By building their own DNA model in this OLogy activity, kids learn about the unique genetic code that's found in every cell of their bodies. The activity begins with a brief look at how all living things are made of cells, and what that makes them unique is DNA. Then, using toothpicks, colored paper, and other common supplies, students create a 3-D model of DNA and "do the DNA twist" to make it look like a double spiral. Interspersed throughout the activity are kid-friendly descriptions of the discovery of DNA and where it's found. The experiment ends with additional challenges for students, such as making a DNA mobile with pipe cleaners or some other flexible material.
