If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this resource is so precious. By creating a liquid scale model, then examining and coloring maps, and finishing up with a discussion, kids should grasp that just a small fraction of the earth's water is drinkable, and should therefore be conserved.
