In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Earth's total water supply. Learners divide 1000 ml of water (representing the total amount of water on Earth) amongst eight beakers as they predict the various ratios. Then learners measure the amounts of water that reflect the actual ratios and compare their predictions to reality. Learners will be surprised to find out that most of Earth's water is found in the ocean. This resource also includes information about flash floods and flood safety.
