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!
