Water Detective Series

Water is weird, wonderful and worth protecting! One thing we can all do to keep our water safe is get to know it better, so we teamed up with our friends at Brains On!® and Earth Echo International to help kids learn all about the water in the world around them.

Become a Water Detective!

Partnership with Brains On! and Earth Echo International

Earth Echo International is a nonprofit founded on the belief that kids have the power to change the planet. They run the Earth Echo Water Challenge, a worldwide initiative that equips kids with a fun and easy way to test their water. Parents and guardians can purchase the EarthEcho Water Challenge Kit at a special discount by visiting monitorwater.org.

Every kit comes with tools for testing key water quality indicators: pH, dissolved oxygen, temperature and turbidity… plus an exclusive Brains On Water Detective badge! Use the kit to test the lakes, rivers, creeks and other bodies of water near your home. Record your results, gather clues about your environment and share what you learned by entering your data online to Earth Echo’s international database.

What’s in your water?

What’s in your water, and how did it get there? Clean water is a must, but modern living can put a lot of bad stuff in it. Road salt, fertilizer, dog doo-doo, heavy metals — how do these things get in our water? Why should we care? And how can we tell if our water is healthy? Check out this episode!

The wonderful weirdness of water

One of the weirdest substances in the universe is right under your nose. No, not boogers. Water! Water seems ordinary, almost boring, but take a closer look and you’ll find a wonderfully weird molecule that behaves like nothing else in the universe. Why is water so weird, and why does that matter? Listen to find out! Check out this episode!

Burning Rivers of Fire

Rivers are known for being wet. So how did a river in Ohio suddenly catch fire, not once, but several times during the last century? In part three of our water series, we’ll explore the shocking tale of the Cuyahoga River. We’ll look at how pollution led to this environmental tragedy. Check out this episode!

Keeping water healthy, one clue at a time

In the previous podcast, we heard about the tale of the Cuyahoga River — a river in Ohio that caught fire multiple times because it was so polluted. The river is now doing much better, but beyond the fact that it’s not on currently fire, how do we actually know it’s healthier today? That’s when being a water detective really comes in handy. Check out this episode!
