Show notes

Today we unlock the secret of how keys and locks work. From the cylinder, to the pins, the springs, the shear line, and how a key's "hills and valleys" line everything up so the bolt can move... we break it all down! Curious Kids Every Day is a daily, interactive podcast that respects your child's intelligence and curiosity. Each episode is designed to stretch young attention spans with thoughtful questions, playful learning, and engaging games. I created this to be a show I would be happy to have my kids listen to. Please visit curiouskidseveryday.com to get a free printable with activity ideas that don't involve screens. Those are the best kinds of adventures to have!
