1. Water - Why Care?
LEQ: Why is it important to conserve water?
LEQ: How is water distributed on Earth?
Imagine a world without water. The planet is a barren desert. There are no cool green forests or deep oceans. The world is silent – no rain falls onto the rooftops. No clouds shield our planet from the hot sun. Even the shape of the land is different. Without water to wear them down, the mountains are jagged and rough. There are no Great Lakes, Niagara Falls, and no Grand Canyon.
