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...

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...

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...

Students participate in a contrived natural selection simulation in which they build and modify simple paper airplanes. They study divergent and convergent evolution and how it is isolated in sub-populations.

In groups, learners read a case study of a couple who produced a child with hemophilia. Although tthe reading breifly mentions how a hemophiliac child is produced, the focus of this lesson is the ethical implications. This lesson is more...
