Have you ever wondered what bird you’re hearing? We’re going to discover how to recognize birds by their sound - and what that means for science. Trevor Attenberg is an environmental scientist and science communicator who learned to identify birds without sight, by their sound alone. He takes us through his journey to becoming a birder and a scientist, and shares how you can learn to recognize birds by their sound. 

Learn more about Trevor, and find his recommended resources for birding on the blog on our website, www.sciencepodcastforkids.com.

How big is the universe? And how do we know? It's a question that puzzled astronomers for centuries. They had no way to measure distance in space - until Henrietta Leavitt showed them how. Henrietta Leavitt was a "computer" in the 19th century, before there were computers, and she made an incredible discovery that would help change the way people thought about the universe - forever. Modern-day astronomer Karen Masters helps us tell her remarkable story.

If you like this episode, you'll love our free audio course, "Cataloging the Universe" where you'll learn much more about how Henrietta Leavitt's discovery made a big difference in astronomy - plus, you'll become a skywatcher yourself! "Cataloging the Universe" is more than a podcast. It’s interactive! Each episode - or lesson - in the series contains activities to complete while you listen. Plus, you’ll get discussion questions, graphic organizers, and a star journal to keep your observations in. Check out the series and download all the resources at our website!
