As part of their Genetics Unit, 7th Graders learned about the structure of DNA and were tasked with creating a homemade 3D model of the double helix molecule using any materials they had available (construction paper, pipe cleaners, candy, sticks, paper clips, LEGOs, Minecraft, etc.). Their models needed to include two sugar phosphate backbones and at least ten rungs of nucleotide base pairs (adenine, thymine, guanine, and cytosine). 7th Graders did such a great job, take a look at their homemade DNA models here.
