With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

Ms. Strohfeldt did not omit anything when she designed this comprehensive lesson plan on DNA mutation and sex-linked traits. Begin with a pretest as an anticipatory set. Read a case history of the Clark family and the occurrence of...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Tenth graders investigate the chemical composition of DNA and RNA and how they work together to synthesize protein. They discover genetic codes, gene chromosome theory, and how the environment influences our appearance.

Biology buffs simulate how genetic markers are passed among populations in order to understand how these markers can help anthropologists map human migration. A couple of volunteers leave the room while you walk the remaining learners...

Students determine the types of natural selection and variation that exists in a population, using beans.
