Water isn’t always clean when it starts out—but nature has amazing ways of fixing that! Wetlands, like swamps and marshes, act as natural filters, cleaning water before it reaches rivers and lakes. Now it’s your turn to be a water scientist! With this kit, you’ll build your own water filter and watch polluted water go through different layers, step by step. See how sand, gravel, and other materials work together to trap dirt and clean the water—just like wetlands do! Can you make the water clearer? Let’s experiment and find out!
