DNA. We all have it and we know it’s important. It tells our bodies how to work. But what exactly is it and what is a double helix? Come along with Desi DNA and learn how DNA is built and where it is found. Make your own DNA model, act it out with your friends, and even learn how to extract DNA from fruit in your own kitchen. With Discovering DNA from Be Naturally Curious, learning about this important topic becomes a piece of cake for elementary aged kids!
The Mini-course Discovering DNA is provided as a 26-page PDF including a separate Science Tool Kit PDF to collect your badges.
