This week we're answering questions about gender. We've gotten a lot of questions about the differences between boys and girls so we're tackling them with Vanderbilt anthropologist Anna Catesby Yant and Dr. Lori Racha of UVM Medical Center. This is a frank but age-appropriate conversation about male and female bodies and about how biological sex differs from gender. We think the whole family will enjoy this episode, but you're always free to give our episodes a listen to see if it's right for your young ones.

Other questions in this episode: Why are boys taller than girls? Do only boys have Adam's apples? Why can't girls grow beards? Why do most boys have short hair? Why do girls wear makeup and boys don't? Why do professional sports have all-men's and all-women's teams? Why can more girls do the splits than boys? Why didn't women have as many rights as men back in the olden days?

A solar eclipse is coming to North America on April 8, 2024. The moon will line up perfectly between the Earth and the sun, blocking out the sun’s light and casting a shadow that will pass over parts of Mexico, the United States and Canada. People in the path of totality will experience a few minutes of darkness during the day as the moon perfectly covers the sun. Those not in the path of totality in those countries will still experience a partial solar eclipse. In this episode, we’re answering questions about the eclipse and talking about how to keep your eyes safe if you’re watching it! We speak with Bridgewater State University solar physicist Martina Arndt, Fairbanks Museum planetarium director Mark Breen and Thomas A. Hockey, author of America’s First Eclipse Chasers.
