Water Supply

Not all water is created equal! In this BrainPOP movie, Tim and Moby get their feet wet to teach you all about the world’s usable water supply. You’ll learn the difference between seawater and fresh water, and how only a tiny fraction of the world’s water is potable, or fit for human use. You’ll explore fresh water sources like rivers, lakes, aquifers, and reservoirs, and you’ll see how water gets from those sources to the faucet in your home. Plus, you’ll find out how water pollution, over-population, and wasteful water uses, both in your home and on larger, industrial scales, contribute to today’s global water crisis. Finally, learn about water conservation and discover some of the methods being used today to bring clean water to everyone who needs it!
