All the Water in the World

So…how much water is there on the earth? Students will work through an experiment to learn about the limited amount of water on our planet. From salt water, to frozen water, inaccessible water and fresh clean drinking water - we’ll discover that even a planet covered in vast amounts of water has its limitations.
Activity Description
Students will conduct an experiment to demonstrate that even though the earths surface is mostly water, less than 1% is available for human use.
This activity centre is part of the Water Science theme.
