A fascinating discovery-oriented approach to learning about the structure and function of DNA. Students embark on a sequential problem-solving exploration using clues, hints, and the model pieces themselves. By manipulating the pieces and seeing which can be fit together, they use the process of elimination to determine what each piece represents. Students move on to construction of the DNA model, “unzipping” it, and replicating it-all in proper form and sequence. Students will also learn about translation, transcription, protein synthesis and mutations. Enough materials for 2 to 3 student groups.
