How do broken bones heal?
Why do we have bones? How do they grow–and how do they know when to stop growing? How many do we have in our bodies? And when we break our bones, how do they heal? What do casts do? And how do you know if you’ve broken a bone? Broken bones are a common occurrence in kids. Up to 40% of girls and up to 50% of boys will break a bone in their lifetime. In this episode, we learn about the role of bones in our body and how to deal with a fractured bone with Melissa Raddatz, a family nurse practitioner at Duke Health System in North Carolina. The first part of this episode is all about bones in general, and we shift to broken bones for the second half.Download our learning guides: PDF | Google Slide

How do we learn to swim?
But it’s important to know how to swim if you’re going to be around water! In this episode, Upper Valley Aquatic Center Swim School Director Kana Wyman gives us swimming tips, like how to get comfortable putting our heads in the water, how to float and more.Download our learning guides: PDF | Google Slides | TranscriptA few tips for getting started: If you don’t live near a pool or body of water, you can learn some primary skills even in a bathtub or using a bucket. Get used to putting your face in the water by using a bucket or big bowl. Keep your mouth closed and blow air through your nose. Humming can help make sure you’re breathing out. When floating, think about a string pulling your belly button up to the sky. It’s easier to float if you spread your body out, rather than curling into a ball. You may need to swirl your arms or legs to keep your whole body on top of the water. Some people have a harder time floating than others, due to body mass differences. So if it feels hard, it’s not your fault! Check with community swimming pools to see if they offer free lessons. Many pools, gyms or swim schools will offer lessons for kids and adults that are free or subsidized, at least occasionally, to make sure everyone has the opportunity to learn lifesaving swimming skills.
