Description

Brains On!® is a science podcast for curious kids and adults from American Public Media. Co-hosted each week by kid scientists and reporters from public radio, we ask questions ranging from the science behind sneezing to how to translate the purr of cats, and go wherever the answers take us. @Brains_On

Episode Date
Why do kids have more energy than adults?
00:39:49
We’re taking on an age-old question today: Do kids have more energy than adults? Breakfast tacos, caffeine, an energized DJ and an epic battle between a girl and her parents. This episode has all that and then some. Discover how we turn food into energy at an awesome taco party. Then pump up the jams with DJ Thyroid. Speaking of music, get ready for a song from Lake Street Dive’s Mike Olson. And just when you think the show might be out of energy, we engage in an out-of breath competition between a kid and her parents. Plus, there’s a brand new Mystery Sound and a Moment of Um about why we lose our voices sometimes. This episode is sponsored by Laurel Springs Online School (laurelsprings.com/brainson) and KiwiCo (kiwico.com/brainson)

Why does green mean go? And other color conundrums
00:36:40
The world is full of color, but how do our eyes see it? In this episode we’ll explain how color vision works, complete with a journey to a jazz club in the back of your eye. We’ll also look at the cultural meanings of the color red, we’ll find out about a new type of blue, and we’ll find out why stoplights use green to mean go. Our Moment of Um tackles the question, “why are bees black and yellow?” This episode is sponsored by KiwiCo (kiwico.com/brainson) and Nurture Life (use code: BRAINS at checkout).

Injustice and Anger: Understanding your emotions
00:29:37
A lot of us are angry right now, with good reason. We’re seeing people treated unfairly because of racism -- that’s when people don’t like someone’s race or the color of their skin.In this episode we’ll talk about how anger can be a useful emotion and can be used to push for change. We’ll also revisit parts of our 2019 series on emotions, including an explanation of the hormones behind anger, why some of us are quicker to anger than others and what we can do when we feel overwhelmed by our feelings. Plus, our Moment of Um tackles the question, “What happens when lightning strikes water?” If you want to talk to your kids about race but don’t know where to start, we suggest reading this article (https://bit.ly/3eEss5k) by pediatricians Dr. Jacqueline Dougé, & Dr. Ashaunta Anderson or Talking to Kids About Race by Heather Greenwood Davis (https://on.natgeo.com/306a2Xe).There are great books to help your family start a conversation about race. Here's a list from Embrace Race (https://bit.ly/2U1SvLV).

Why do we lie?

Lie, who tries to remind us that we might need lies more than we think. Plus, Angela Evans stops by and fills us in on the latest lie detection research.
