00:01:45 | July 5th, 2024

Molly is working on a musical about trees that live in cities. But she can’t finish her rhymes! So she enlists Ruby and Anna to help. Molly gives them some of her unfinished lyrics and it’s up to them to help her turn a single sentence into a fact-filled musical couplet!

How do trees help our cities?
00:27:35 | June 4th, 2024

Did you know that more than half the people in the world lives in cities? The hustle and bustle of a city can be awesome, but cities can also be hot and polluted. Luckily, there’s a solution we can all get behind – trees! Join Molly and co-host Nallini as they learn how these magnificent towering giants make our cities better places to live and help fight climate change. They’ll also visit an urban orchard that grows fruit in the middle of Philadelphia. All that plus a tree-mendous mystery sound!

00:24:46 | May 28th, 2024

98.6 degrees is hot. If it were that hot outside, you’d be sweaty and want to go jump in a nice cold pool. But the insides of our bodies are that hot all the time! And that’s because there’s a lot going on in there that creates heat.

It’s a mystery sound extravaganza!

Get your listening ears ready for this one!

How do stringed instruments make sounds?
00:27:04 | May 7th, 2024
