Water cycle-Experiment and mathematics
Target Group: Middle School
Ocean Literacy Principle: 1,2,4
Experiment that shows how all the water in the world is divided into all water sources on earth like oceans, rivers and ice bergs.
70% of the earth is water. How is water divided between all of Earth's water sources? Students calculate the volume of water in each of the categories. Both calculations and the experiment show the differences. Afterwards the students make a bar graph.
All information can be found on the website (see Reference Material).
