water available for all of humanity’s needs — drinking water, agriculture, bathing, manufacturing, cleaning, etc. 

However, the amount of water on Earth has not changed since the Earth was formed. Water only changes form and location. It is never lost and never gained. The amount of water on earth is always the same.  

Fun fact: The water from your faucet could contain water molecules that dinosaurs drank! 

Join Tiger Territory Education Garden to understand the importance of water to life on Earth, to appreciate why water is so special, and to learn about other places water has been found, like the moon and Mars. Plus, a fun science experiment with water.
