In common experience, the term "adapting" usually refers to changes during an organism's lifetime. In contrast, evolutionary biologists use the term "adaptation" to refer to a heritable trait that increases fitness. To help students reconcile these different concepts, this activity introduces the concept of phenotypic plasticity (the ability of an organism to adapt to different environments within its lifetime). Questions guide students in analyzing how the balance between the advantages and disadvantages of a characteristic (e.g. an animal’s color) can vary in different circumstances, how phenotypic plasticity can be a heritable trait that can optimize fitness in a variable environment, and how natural selection can influence the amount of phenotypic plasticity in a population.

This overview reviews key concepts and learning activities to help students understand how genes influence our traits by molecular processes. Topics covered include basic understanding of the important roles of proteins and DNA; DNA structure, function and replication; the molecular biology of how genes influence traits, including transcription and translation; the molecular biology of mutations; and genetic engineering. To help students understand the relevance of these molecular processes, the suggested learning activities link alleles of specific genes to human characteristics such as albinism, sickle cell anemia and muscular dystrophy. Suggested activities include hands-on laboratory and simulation activities, web-based simulations, discussion activities and a vocabulary review game. (NGSS)

In this analysis and discussion activity, research concerning the health effects of vitamin E is used as a case study to help students understand why different research studies may find seemingly opposite results. Students learn useful approaches for evaluating and synthesizing conflicting research results, with a major focus on understanding the strengths and weaknesses of different types of studies (laboratory experiments, observational studies, and clinical trials). Students also learn that the results of any single study should be interpreted with caution, since results of similar studies vary (due to random variation and differences in specific study characteristics).

An interactive video called "Roots, Shoots, and Wood," with Dr. Kathleen Vandiver (inventor of this lesson), and produced by can assist you in teaching this lesson. A teacher's guide, written transcript, and class handouts can be found . BLOSSOMS (Blended Learning Open Source Science or Math Studies) is a collaborative initiative seeking to begin to develop a large, free repository of video modules for high school math and science classes created by gifted volunteer teachers from around the world, seeded initially by MIT faculty members and by partnering educators in Jordan and Pakistan.

This analysis and discussion activity introduces students to the biology of HIV infection and treatment, including the molecular biology of the HIV virus lifecycle and the importance of understanding molecular biology and natural selection for developing effective treatments. The questions in this activity challenge students to apply their understanding of basic molecular and cellular biology and natural selection and interpret the information presented in prose and diagrams in order to understand multiple aspects of the biology of HIV/AIDS and treatment.
