DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

Transform your class' understanding of genes and antibiotic resistance with the Transformation Lab. Junior geneticists create and observe their own resistant strains of E. coli through research, discussion, and experimentation. The...
