Engage your students in creating a 2-dimensional model of DNA (and extra-credit opportunity to create a 3-D version). I found that many of the DNA model projects with templates online or in textbooks were overly simplistic; because the pieces fit together, students could intuit how the pieces went together but not actually think deeply about the structure of DNA. In this project, I ask students to create a 2-D model using only paper and forming each piece as a different color. When I first designed this, I thought it would be easy for students to accomplish... each year, I am reminded of what a difficult, high-level task this is. In this project, I ask that students not only include nitrogenous bases, deoxyriboses, and phosphate groups, but also hydrogen bonds, covalent, labeling/counting carbons around deoxyriboses, showing an introductory level of 5' --> 3' conventions, and figuring out a way to show that the DNA is coiling into a helix. I use this with introductory biology, but gearing them up for AP Biology. I ask students to peer-review their models (and adding/editing any mistakes) before submitting and this has prompted good discussions about models and students supporting each other in their learning. Materials included in this download include: Word and PDF versions of the assignment, the peer review rubric, and the rubric I use when grading (smaller to save paper).

NGSSHS-LS1-1
Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins, which carry out the essential functions of life through systems of specialized cells. Assessment does not include identification of specific cell or tissue types, whole body systems, specific protein structures and functions, or the biochemistry of protein synthesis.
