Hands-on activities like model building make complex topics tangible. By creating a DNA model, students visualize and reinforce their understanding of genetic concepts.
1. Gather your materials: straws, clay, and colored paper. 2. Cut straws into equal lengths for the DNA backbone. 3. Use clay to create alternating base pairs: A-T and C-G. 4. Assemble straws vertically and attach clay pairs to form rungs. 5. Connect everything to complete your DNA double helix model. 6. Label your model and explain its parts to someone!
