Are you struggling to get across to your students how a strand of DNA can form a recipe for an organism? Using this activity students are given a random selection of paper DNA strips that represent a fish's genotype. They then read the DNA recipe to discover the phenotype of their fish and create a final drawing of the fish.
Students learn that differences in the DNA code lead to different traits by comparing their DNA and fish drawings with the rest of the class. It can also be used to discuss the adaptations of each fish, and the habitats they may live in.
