INTRODUCTION Hi! My name is Dr. Kate Biberdorf, but most people call me Kate the Chemist. You can usually find me teaching classes in Austin, Texas, or setting off explosions on national TV. For years, I've been bombarded with requests for at-home activities; so over summer break, I embarked on a mission to compile my favorite science experiments into one awesome book! Do you know what chemistry is, besides being the best science in the entire world? It's the study of energy and matter, and their interactions with each other. Like how a gecko climbs a wall or how a rocket moves through space. If you follow the protocols (i.e., recipes) in this book closely, you will learn how both of these things happen. I'll even show you how to use unicorn glue and send a secret message to your BFF! Every experiment can be done safely in your home with materials purchased online or in local pharmacies, craft stores, or home improvement stores. Just pay close attention to the safety icons and messiness levels to avoid hurting yourself (or your mom's favorite table). Lastly, these experiments are better when shared with friends. So what are you waiting for? Call your bestie, grab your goggles--it's time for science!
