The Effect of Natural Selection on Genes, Traits and Individuals
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...
Curated OER
The Structure of DNA
Students describe the structure of the double helix, explain how DNA copies itself, and recognize that the sequence of DNA is what makes each individual unique.
Cornell University
Extracting DNA
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.

Regents High School Examination: Living Environment 2005
The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within...
Curated OER
Genetics and DNA
Students describe the structure of DNA and its components and can comprehend that real DNA and its cartoon representation are very different. They are able to link DNA to genetic make-up.
Cornell University
The Making of Macromolecules
Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...
