1. On Earth there is around 1,5 billion cubic meters of water – which is 800 trillion Olympic size swimming pools.

2. If we covered the Earth’s surface with all water, the depth of the created ocean would be 3700 meters.

3. 97% water on Earth is salty. 2,1% of water is in the form of polar ice cap and less than 1% of water is suitable for drinking.

Our students could learn such information during their classes about water.
